Oregon Department of Forestry Forest Practices Section 2600 State Street Salem, OR 97310 Dl Fish 8 Wildlife Oregon Department of Fish and Wildlife Habitat Conservation Division P. O. Box 59 Portland, OR 97207 Introduction Identifying Oregon streams that contain fish is an important part in carrying out the new Water Protection Rules. These rules aim to protect areas of benefi-cial uses, such as fish. First, however, the beneficial uses present in each forest stream must be correctly identified. At present, a large number of fish- bearing streams are not identified on stream classification maps. To correct this problem, the Oregon Department of Forestry ( ODF) and the Oregon Department of Fish and Wildlife ( ODFW) must complete comprehensive surveys to identify fish use on all non- federal forest streams in Oregon. This effort will require at least 3 to 5 years and a significant financial investment. Because many streams are not accurately classified, the new rules also tempo-rarily protect streams that are likely to contain fish. Under the rules, for example, if Stream A flows into a body of water known to contain fish, it is assumed that fish also are using Stream A, up to the point that a natural barrier blocks their way farther upstream ( see OAR 629- 57- 2100: ll( b) B). Once the survey efforts are complete, this interim rule will not be needed. Coordinated efforts by public agencies, landowners, and others to complete fish- presence surveys will assure that important fisheries resources are pro-tected in the most cost- effective way. Landowners or any interested party may collect stream- classification information so that the overall survey can be completed as quickly as possible. Many private forest landowners, in cooperation with Oregon Department of Fish and Wildlife, are now completing inventories of stream habitat conditions on their lands. In the future, these cooperative efforts may also include fish-presence surveys. This publication tells how to complete fish- presence surveys on forested streams. The guidelines cover: How to plan either " operation- specific" or " maximum upstream fish distribution" surveys The proper way to conduct surveys The proper time of year to conduct surveys Minimum efforts required in completing the surveys The legal requirements for completing the surveys How to provide information to Oregon Department of Forestry to update the stream classification maps The stream reclassification process Operation- specif ic surveys Maximum upstream distribution surveys Planning the survey There are two major types of survey: operation- specific surveys, and surveys to find the maximum upstream distribution of fish. Each type requires different planning and is conducted using different approaches. Operation- specific surveys are those to classify a stream only in the particular area of an operation. This kind of survey may not include efforts to determine the maximum upstream extent of fish use. An operation- specific survey takes minimal planning and coordination. However, it may be very inefficient in the long run because future activities in other areas of the stream may require additional surveys. An operation- specilk survey is very simple to complete. It starts at the down-stream end of the operation area and moves upstream either to the end of the operation area or to the end of fish distribution, whichever comes first. If the purpose of the survey is to prove no fish use, the surveyor must be sure to make at least the minimum effort required to find fish ( see the section on " Survey Effort" on page 10). This kind of survey is done on an entire stream reach or on multiple stream reaches rather than on a restricted portion of a stream. Often, all streams within a basin or reach are completely surveyed. In some cases, the surveys encompass entire ownerships or watersheds. The specific locations of planned operations are usually not the main factor in setting up this kind of survey but can help decide which areas to survey first. Surveys to find the maximum upstream extent of fish use may be the most efficient and cost- effective. Surveyors often cover a group of streams in one area at a time; therefore, travel time is minimized because, often, a group of streams can be easily reached by one common forest road. When travel time is less, the time spent actually completing surveys is greater. This kind of survey may require slightly more planning and coordination to assure efficiency and to minimize duplication of effort by adjacent landowners or by other public agencies, but overall this approach is more cost- effective than the operation-specific surveys. Surveying for the maximum upstream distribution of fish may take more plan-ning than an operation- specific survey, but it is still relatively simple. First, look at ODF Stream Classification Maps for the survey area to see the current extent of fish- use streams. Also note which streams are not classified at all. Next, decide where to start the survey. It may help your planning if you know the relationship between watershed basin area and fish use for your area. Contact the local ODFW office to find out whether these relationships have been established for streams in your area. The information predicts where fish use is " likely to end" and so will help you decide where to start your surveys. At this point, you also may want to consider operations that are planned for certain areas and decide to survey those areas first. After choosing a starting area, look at current road maps to find potential starting points for the survey ( see Figure 1). Look for access points ( such as road crossings) near the upper reaches of the stream. When possible, a survey should start near the highest accessible point in the watershed. If road access to the stream is limited, you may want to start the survey near the point at which the stream's classification size changes from " medium" to " small"; often this point is near the end of fish use ( see Figure 2, page 4). At the starting point, first sample upstream. If you find fish, continue the survey upstream until fish use ends. Be sure to continue sampling above the point at which fish use ends ( see " Survey Effort," page 10). If you make all the required efforts but do not find fish, then survey downstream from the original starting point until you find fish. When surveying downstream, it is important to walk on the streambank until you are ready to sample so that the water stays clear. Begin fish survey above road crossing Fish use extends at least this far Figure I . Selecting survey starting points in an area with a road crossing. Additional survey work may be required if the maximum distribution of fish seems to be affected by a road culvert. If the stream above the culvert has no fish, sample the pool immediately below the culvert. If you find fish in this pool or downstream near the culvert, the culvert is a possible barrier to fish passage. Describe the culvert and the stream on the survey form ( page 19). If you do not find fish in the pool below the culvert, continue the survey down-stream until you do see fish. Begin fish survey here \ \\ \ / I Fish use extends at least this far - - k I Figure 2. Selecting survey starting points, based on the stream- size classification, in an area without a road crossing. Surveys to find the maximum upstream distribution of fish may require sampling across several land ownerships. Be certain to get permission from other landowners before beginning the survey. Contacts with other landowners are also important to prevent a duplication of effort, because many landowners and agencies may be conducting fish- presence surveys. When figuring how many surveyors and how much time you'll need to com-plete surveys in your area, you may want to consider the Department of Forestry's experience. We found that sampling a township ( 36 square miles) required approximately 24 person- days in the Coast region, but an area the same size in the Blue Mountains required only 4 person- days. Survey methods The accuracy and reliability of survey results depend greatly on the methods used to conduct the survey. Methods range from simply looking in the stream ( visual observation) to more intensive and effective sampling with a backpack electroshocker. The method you choose depends on the availability of sam-pling equipment, the size of the stream, the flow and clarity of the water, and other factors. It is important to select a sampling method that is best for the type of survey and for the waters being sampled. If the sample method is not appropriate, the results of the survey will not be very useful. For example, just looking at a stream may tell you there are fish in it at that point, but it is not an acceptable way to find the maximum upstream extent of fish use. Surveys to show that fish are not present require more sampling and specialized equipment in order to provide reliable results. Whenever the survey uses methods other than an electroshocker, it's important to thoroughly explain on the survey report form the reasons for using the other methods. This is the simplest method; it involves only walking the stream to look for fish. It is best to wear polarized sunglasses to reduce glare from the water and to survey only when water conditions allow good visibility. It's also best to walk upstream so that you can " sneak up" on fish in pools. Fish often are near the upstream ends of pools waiting for food to drift toward them. Small fish, such as fry, often are in shallow water along the margin of the stream. Be very alert because fish usually will dart into cover when they detect any movement, especially in small headwater streams. It helps to toss bread crumbs, insects, small twigs, or bemes into the stream to entice the fish to leave cover. The visual method is best suited to small streams where pools aren't deep enough to prevent your seeing the fish. This method is also the least damaging to the fish because actual collection is not required. However, the value of survey results can be reduced by many factors such as cloudy water, surface glare on the water, overcast days ( reduced light), fish behavior, and even the surveyor's poor eyesight. For these reasons, this method is not effective for determining the maximum upstream limit of fish distribution, although it can be used to prove fish are in a certain reach of the stream. Snorkeling is a special method of visual observation that can work well in some situations. Snorkeling allows you to see underwater through a diving mask and breathing snorkel. This method can be used in larger waters where electroshockers are less successful, and it has been used to locate fry where other methods failed. Night snorkel surveys are particularly useful for observ-ing bull trout fry. Visual observation Hook and line Backpack electroshocker The hook- and- line method uses a rod and reel and relies on the feeding be-havior of the fish. In small streams, drop a baited hook into the deepest pools, where larger fish often are. Bait can include worms, single eggs, cheese, dry flies, or stream insects such as caddis larvae. Sample pools that have a lot of cover because those tend to support greater numbers of fish. As with the visual observation method, approach the pool cautiously to avoid alerting the fish. To minimize the risk of injuring or killing the fish, always use barbless hooks. The hook- and- line method can be used when conditions are not good for visual sampling; for example, when water is not clear, flow is high, or the day is overcast. This method may be the most effective for sampling some larger or deeper waters where visual and electroshocker methods can be ineffective. These waters include deep beaver ponds and large, steep streams where downstream barriers ( such as falls and very steep sections) keep fish out of the small tributaries. This method has limitations, though, depending on fish behavior and the life stage of the fish that are present. Fish may be reluctant to bite on cold days, or when the water is murky with sediment, or if the fish detect the surveyor's presence. Also, hook- and- line sampling is not effective if only fry are in the stream. This method also depends on the angling skills of the surveyor. As with the visual observation method, hook- and- line sampling may not be the best way to determine the maximum upstream distribution of fish in small streams, but often it can be used to find fish in larger waters. The most effective way to determine the upstream extent of fish is with a backpack electroshocker. Electroshocker sampling requires additional training and experience, though, to be effective and safe. A backpack electroshocker introduces an electric field into the stream that temporarily immobilizes fish. Stunned fish can be observed as they float in the water, or they can be captured in a small hand net for closer observation if necessary. As with other methods, it is best to work in an upstream direction, wear polarized glasses, and to approach the sampling site carefully to avoid alerting the fish. One person nets fish while another person operates the electroshocker. The netter should walk behind or beside the shocker to avoid alerting the fish. The electroshocker can be very effective for sampling in small streams even where brush or instream cover prevents most other sampling methods. In fact, an electroshocker is often most effective in areas with instream cover because fish usually concentrate in these locations. This method works in streams of various sizes but is less effective in larger streams and in deep pools, espe-cially large beaver ponds. Use electroshockers carefully to minimize killing fish. When properly adjusted and used, the electroshocker should stun the fish without killing them. The fish may escape if the current is set too low, but usually the surveyor will still see the fish and so be able to document fish presence. To sample effectively and minimize fish kill, set the electroshocker on the lowest practical voltage output and low- frequency currents ( low pulse rates). Before sampling, use a voltame-ter to test the electroshocker in a stream. If the voltameter is not available, it is a good idea to test the electroshocker in a stream that you know has fish before working in streams whose fish use you do not know. The test will tell you whether the equipment is working and the effects of using different settings. The surveyors' safety must be considered carefully before using this method. Electroshockers can injure or kill humans if not properly used. Surveyors should not use this method without proper training, including CPR training. Surveyors should work in crews of at least two. All surveyors should wear rubber waders and rubber gloves during stream shocking and never use dipnets with metallic handles; the nets should have wood or fiberglass handles. All members of an electroshocking crew should understand the proper operation procedures and potential dangers of this equipment. The effectiveness of electroshocker sampling depends on water conditions and on the skills of the electroshocker operator and the netter. The electroshocker method may not be so useful in high flows or in turbulent or murky water because the surveyors may not see immobilized fish. Another drawback to this method is that the electroshockers may not be widely available and can be expensive. However, with proper training and experience and under suitable survey conditions, this method is the best for accurately determining the maximum upstream extent of fish use. There may be situations where reliable results can be had by using methods not discussed here. For example, headwater beaver ponds may be effectively Other methods sampled by fishing for at least 48 hours with minnow traps baited with salmon eggs or commercial trout bait. Or, seine nets may be effective in beaver ponds or larger waters. If you are thinking about using these or other sampling methods, discuss it first with the departments of Fish and Wildlife and of Forestry. They will decide whether the proposed methods are appropriate and, if so, set the required minimum level of sample effort for the alternate method. A backpack electroshocker is the best way to get reliable information about the upstream extent of fish use or to prove a stream is m e N ( no fish use). Sur- Survey methods: vey data that document the presence of fish through other methods, such as a summary visual observation or hook- and- line, will always be used to classify streams as Type F as far up as the point of observation, even though the exact upstream extent of fish use may not be known. In some cases, methods other than an electroshocker may give reliable information about the maximum upstream distribution of fish. Examples include deep beaver ponds and large, steep streams in which barriers keep fish out of small upstream tributaries. In those cases, reliable results may be better obtained with hook- and- line sampling or with other methods. Whenever the survey is conducted by methods other than an electroshocker, the reasons for choosing the other method must be thor-oughly explained on the survey form. Timing the surveys Survey accuracy depends a lot on the time of year the survey is done and on stream conditions at that time. Since the purpose of the survey is to accurately document the presence or absence of fish, it is critical to do the survey when fish are expected to be using the upper reaches of a stream. This generally is near spawning times or soon after fry emerge, when stream flows are relatively high. A survey done during a low- flow period may not indicate the actual maximum upstream extent of fish use or accurately prove no fish use the stream. Fish may use the upper reaches of a stream for a limited time only, so fish- use surveys must be timed carefully. Surveys done at other than recommended times may not give a complete description of fish use. For example, if fish are found at other than the recommended survey times, the surveyed part of the stream can be classified as fish- bearing, but the maximum upstream extent of fish use may not be known. If fish are not found, that will not necessarily prove that the stream reach does not support fish use. Only if the survey is made at a time when fish are most likely to be there can the absence of fish be a reliable sign that no fish use that portion of the stream. Other factors can affect the reliability of the survey even if it is made at the proper time. Abnormal flows due to drought or extreme runoff could affect the distribution of fish or the sampling efficiency of the surveyor. So, it is best not only to do the sampling within the recommended time period but also when conditions are appropriate. In some cases, survey timing may not have much effect on the reliability of survey results. This could occur when factors other than seasonal flow patterns control the upstream extent of fish distribution. For example, streams that get most of their water from springs may not have seasonal flow variations, including summer flows low enough to control the upstream distribution of fish. Or, conditions other than low flow could be controlling distribution. For example, large, steep streams that have natural barriers such as falls and steep, impassable sections. In such cases, surveys taken outside the recommended time periods may yield reliable data. However, it is important to describe these conditions thoroughly on the survey forms to justify not following the recom-mended timing. See Table 1 for the recommended sampling periods for different regions of the state for normal water- flow years. Periods differ due to variations in stream flow patterns, fish species, and life- history traits of the species in the different areas. Contact the local ODFW office before sampling to find out the best time to survey the stream you are planning to sample. Table 1. General recommended time periods to sample streams, by geographic region, during nomull water- flow years. Please contact your local ODFW ofice before sampling in order to get specific timing recommendations for the stream you will be sampling.

Contact the local ODFW office before sampling to get specific timing recommendations for the streams to be surveyed. Information gathered at other times of the year may be used to document fish presence but may not be reliable enough to establish upstream fish- use limits or to classify the stream as II) lpe N ( no fish use). Whenever the recommended survey timing is not used, it is important to explain the reasons on the survey form so that the data can be evaluated for reliability. ~ - ~ Survey timing: a summary Survey effort: a summary Survey effort The level of effort used to complete the survey also can affect the reliability of the survey results. If the level of effort or the amount of stream sampled is too little, it may be wrong to conclude that fish are not present. The following guidelines describe the minimum level of survey effort required to assure that the data are reliable. If the purpose of the survey is to show that no fish use the stream, the survey will be considered reliable only if it includes at least 50 yards of stream length md a minimum of six pools, each at least 1 foot deep, immediately upstream of the point at which the non- fish- bearing section begins. ( In some cases, the survey will have to cover much more than 50 yards of stream in order to also include the required six pools.) In addition, the survey must include sampling any beaver dam ponds in the upstream non- fish section. Surveyors are encouraged to exceed the minimum level of effort in order to be even more sure that fish are absent from a stream reach and that the maximum upstream extent of fish use has been found. A survey intended to show the absence of fish must sample at least 50 yards of stream distance and a minimum of six pools, each at least 1 foot deep, imme-diately upstream of the point at which fish use is believed to end. In addition, any beaver ponds upstream must be sampled as part of the survey. The require-ments for the methods used and the timing of the survey also must be met in order to document the absence of fish. Legal requirements In Oregon, the Department of Fish and Wildlife regulates the collection of fish for personal or scientific use. Generally, collection methods prohibited by the general angling regulations, such as electroshockers, traps, or nets, and collec-tions at times of the year when angling is closed will require a Scientific Collection Permit from the Oregon Department of Fish and Wildlife. Scientific Collection Permits can be issued to agencies, companies, or indi-viduals. Request an application from the Fish Division of the Oregon Depart-ment of Fish and Wildlife, P. O. Box 59, Portland, OR 97207; telephone ( 503) 229- 5410, extension 323. Submit the application at least 1 month before you plan to do the survey in order to be sure the permit can be issued in time. The application requests information about the collection method to be used, when and where collection will be made, and a summary of the proposed project. By law, surveyers must keep records of their collection activities and submit them to the Oregon Department of Fish and Wildlife. Surveys using the visual observation method ( including snorkeling) do not require any licenses or permits because fish are not physically collected. Sampling with the hook- and- line method during open fishing seasons requires only a valid angling license. However, Oregon resident landowners and their immediate families do not need angling licenses to fish on land they own and live on. In either case, the general ahgling regulations for the stream must be followed during hook- and- line sampling unless a Scientific Collection Permit is obtained. Additional restrictions on survey efforts may apply if the stream contains species that the state or federal government lists as sensitive, threatened, or endangered species. Please contact your local ODFW office to find out whether any of these species are likely to be in streams you plan to sample. Reporting survey results Give survey data to the local ODF district office so that district Stream Classi-fication Maps can be updated. On page 19 is a blank survey report form. It asks for information about the location of the stream; the methods, timing, and effort of the survey; the physical character of the stream; observations of fish and wildlife; and the presence of natural or human- created barriers to fish passage. complete one form for each stream reach where fish were ob-served or fish use was found to end. See Figure 3 ( page 12) for descriptions of some fish species common to $ mall, forested streams; these may help to identify fish seen during surveys. Detailed instructions for completing the survey form are on pages 14 through 18. Attach to the Fish Presence Survey Form a copy of the ODF Stream ClassM-cation Map for the surveyed area or, if that is not available, a copy of the 7.5 minute USGS topographic map for the area. Note the following information on the map. ( Examples of completed survey report forms and maps are on pages 21 through 30.) The area of the stream that was actually surveyed ( including the areas without fish) as part of the survey effort. Highlight in yellow the entire stream reach surveyed ( see examples on pages 25,28, and 30). The upper limit of fish use. Note this on the map by drawing a line across the stream and writing the letter F at that point. The name of the surveyor. The date the stream was surveyed.

All affected landowners will be notified of the proposed stream classifica-tion changes, according to the notification rules ( OAR 629- 57- 2110( 2)). Instructions for completing the survey report form The following information should be reported on the Fish Presence Survey Form. These instructions are in the order that the information appears on the form. Complete one form for each stream reach or branch where fish were observed or fish use was found to end. This may require assigning codes to unnamed tributaries ( for example, " trib. a," " trib. b") so that survey data can be cross- referenced to the survey maps. Please refer to examples on pages 21 through 29. Surveyor Narne( s): The name of the person or persons responsible for con-ducting the survey and reporting the results. AgencyfCompany: The name of the agency or company that employs the surveyor ( if applicable). Landowner: The name of the landowner of the reach surveyed. Mailing Address and Phone: The address and phone number for the person responsible for the survey. Stream: The name of the stream as reported on the USGS or ODF Stream Classification Map for the area. If the stream is unnamed, report the stream as " unnamed" and list the tributary that it flows into (" Tributary to..."). Tributary to: The name of the main stream ( as reported on the USGS or ODF map) that the surveyed stream flows into. This is especially important if the surveyed stream is unnamed. Quad Map: The name of the USGS 7.5 minute topographic map that includes the reach of the stream surveyed. If the surveyed reach covers more than one quad map, report first the name of the map that shows the identified end- point of fish use and then give the other maps' names. Location: A legal description ( township, range, and section to at least the quarter section) of the location where fish use ends. Date Surveyed: The month, day, and year the fish survey was conducted. Survey Method: Check the box for the survey method used. If more than one method was used, check all that apply and note the most often used method in the comments section or in the form's margin. Survey Amount Above End of Fish Use: The length of stream reach that was surveyed immediately upstream of the identified end of fish use. Estimate ( in feet) the length surveyed, and give the number of pools sampled for fish in that section. A survey to prove the absence of fish must sample at least 50 yards of stream and at least six pools immediately upstream of the end of fish use. In addition, any upstream beaver ponds must also be sampled. Flow Level: The flow conditions at the time of the survey. Use the following categories of flow. Low: Ranges from a series of isolated pools to flowing across less than 75 percent of the average bankfull width. Moderate: Surface water is flowing across 75 to 90 percent of the average bankfull width. High: Surface water flowing across more than 90 percent of the average bankfull width. It is not recommended thatfih presence surveys be conducted at high jlows. Weather: The weather during most of the fish survey ( rainy, overcast, partly cloudy, sunny, snowy, etc.). Water Clarity: The water visibility during the survey. Use the following categories of water visibility. Clear: Visibility is good in pools, deep pools, and riffles. Moderate: Visibility is good only in riffles and shallow pools. Turbid: Visibility is poor in both riffles and pools. It is not recommended that fih presence surveys be conducted when water is turbid. Water Temperature ( optional): The temperature of the stream ( in degrees Farenheit) at the time of the survey. Fish observations Report the species and approximate size ranges of fish observed in the sur-veyed reach. Use Figure 3 ( page 12) as a guide to identifying some game fish species commonly found in small, forested streams. Use the following codes and instructions to complete this section. Species: Use the following names or codes to report fish observed during the survey. If you observe a species not listed here, such as Pacific lamprey, use its common name. Name Species Code Coho salmon Co Cutthroat trout Ct Rainbow troutfsteelhead Rb/ St Bull trout BUT Brook trout BT Unknown salmonid UnS Sizes: Report the size range of fish, in inches, by species. For example, the size range of coho observed could be reported as " 1- 4 inches." If you see several sizes of one species ( for example, some cutthroat trout in the " 1- to 2- inch range and others in the " 6- to 8- inch" range), list them separately. Aquatic wildlife The types of aquatic wildlife that may be observed include tailed frogs ( includ-ing juvenile " tadpoles"), Pacific giant salamanders, and Olympic salamanders. Species: Give the common name of the species, if known. If you don't know the species name, at least report observations by a general name such as " salamanders." Number: The number of aquatic wildlife in each species or group observed. Physical stream data Report the physical characteristics of the stream in the vicinity of the end- point of fish use. Report information separately for ( 1) the section immediately at and downstream of the end of fish use, and ( 2) the area upstream of the maximum extent of fish use. Following are specific instructions for collecting this information. Bankfull Channel Width: By eye, estimate the average width ( in feet) of the bankfull channel for the 100- foot sections above and below the end- point of fish use. The bankfull channel is the area that is scoured by water during average high flows. The edge of the bankfull channel can be identified by looking for changes in vegetation, in soils and litter characteristics, or in the shape of the bank. The bank often will abruptly change slope at the bankfull boundary. Vegetation at the boundary often changes from annual vegetation ( such as grasses) to more permanent vegetation such as trees and shrubs. Estimate the width across the channel between the edges of the bankfull level. Current Wetted Width: Visually estimate the average width ( in feet) of the channel that contains flow ( is wetted) at the time of the survey. Report the estimated averages for the 100- foot sections above and below the end of fish use. Channel Gradient: Measure the average stream gradient with a clinometer for the 100- foot sections above and below the end of fish use. me a piece of flagging at eye level on a branch or shrub, walk up or down the stream bank, and then use the clinometer to sight on the flagging while you are standing on the channel bottom. Read and report the percent gradient. ODF Stream Class Size: The stream size (" small," " medium," or " large") from the ODF Stream Classification Maps for the reaches immediately above and downstream of the end of fish use. Natural barriers This information is very important for understanding relationships between the presence of fish and the physical characteristics of the stream. Understanding these relationships can help determine where fish- presence surveys should be concentrated and help predict where fish are likely to occur if survey informa-tion is not yet available. Generally, natural barriers are permanent structures such as falls or vertical drops more than 8 to 10 feet high for salmon or steel-head or 4 feet high for trout. Log jams, drops over logs, beaver dams, or other organic structures generally are only temporary barriers to fish passage, but report them as well. If fish use ends at a natural barrier, such as a waterfall, bedrock chute or cascades, describe the conditions at the site. Include a description of: ( 1) the type of barrier, ( 2) the approximate height ( in feet), ( 3) the percentage of slope, ( 4) the length ( in feet) of the bedrock chute or cascades, and ( 5) any other conditions that may be limiting fish passage. If the potential barrier is a bedrock chute, note whether the bedrock contains pools or rough features ( such as rocks, boulders, or other breaks in the flow), or whether the water flows in an even, shallow pattern over the bedrock. Please note on the survey map the locations of any natural barriers encountered. If you encounter a natural barrier, also be sure to sample above this point because fish often are found above natural barriers. Road- crossing barriers This information also is very important for understanding relationships be-tween the presence of fish and the physical characteristics of the stream. Road-crossing barriers can alter the relationships. If fish use ends at a road- crossing barrier, such as a culvert, describe the conditions at the site. Describe the type of barrier and its measurements at the time of the survey such as ( 1) the diameter of the culvert, in inches, ( 2) the depth ( in inches) of water in the culvert, ( 3) the height ( in feet) of the jump ( drop) below the culvert or structure, ( 4) the depth ( in inches or feet) of the plunge pool below the culvert outfall, ( 5) the gradient or slope of the culvert, given as a percentage as read off a clinometer, ( 6) the length ( in feet) of the culvert, and ( 7) any other factors that could affect fish passage. Please note on the survey map the locations of any road- crossing barriers, even if they are not at the end- point of fish use. As with natural barriers, be sure also to sample above the site because fish often are found above road- crossing barriers. Other comments Any other comments or notations that you think may be pertinent to the fish survey. It helps to describe any notable habitat characteristics, for example " lots of instream wood," " very few pools in the reach," " heavy silt load in the stream."

1 i California Oregon Cover Photo: Lower Klamath National Wildlife Refuge at sunset Tupper Ansel Blake/ USFWS Map Detail Area: Upper Klamath River Basin ii T he Klamath River Basin presents numerous challenges as well as opportunities for its many water users. For years, farmers and ranchers in the basin have recognized the vital role they play in the health of their watershed. Working with conservation districts, the Natural Resources Conservation Service ( NRCS) and others, land managers continue to proactively find ways to enhance natural resources in the basin, benefiting wildlife and the environment. However, as it has across the western United States, drought hit home in the Klamath for those who depend on every drop of water to sustain their livelihood, culture and community. In the spring of 2001, the combination of drought and the impact of the Endangered Species Act triggered a shutdown of irrigation water during the growing season, drying up water resources to more than 2,000 farms and ranches. NRCS, in cooperation with local conservation districts, provided a quick infusion of technical assistance and $ 2 million in cost- share funding for cover crops through the Emergency Watershed Protection Program. As cover crops took hold, the seeds of a long- term solution took root in the NRCS/ conservation district partnership. The ability of the local office to receive funding, engage community members and other partners, plan resource improvements, implement actions, and monitor success proved to be an invaluable asset for the community. Helping private landowners develop and apply practical, common- sense solutions to complex resource issues will be the challenge of the conservation partnership well into the future. USDA, in concert with the locally led conservation districts, will continue to play a critical role by delivering technical and financial assistance to Klamath Basin farmers and ranchers. The Rapid Subbasin Assessments that follow are the first step in that process. The assessments are designed to help local decision- makers determine where investments in conservation will best benefit wildlife habitat, agriculture and other land uses in a compatible manner. It is our goal to provide a comprehensive overview of resource challenges and opportunities in the basin, and help decision- makers to prioritize their investments in areas that will best sustain multiple use of natural resources in the basin now and in the future.

Stretching across southern Oregon and northern California, the Klamath Basin has become synonymous with the water challenges that western water users face. As one example, agricultural commodities that need irrigation water to thrive – providing Americans with the cheapest domestic food supply in the world, face competition from the critical water needs of sucker fish, salmon and other threatened and endangered species. While that competition is understandable, more and more, conservation leaders in all industries have come to recognize that these water needs aren’t necessarily at odds with one another, and can in fact be compatible. While an example of the challenges today’s agricultural producers and conservationists face, the Klamath Basin has emerged as an example of how diverse interests can work together successfully. 2 Overview of the Upper Klamath Basin Upper Klamath Basin Description The Upper Klamath Basin is an area of high desert, wetlands, and the Klamath River. The river extends 250 miles from its headwaters at Upper Klamath Lake in south central Oregon to the west coast of northern California. The Upper Klamath Basin includes the US Bureau of Reclamation’s ( USBR) Klamath Project Area and the drainage area above Irongate Dam on the Klamath River. The basin’s lakes, marshes, and wetlands host an abundance of plant and animal species and include national wildlife refuges, parks, and forests. Agricultural production began around the turn of the 20th century, and with the creation of the Klamath Irrigation District in 1905, water diversions for irrigation began in earnest. A portion of these irrigated lands are in the USBR’s irrigation project. The ‘ project area,’ as it is commonly called, includes 188,000 of the 502,000 acres of private irrigated land in the basin. This includes lands leased from the various wildlife refuges that are supplied with water by the USBR. Privately irrigated acreages can vary from year to year, depending on USBR contracts and annual cropping cycles. In comparison, the majority of the private irrigated land - about 314,000 acres - in the basin is located outside the project area. Upper Klamath Basin Quick Facts: • Over 2.2 million acres are privately owned in the Upper Klamath Basin • 188,000 of the irrigated acres are in the US Bureau of Reclamation’s Irrigation Project • Approximately 502,000 acres of privately owned lands are irrigated • 314,000 acres of irrigated lands are outside the Project area 3 Overview of the Upper Klamath Basin The Role of Agriculture in the Basin Agricultural lands play a key role in a healthy ecosystem. Located on the Pacific Flyway, migratory birds like the American White Pelican and the Red- Necked Grebe use croplands in the Klamath Basin as an important feeding and resting stop. Deer graze on wheat and barley fields, and pheasants use both crop and rangelands for their nesting and feeding grounds. Progressive conservation leaders recognize that farming and fish and wildlife habitat are not mutually exclusive. Well- maintained farmland creates fish and wildlife habitat, contributing to a healthy watershed. They also recognize that opportunities will always exist to improve the condition of natural resources in the basin. To address those opportunities, conservation leaders in Oregon’s Klamath Falls Soil and Water Conservation District and California’s Lava Beds/ Butte Valley Resource Conservation District have proactively identified four key priorities tied to natural resource conservation. The districts asked experts at the USDA’s Natural Resources Conservation Service to help them develop a plan to determine what could be done on- farm to conserve water, increase water storage, improve water quality, and enhance fish and wildlife habitat. While so much of the attention to date in the Klamath Basin has been focused on water demand, these conservation leaders recognize demand is only one piece of the puzzle. Comprehensive solutions must also address water quality, storage and wildlife habitat. Conservation District Priorities 1) Conserve Water 2) Increase Water Storage 3) Improve Water Quality 4) Enhance Fish & Wildlife Habitat 4 Rapid Subbasin Assessments Conserving natural resources is the ultimate goal throughout the basin, and its success hinges on long- term solutions. At the request of local conservation districts, NRCS undertook an 18- month study of resource concerns, challenges and opportunities throughout the Upper Klamath Basin. The study was not intended to provide a detailed, quantitative analysis of the impacts of conservation work, but rather, to provide an initial estimate of where conservation investments would best address the districts’ four priority resource concerns. Beginning in the spring of 2002, NRCS planners collected information to enable the conservation districts, agencies, organizations, farmers, ranchers and others to make informed decisions in a timely manner about conservation and resource management in the basin. These Rapid Subbasin Assessments are intended to help leaders set priorities and determine the best actions to achieve their goals. As a part of the rapid subbasin assessment process, eight subbasins were delineated ( see map at left). A watershed planning team traveled through each subbasin, inventorying agricultural areas, identifying conservation opportunities and current levels of resource management, and estimating the impacts of these opportunities on the Conservation in the Upper Klamath Basin 5 Conservation in the Upper Klamath Basin conservation districts’ priority resource concerns. They focused their recommendations on areas that would provide the best benefit to the wide array of stakeholders in the Upper Klamath Basin. They also identified a number of socio- economic factors that must be taken into consideration when helping producers adapt to new management styles and conservation activities. Through NRCS, conservation districts and other federal, state and local entities, private land managers are working to identify ways they can more efficiently use – and share – the water they need. In the face of increasingly complex and politically polarized circumstances, a clear purpose and direction has arisen. The commitment of the local conservation partnership to identify the impacts of water shortages and to find solutions that will improve natural resource conservation will be key to the long- term viability of both endangered species and industries in the Upper Klamath Basin. The information that follows provides a summary of the conservation challenges and opportunities that NRCS staff found in their assessment. Recommendations for where financial and other resources can best be invested to improve natural resources, while sustaining the economy of the Upper Klamath Basin, are also identified. 6 Conservation in the Upper Klamath Basin Private Lands Conservation Accomplishments One component necessary to understanding future conservation opportunities in the basin is to recognize the current conservation work of private land managers. An indicator of these efforts is the work that has been undertaken in partnership with NRCS and the local conservation districts. In federal fiscal years 2002 and 2003, Upper Klamath Basin farmers and ranchers improved resource conditions on 18,877 acres of privately owned agricultural lands, with assistance from NRCS and the conservation districts. During this time, private land managers have worked with the conservation districts in the basin to: • improve the condition of 11,800 acres of grazing lands • conserve water and improve water quality on 13,656 acres • restore and establish 4,138 acres of wetlands and riparian areas • improve 281 acres of forest stands • establish resource management systems on 1,351 acres of cropland These conservation efforts were accomplished with a combination of private, state and federal funding. 7 Conservation in the Upper Klamath Basin Summary of Conservation Opportunities In addition to recognizing current conservation activities, the assessments define what can be accomplished with a strong conservation partnership in the Upper Klamath Basin. All too often, the debate about multi- use of water in the basin has focused on ways to reduce water demand. However, the basin’s many water users - including fish and wildlife - benefit just as much from improvements to water quality, water storage and wildlife habitat. Taken together, the recommendations that follow seek to utilize a comprehensive approach to all four resource priorities - with the goal of contributing to a sustainable, multi- use water system. While quantification of the results of conservation work in these four areas is difficult, there is no question that a comprehensive approach to natural resource improvement in the Upper Klamath Basin will result in accumulative long- term benefits for endangered fish species, wildlife habitat, agriculture, urban and other water uses. Agriculture cannot undertake these efforts alone. Private landowners and the general public both benefit from natural resources conservation in the Upper Klamath Basin. Because of this, public and private sources of funding from in and outside the region are necessary. Solutions of this magnitude also come with other social, political, and cultural costs. Upper Klamath Basin Quick Facts: • 1,400 farm families live in the Upper Klamath Basin • The Upper Klamath Basin is home to sucker fish, bull trout and redband trout 8 Conservation in the Upper Klamath Basin For example, all stakeholders in the Upper Klamath Basin need to identify and address social, economic, and cultural resource- based values they have historically enjoyed. Politically, there must be resolution and agreement on water rights, endangered species, and water quality. Water Conservation Because few water use measurements have been taken in the past, it is difficult to quantify where specific water efficiencies can be gained. Throughout the Upper Klamath Basin, water that leaves one irrigated field generally re- enters streams or enters the groundwater, providing the opportunity for it to be utilized again later. Because of this, water delivery systems both in and outside the USBR project area are generally efficient. As a result, the most significant benefit of reducing water demand on individual farms is an improvement in water quality and reduction in water temperatures, rather than an increase in available water. 9 Conservation in the Upper Klamath Basin Conservation measures that reduce water demand on private agricultural lands can be accomplished in a variety of ways. New technologies for managing when and where water is applied on crop and pasture lands will help to ensure that water is only applied when it is of the best benefit to the plant. Water conservation opportunities include improving irrigation water-use efficiency, retaining and conserving drainage water, and making use of new technologies that more accurately forecast the impacts of drought and floods. The subbasin assessments indicate an opportunity to conserve water and improve water quality on 130,000 acres of irrigated lands within the USBR project. Outside the project area there is an opportunity for water conservation on approximately 220,000 irrigated acres. If all potential conservation practices are implemented on all irrigated lands, on- farm water use efficiency could increase by up to 25 percent in the Upper Klamath Basin. A potential two to five percent increase in water yield could be achieved by increasing management in upland range and forestland areas. In all cases, these are preliminary estimates and require validation. This estimate does not account for evaporation, transpiration, seepage or other loses that may occur at the sites receiving conserved water nor does it evaluate irrigation delivery or conveyance efficiencies. Tupper Ansel Blake/ USFWS 10 Conservation in the Upper Klamath Basin This level of water conservation cannot be reached without a concerted federal/ state/ private partnership that works together to apply water conservation practices in targeted areas throughout the Upper Klamath Basin. Improving Water Quality Water quality has a direct impact on many fish and wildlife species. Within the Upper Klamath Basin, most rivers and lakes do not meet federally mandated Clean Water Act standards for temperature, dissolved oxygen, pH, or other pollutants. Water quality is affected by water temperature, low in- stream flows and the condition of adjacent land riparian areas, among other items. Private landowners are just one of many groups who have an opportunity to improve water quality throughout the basin. Water quality improvement opportunities on private agricultural lands in the basin range from improving the management of livestock near streams and rivers to utilizing new technologies that track pest and weed cycles to ensure that pesticides are only applied when they will be most effective. Water conservation practices that reduce tailwater runoff from irrigated fields can provide extensive improvements in water quality. 11 Conservation in the Upper Klamath Basin Increasing Water Storage/ Yield In recent years, drought has been a large contributing factor to reduced water levels in the Upper Klamath Basin. One solution to address low water flows would be to store water for times of water shortage. There are at least two challenges to this solution: finding a place to store water and finding water to store. To evaluate this option, potential storage values were calculated for 41 years of record from 1961 to 2002. This analysis reinforced the observation that, as has been seen in recent years, drought years normally occur in a multi- year cycle. Because of this, in the years where extra water is most needed, it is often not available from previous years to store. One promising, small- scale, water storage solution may lie in subsurface irrigation water storage in suitable locations, such as the Tulelake Subbasin. In this scenario, there exists a potential to store water in the soil profile and reduce irrigation water demand during the irrigation season. Another option for subsurface storage of water includes the restoration of streams and their surrounding wetlands and riparian areas. This can increase the “ sponge” effect allowing for the slow release of water through the long, dry summer months. Tupper Ansel Blake/ USFWS 12 Conservation in the Upper Klamath Basin Enhancing Fish and Wildlife Habitat The Upper Klamath Basin is home to a wide variety of aquatic and terrestrial species of wildlife and fish. Much of the water used in the Klamath wildlife refuges and associated marshes, ponds, streams and wetlands originates in the Upper Klamath Lake Subbasin. The Klamath Basin wildlife refuges provide a stopover for 85 percent of the ducks, geese, and other birds that migrate through the Pacific Flyway from Alaska to South America. Streams in the Upper Klamath Basin provide spawning and rearing habitat to threatened and endangered suckers and bull trout, as well as redband trout, which is listed as a species of concern by the US Fish and Wildlife Service. Several streams are highly valued “ catch and release” sport fisheries. There is high landowner and public interest in restoring and maintaining riparian habitat along these streams. Many of the conservation opportunities outlined under water conservation and water quality provide direct benefits to fish and wildlife as well. In addition, creating and restoring wetland areas, planting trees and developing wildlife habitat along the edges of crop fields all contribute to enhancing wildlife habitat in the basin. Tupper Ansel Blake/ USFWS 13 Conservation in the Upper Klamath Basin Overview of Conservation Effectiveness In order for the Upper Klamath Basin to successfully move forward with solutions, agriculturists, environmentalists, Tribes, government agencies, organizations, and others need to develop unified leadership to arrive at a common vision for the future. In addition, stakeholders and others must commit to a long- term investment of public and private funding as well as other resources. Based on the Upper Klamath Basin Rapid Subbasin Assessments, the Oregon and California NRCS planning staff rated the potential benefit of recommended conservation practices and resource management systems based on the conservation districts’ four resource priorities. Many state and federal agencies have invested in conservation work throughout the basin. While the recommendations in this document focus on private land and agriculture, the assessments can also be applied to help prioritize conservation practices on other land uses basin- wide. Overall, based on the planning team’s analysis, conservation activities in the Sprague River Subbasin would produce the greatest benefit, and conservation practices in the Upper Klamath River East Subbasin would yield the least Tupper Ansel Blake/ USFWS overall benefit based on the conservation district’s priorities. 14 Conservation in the Upper Klamath Basin While recognizing that any science- based conservation focus in the Upper Klamath Basin would be beneficial, the charts on pages 18- 19 specifically focus on work that can be accomplished on private lands. They provide a breakdown of recommended conservation practices on each of the conservation districts’ priorities by subbasin. For example, the water demand chart shows that investing in conservation practices in the Sprague River Subbasin has the greatest potential for reducing agriculture’s water demand by implementing improved irrigation practices. The Sprague also provides the best opportunity to address water quality and wildlife habitat. Investment in conservation activities in the Tulelake and the Upper Klamath Lake subbasins offers the greatest potential to address water storage/ yield. Investing in Conservation: Enabling farmers, ranchers and other private land managers to successfully address the four resource priorities will require: • The adoption of conservation on 350,000 acres of private farmland, range, and forests, • Financial resources estimated at $ 200 million for installation and another $ 27 million annually to operate, and • Twenty or more years to complete with the current financial and technical resources available.

Based on research completed by NRCS planning staff, the greatest potential to enhance water storage and yield occurs by implementing riparian/ wetland, forest and range conservation practices in the Upper Klamath Lake Subbasin. In comparison, the Tulelake Subbasin gains water yield through agronomic practices like subsurface drains to allow for winter irrigation. Overall, implementing forest and range practices in most subbasins will result in greater water yield within the soil profile and water table. Comparative Benefit: Habitat/ Fish Survival The chart at right provides an overview of the comparative benefit by subbasin of various conservation practices that improve wildlife habitat and fish survival. Based on research completed by NRCS planning staff, the greatest potential to improve habitat is in the Sprague Subbasin, using wetland/ riparian, forest, range and irrigation practices. In comparison, no measurable habitat benefits are achieved by implementing additional conservation practices in the Middle Lost River, Tulelake, Butte Valley or Upper Klamath River subbasins. Conservation in the Upper Klamath Basin 17 Tim McCabe/ NRCS 18 The Sprague River Subbasin is located 25 miles northeast of Klamath Falls and covers approximately 1.02 million acres. Forested mountain ridges enclose the Sprague River Valley, which includes large marshes, meadows and irrigated pasture. Juniper and sagebrush steppes dominate rangeland. Irrigated Pasture is the predominant land use in the Sprague River Valley. Approximately 65 percent of the water used for irrigation is diverted from streams, and 35 percent is pumped from wells. Flooding is the most common form of irrigation. Most diversions do not have fish screens and lack devices to measure water deliveries. Overall irrigation application efficiencies are low. Private forest and rangelands in the Sprague River subbasin are generally used for livestock grazing. Most forest stands are significantly overstocked with trees, and rangeland has been heavily encroached by Western Juniper. Pasture condition is generally poor to fair. The riparian areas within pastures have little to no riparian vegetation and high, eroding banks. Wildlife habitat in most of the upper reaches of the Sprague River and its major tributaries appears to be fairly stable, indicating good watershed condition. However, there are considerable habitat improvements that can be made in the lower portion of the basin. Sprague River Subbasin Water & Wetlands: 2,949 Range: 137,869 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 240,050 Sprague River Subbasin Agricultural Land Use/ Cover 19 Resource Concerns Water quality is the major resource concern in the Sprague River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. Lost River and shortnose suckers, interior redband and bull trout are key fish species present in the subbasin. All species are listed as Endangered Species Act threatened, candidate, or species of concern. The Sprague River has been identified as an important stream for both spawning and rearing habitat for suckers. Loss of riparian habitat, fish entrapment and fish migration impediments have also been identified as resource concerns in the Sprague River Subbasin. Conservation Accomplishments In the Sprague River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved the condition of 2,153 acres of grazing land, improved irrigation water management on 903 acres of irrigated land, and have restored 1,644 acres of riparian and wetlands areas. Fencing and riparian area restoration has been initiated or installed by private land managers with assistance from NRCS, US Fish & Wildlife Service and others on approximately 50 miles of stream and several thousand additional riparian and wetland acres. Sprague River Subbasin Land Ownership Private Lands 448,200 Public Lands 573,100 Total Land Area: 1,021,300 Irrigated Acres USBR Project: 0 Non- USBR: 61,600 Total: 61,600 20 Conservation Opportunities Water Quality & Wildlife Habitat: Riparian restoration can be accomplished by converting pastures to permanent riparian wildlife lands or establishing riparian vegetation. Riparian pasture units should be managed as a part of an overall grazing plan with cross- fencing and off- stream water for livestock. Forest stands should be managed to ensure optimum health of both the trees and grazed understory. Thinning overstocked trees and controlling juniper on rangelands are both effective management opportunities. Water Demand: Irrigation water management, including measuring water use and scheduling irrigation will help managers to maintain base river flows through late summer and early fall. Efficiencies can also be gained by leveling land, lining or piping irrigation ditches and incorporating tailwater recovery systems. Conversion from flood to sprinkler irrigation is also beneficial.

Combined, the Williamson and Sprague River subbasins make up 79 percent of the lake’s total drainage area. The Winema National Forest and Klamath Falls National Wildlife Refuge account for most of the public land in the subbasin. Irrigated pasture is the dominant private agricultural land use. Pasture is almost entirely flood irrigated. Ninety percent is diverted from streams, while groundwater supplies ten percent. Most diversions do not have fish screens and lack devices to measure water deliveries. Although overall irrigation application efficiency is low, additional water in the water table helps to subirrigate pastures. In addition, the proximity of these pastures to rivers and streams allows most excess diverted water to return to the system for reuse. Private forest and rangelands make up most of the private land in the basin. Approximately 80 percent of forestlands are used for grazing. Private forestland is in poor to fair condition; over half of the stands are significantly overstocked with trees. Wildlife habitat has faced considerable degradation in the past. Of the 48 miles of stream that are degraded in the subbasin, restoration efforts have been initiated on approximately 23 miles. Williamson River Subbasin Water & Wetlands: 19,700 Range: 2,600 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 225,300 Williamson River Subbasin Agricultural Land Use/ Cover Irrigated Alfalfa: 1,100 23 Water quality relating to elevated stream temperatures is a major resource concern in the Williamson River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. In 1988, when the Lost River and Shortnose suckers were listed as endangered, the Williamson and Sprague River runs were estimated to have declined by as much as 95 percent during the previous twenty- year period. Important sucker habitat has diminished by nearly 50 percent in the lower reaches and near the mouth of the Williamson River. This has reduced the amount of larval sucker spawning and rearing habitat. Conservation Accomplishments Significant conservation progress has been made in this subbasin. Land managers have improved 500 acres of grazing lands, 1,000 acres of irrigated lands, 235 acres of forestlands and have restored 112 acres of riparian and wetland areas. Heightened landowner awareness of resource concerns and increasing agency, organization, and individual efforts will help this trend to continue. Of the 48 miles of stream that are degraded in the subbasin, private land managers are working with the US Fish and Wildlife Service and others to restore 23 miles. The Nature Conservancy is restoring approximately 3,200 acres of wetlands, and plans to restore another 3,411 acres at the mouth of the Williamson River.

This can be accomplished by converting lands from irrigated agriculture to wildlife habitat or creating riparian pasture systems. Wetland and riparian areas still utilize water. However, this work may reduce total water demand depending on how lands are managed. Water Demand: Thinning forest stands and managing grazing areas by adding cross fences and off- stream water for livestock can yield more water to meet downstream needs. This will also result in enhanced wildlife habitat and improved water quality in area streams. In addition, forest stand improvements reduce the potential for catastrophic fire.

Historically, some 43,000 acres of wetlands surrounded Agency and Upper Klamath Lake. Today, 17,000 acres have been preserved as part of the Upper Klamath Lake National Wildlife Refuge. Another 11,000 acres have been acquired for restoration. Irrigated agriculture is primarily pasture. Livestock are generally stocker cattle, who graze between April and November. Pasture condition is generally fair. Most livestock obtain water from streams and ditches. Irrigation water is diverted from streams or pumped from the lake. Most diversions do not have fish screens or devices to measure water. Although overall irrigation application efficiency is low, the additional water raises the water table and subirrigated pastures. Some acreages of hay and cereal crops are grown, and irrigation efficiencies are higher than for pasture. However, most require maintenance and re- leveling. Forestlands are primarily pine and mixed fir and hemlock. Most private lands in the subbasin are forest or rangelands, with approximately 80 percent used for grazing. More than half of the forest stands are significantly overstocked with trees. Wildlife habitat varies in condition. Of 70 total miles, 21 miles of streamside riparian areas are in good condition and another 12 miles are being restored. Upper Klamath Lake Subbasin Water & Wetlands: 76,568 Range: 2,404 Irrigated Pasture/ Grass Hay: 48,856 Forest/ Mixed: 100,311 Upper Klamath Lake Subbasin Agricultural Land Use/ Cover Irrigated Crop/ Alfalfa: 3,396 27 Resource Concerns Water quality in the Upper Klamath Lake is a major resource concern, affecting subbasin fish survival, with phosphorus loading as the greatest factor. The loss of wetland vegetation around the lake has also been linked to lower survival rates for endangered suckers. The lower reaches of the Wood River and Sevenmile Creek provide some rearing habitat for larval and juvenile suckers. The Wood River, Sevenmile Creek and their tributaries support populations of bull and interior redband trout. A highly valued “ catch and release” sport fishery occurs on the Wood River and several of its tributaries. There is significant interest in enhancing riparian habitat along these streams to protect and promote these fisheries. Conservation Accomplishments In the Upper Klamath Lake Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved 12 acres of grazing lands and improved water quality and quantity on 12 acres of irrigated land. Several thousand more acres of wetland restoration are in the process of being planned or implemented around Upper Klamath Lake.

This can be accomplished by either converting pastures to permanent wildlife habitat or by creating riparian pastures. While most pastures are being inefficiently irrigated, conditions do not warrant extensive changes from current flood irrigation systems since water is reused or enters the soil profile Water Storage: In the Upper Klamath Lake Subbasin, the potential for non- traditional water storage presents a unique conservation opportunity. Restoring drained wetlands, still farmed around Upper Klamath Lake, could produce positive benefits for all four resource concerns. By actively managing areas for both seasonal wetlands and farming, water can be both filtered to improve water quality and stored in wetland areas for future use.

The valley once supported a vast network of wet meadows and marshes. This subbasin covers approximately 1.2 million acres and is split from the Middle Lost River Subbasin near Olene. Irrigated agriculture generally occurs in the warmer valleys. Flood is the most common pasture irrigation method, with about 50 percent of the water coming from the USBR project. Pasture condition is fair, and most pastures have not been renovated or re- leveled for some time. Maintenance would increase the efficiencies of 60 to 80 percent of the systems. Alfalfa is customarily sprinkler- irrigated and well- managed. Although irrigation efficiencies are higher than for pasture, many sprinkler systems still need upgrading. Several irrigated crops are grown in the subbasin including cereal grains, potatoes, and strawberry plants. Forestland, range and pasture are grazed by livestock. Rangelands are comprised of juniper and sagebrush steppes. Forestlands are generally mixed conifer. Livestock operations include cow/ calf, stockers and dairies. Confined livestock operations are located throughout the subbasin. The location and duration of confinement may pose a potential risk to water quality. Seven dairies located within the subbasin have existing liquid and dry livestock waste storage facilities.

High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving over the last 10 to 20 years. While agriculture is the dominant land use in this subbasin, other sources of phosphorus and other pollutants exist. Sewage treatment outfalls, on- site sewage disposal systems, wildlife, and natural inputs also contribute nutrients and other pollutants to the system. While historically the river had significant fish runs, it currently supports only a small population of Shortnose and Lost River suckers. Conservation Accomplishments In the Upper Lost River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved resource conditions on 234 acres of croplands and 5,282 acres of grazing lands, and have improved their management of irrigation water on 5,596 acres of irrigated lands. In addition, 846 acres of riparian and wetland areas have been restored.

On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops. Implementing practices like diverting clean water before it flows through livestock confinement areas near water sources, will reduce the risk of polluted runoff. Water Demand: On both surface-irrigated pastures and cropland areas, there are opportunities for land leveling or smoothing, lining or piping irrigation delivery ditches, upgrading irrigation systems and developing tailwater recovery systems to improve water use efficiency.

Farms near Klamath Falls tend to be smaller, indicating part- time or hobby operations. The area includes 12 irrigation districts and leased lands on the Lower Klamath Wildlife Refuge that receive water supplied by the USBR Klamath Project. Public lands include the refuge, and parts of Modoc and Klamath national forests. Irrigated agriculture includes pasture, alfalfa, cereal grain, potatoes, onions and mint. Roughly 70 percent is irrigated with USBR- supplied water; the rest is obtained from groundwater, individual surface water rights or special USBR contracts. Many fields are either flood or sprinkler irrigated depending on the year and crop. Most farm irrigation diversions lack a means to measure water delivery. Livestock operations include several dairies and cattle feeding operations. Substantial range acreage is used for livestock grazing. Pasture condition is fair and most pastures have not been renovated or re- leveled for some time. Pastures associated with smaller livestock operations in and around Klamath Falls appear to be in the most need of improved pastures and irrigation systems. Wildlife habitat: Ten river miles are in relatively good riparian condition given the river is used for conveying irrigation water. Some 13 miles of stream lack adequate riparian vegetation and streambank protection.

Drought conditions and increased competition for available water have increased economic, social, political and environmental concerns and uncertainty over the future. Habitat and water quality are two additional major resource concerns in the subbasin. High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other pollutant sources exist. While the river had significant historic fish runs, it currently supports only a small sucker population. Conservation Accomplishments In the last two years, the Middle Lost River Subbasin has seen significant conservation progress. With assistance from NRCS and local conservation districts, land managers have improved the condition of natural resources on 489 acres of cropland and 3,521 grazing land acres. In addition, 564 acres of riparian and wetland areas have been restored, and water use efficiency has been increased on 3,731 acres of irrigated lands.

Highly effective conservation measures on hay and cropland should focus on updating existing irrigation systems and improving irrigation water management. Water Quality: The use of grazing systems that rotate livestock through smaller pastures will increase forage production, reduce soil compaction and improve water quality. While fishery benefits from restoring riparian areas are minimal, streamside buffers will improve water quality and provide habitat for other wildlife. On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops.

The Tulelake Irrigation District and the Tulelake National Wildlife Refuge receive water from the USBR Klamath Project. Tulelake is a remnant of historic Lake Modoc that once connected the subbasin with both Lower and Upper Klamath Lake. The Lost River watershed was once a closed basin. Runoff flowed into Tulelake and evaporated. Pumping plants and drains constructed as a part of the project have provided an outlet from Tulelake, which now functions as an open basin. Irrigated agriculture is generally supplied by the USBR. Alfalfa, grain, potatoes, onions, mint and pasture are the principal crops. Fields are flood or sprinkler irrigated depending on the year and crop. Often diversions lack devices to measure water delivery. Pasture condition is fair, and most have not been renovated for some time. Groundwater provides 40- 50 percent of water for irrigated pastures, and most excess water is reused. Rangeland is the other significant land use. Most ranches are cow/ calf operations that have winter holdings in the subbasin. Rangelands are generally encroached with juniper. Wildlife habitat along the Lost River has reeds and bullrush, providing some habitat for waterfowl and songbirds. Suckers have been located in the river and Tulelake; however, it is not known whether they are successfully reproducing. There are few opportunities to improve habitat along this heavily manipulated reach of the river.

Irrigators depend on water- use decisions made by fellow irrigators and resource managers for their irrigation needs. Drought and increased competition for water leads to the primary resource concern in the basin - a reliable supply of water to meet agriculture, wildlife and other resource needs. Water quality deteriorates as it moves through the USBR project. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other sources of phosphorus and other pollutants exist. The presence of ESA- listed suckers creates concerns for improving habitat and water quality. The two national wildlife refuges support large waterfowl populations. Farmland on the refuges is leased to farmers to supply grain for waterfowl and shorebirds. These populations depend on refuges, leased lands and adjacent farms during the fall and spring migratory periods. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Tulelake Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, local land managers have improved the condition of natural resources on 72 cropland acres and 1,854 irrigated land acres, and have restored 21 acres of riparian and wetland areas.

Subsurface drainage could be added before re- establishing alfalfa stands, permitting better control of water table and soil moisture levels. During years that alfalfa fields are rotated to grain, winter flooding or pre- season irrigation could be used to reduce water demand. Water Storage/ Yield: Adding subsurface drainage may be the most significant practice to implement on cropland acres. Subsurface drains would allow farmers to winter flood or pre-irrigate fields, thereby reducing their demand for water during the irrigation season. If pre- irrigated, farmers could grow a cereal crop even if water deliveries are cut off during drought years. In addition, juniper control on rangelands will yield additional water to meet downstream needs.

While part of the Upper Klamath Basin, it is an internal drainage basin with only an artificial outlet. Groundwater flows from west to east out of the subbasin under the Mahogany Mountains toward the lake. A channel and pump plant were built to remove floodwaters. This channel is used infrequently and for only short durations. The Klamath National Forest, Butte Valley National Grassland, and the Butte Valley Wildlife Area make up the majority of the public lands. Irrigated agriculture includes alfalfa hay as the predominate crop. Cereal grains, potatoes and strawberry plants are also grown. Crops are usually sprinkler irrigated, and sprinklers are well maintained. Few irrigators measure water applied or schedule irrigation. Cattle operations graze irrigated pastures and meadows scattered throughout the subbasin along with range and forestlands. Pastures are generally flood irrigated and are supplied by streams. Most farm irrigation diversions lack water measuring devices. Mixed conifer forests are found at higher elevations and are generally operated as industrial forests. Range sites are dominated by Western Juniper and are generally in poor condition. Wildlife habitat is generally wetlands in the state wildlife refuge or on national grasslands. Approximately 26 miles of streams on private lands have inadequate riparian vegetation.

Generally, streams in the upper portions of the subbasin support good populations of Brown and Rainbow trout. The Tulelake National Wildlife Refuge and Lower Klamath Lake National Wildlife Refuge support large populations of migratory and permanent waterfowl. Farmland on the refuges is leased to area farmers to supply grain for the waterfowl and shorebirds. The large bird populations depend on the refuges, leased lands and adjacent farms throughout the fall and spring migratory periods for habitat. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds.

Other than limited contributions to groundwater in the Upper Klamath Basin, reductions in water demand only benefit the subbasin. Sprinkler- irrigated hay, cereal crops and row crops dominate land use on the better soils. Highly effective conservation on hay and cropland should focus on improving the overall irrigation efficiency of existing systems. This can be accomplished by upgrading systems and scheduling irrigation. An estimated 40 percent of the existing systems would benefit from maintenance. On controlled flood irrigated pastures, there are opportunities for land leveling or smoothing, lining or piping delivery ditches, and recovering tailwater. Additional water savings and water quality benefits could be gained by converting existing surface irrigation to sprinklers if power is available and affordable. On rangelands, juniper control and improved grazing management are the primary conservation opportunities.

Nearly half of the area is in public ownership. Iron Gate and Copco reservoirs are used extensively for recreational fishing, boating and camping. Whitewater rafting and kayaking are popular below the KC Boyle Dam. The KC Boyle, Copco and Iron Gate dams are used and regulated for power generation. Irrigated agriculture occurs on only 4,000 acres of pasture. Only a few isolated ranches are located in this subbasin. Cattle operations rotate grazing of irrigated pastures with significant acreage of grazed range and forest. Pastures are surface irrigated with a mix of controlled and flood irrigation. All irrigation water is diverted from the river or tributary streams. Most farm irrigation diversions lack devices to measure water. Even though overall irrigation application efficiency is low, the proximity of irrigated pastures to the river allows most excess water diverted to be reused downstream. Private forest and rangelands make up most of the private land, nearly all of which is used for livestock grazing. Much of the rangeland is in poor condition, with heavy juniper encroachment. More than half of the forest stands are overstocked with trees. Wildlife habitat along riparian areas is generally in good condition. Of the 12 miles of riparian areas surveyed, five would benefit from some restoration.

EXECUTIVE SUMMARY Limited historical references indicate that bull trout Salvelinus confluentus in Oregon were once widely spread throughout at least 12 basins in the Klamath River and Columbia River systems. No bull trout have been observed in Oregon's coastal systems. A total of 69 bull trout populations in 12 basins are currently identified in Oregon. A comparison of the 1991 bull trout status (Ratliff and Ho well 1992) to the revised 1996 status found that 7 populations were newly discovered and 1 population showed a positive or upgraded status while 22 populations showed a negative or downgraded status. The general downgrading of 32% of Oregon's bull trout populations appears largely due to increased survey efforts and increased survey accuracy rather than reduced numbers or distribution. However, three populations in the upper Klamath Basin, two in the Walla Walla Basin, and one in the Willamette Basin showed decreases in estimated population abundance or distribution. Some Oregon river basins have bull trout populations at extreme risk of extinction. This statewide status review listed only 19% of the bull trout populations in Oregon with a ulow risk of extinction" or "of special concern." Therefore, 81% of Oregon's bull trout populations are considered to be at a "moderate risk of extinction," "high risk of extinction," or "probably extinct." Populations in the Hood, Klamath, and Powder basins, as well as the Odell Lake population in the Deschutes basin, which contain only a few remaining bull trout, are examples of populations having a "moderate" or "high risk" of extinction. Approximately 55% of current bull trout distribution occurs on lands managed by the U.S. Forest Service. A much smaller proportion occurs on Bureau of Land Management managed lands (2%). Only 16% of current bull trout distribution occurs within a protected area defined as Wilderness, Wild and Scenic River, or within a National Park. The Northwest Forest Plan, Inland Native Fish Strategy, and Interim Strategies for Managing Anadromous Fish-producing Watersheds in Eastern Oregon and Washington, Idaho, and Portions of California have provided increased protection for bull trout habitat depending on their scope and geographic areas affected, and the extent to which they are being effectively implemented in watersheds containing bull trout. Recent reduction in timber production on National Forests (up to 50% in western Oregon National Forests and over 30% in eastern Oregon National Forests) should help improve riparian and stream habitat conditions for bull trout. The remaining bull trout distribution occurs on private, state, or tribal owned lands. A comparison of approximately 39 locations throughout the state with protective angling regulations on bull trout (in some areas more than one bull trout population is protected by one regulation) shows that all state managed areas were upgraded in a protective angling status or at least maintained in 1996 compared to 1989. Restrictive angling regulations prohibit angler harvest of all bull trout populations in Oregon except for one in the Deschutes Basin. Restrictive bull trout angling regulation changes (including the elimination of bull Vll trout harvest in all spawning areas) may be the major reasons why the Metolius River/Lake Billy Chinook and mainstem McKenzie River populations have shown significant increases in abundance. Statewide stocking of non-native brook trout, including the high lakes stocking program, has been discontinued in locations where managers believe brook trout could migrate downstream and potentially interact with native bull trout. Hatchery stocking of legal rainbow trout to promote recreational fisheries has been discontinued in most locations near bull trout populations to avoid incidental catch of bull trout. The spatial and temporal distributions of bull trout reported for each river basin in this status report should be used as an accurate baseline for fisheries managers. Current distribution and relative change of distribution should be useful indicators of population health and status. The GIS maps in this report provide a template to add new layers of data such as critical spawning and juvenile rearing areas, or as a method to compare distribution changes through time. Length frequency data are presented for most Oregon bull trout populations. This should provide estimates for the presence of multiple age classes and the percent of fluvial size life history component. Vlll

We analyzed the reproductive biology and demographics of the Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris, two endangered species endemic to the upper Klamath Basin of Oregon and California, from 1984-1997. Lost River suckers had distinct river and lake shoreline spawning stocks, and individuals of both species commonly spawned in consecutive years. In the Williamson River and lower Sprague River, spawning migration by both species occurred mainly during a 5-week period that started within the first three weeks of April and peaked between mid April and early May, although a separate, earlier (mid March) run of Lost River suckers may also spawn in the upper Sprague River. Migration of both species was several times higher at dawn (0500-0730 h) and evening (1800-2200 h) than other times of the day. Peak migrations almost always corresponded to peaks in water temperature, usually at 10-15°C. Lost River suckers were captured at springs along the east shore of the lake from late February through mid May, with peak spawning usually in mid March to mid April. Shortnose suckers were generally captured at the springs from late March through late May, but the time of peak spawning was not determined. Size and age at maturity was determined by recruitment from a strong year class (1991). Male Lost River suckers began recruitment into the adult population at age 4+ (375-475 mm). Substantial recruitment of females did not begin until age 7+ (510-560 mm). Male and female shortnose suckers began recruitment at age 4+, with the majority offish recruited by age 5+. Males recruited at 270-370 mm; females recruited at 325-425 mm. Fecundity estimates were quite variable ranging from 44,000-236,000 eggs per female Lost River sucker and 18,000-72,000 eggs per female shortnose sucker. In 1984 and 1985, the spawning populations of both species were dominated by large, old individuals, with little indication of recent adult recruitment. In the next 13 years, only one strong year class (1991) recruited into the spawning populations of both species. This year class temporarily boosted population numbers, but annual fish kills from 1995 to 1997 eliminated most adults of both species. Associated with poor water quality caused by the proliferation and decay of blue-green algae Aphanizomenonflos-aquae, these fish kills raise concern that alterations to the lake ecosystem over the past several decades have Perkins et al. Lost River and shortnose suckers 5 increased the magnitude and frequency of poor water quality. As a result, mortality rates of all life stages may have increased, thereby disrupting the species' life history pattern and potentially decreasing long-term population viability. Introduction The Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris are large, long-lived suckers endemic to the upper Klamath Basin of Oregon and California. Both species are typically lake dwelling but migrate to tributaries or shoreline springs to spawn (Moyle 1976, Scoppettone and Vinyard 1991). Once extremely abundant (Cope 1884, Gilbert 1898), both species have experienced severe population declines and were federally listed as endangered in 1988 (USFWS 1988). Much of the original habitat of these suckers has been destroyed or altered by conversion of lake areas to agriculture, dams, instream flow diversions, and water quality problems associated with timber harvest, loss of riparian vegetation, livestock grazing, and agricultural practices (USFWS 1988). Knowledge of the life history of Lost River and shortnose suckers is fundamental to recovery of these species. The objective of this report was to present the results of studies conducted from 1987-1998 on the reproductive biology and demographics of Lost River and shortnose suckers, and to compare these results with earlier unpublished data. Study Sites Studies were conducted on Upper Klamath Lake and the lower Williamson-Sprague river system (Figure 1). These waters form the upper portion of the Klamath River Basin in south-central Oregon and represent most remaining native habitat of Lost River and shortnose suckers. Upper Klamath Lake is a remnant of pluvial Lake Modoc that included eight major basins and encompassed 2,839 km2 (Dicken 1980). Today, Upper Klamath Lake serves as a storage reservoir that provides water for agricultural irrigation, waterfowl refuges, instream flow requirements of anadromous fish, and hydroelectric power generation. At full capacity, the lake covers approximately 360 km2 and has an average depth of 2.4 m. Most deeper water (3-12 m) is restricted to narrow trenches along the western shore. Lake elevation is controlled at the outlet by Link River

Abstract "Seeking Refuge" examines the history of migratory waterfowl management along the Pacific Flyway, the westernmost of four main migration routes in North America. Drawing on approaches from historical geography and environmental history, this study shows how wildlife officials developed migratory bird refuges in Oregon and California, where over 60 percent of Pacific Flyway waterfowl winter. During the early-twentieth century, reclamation and river diking eliminated most of the wetlands in the birds' wintering range. Bird enthusiasts such as bird watchers and duck hunters successfully lobbied for the creation of wildlife refuges in a few areas along the flyway. These early refuges failed to protect waterfowl habitat and they were severely degraded by reclamation. In the 1930s and 1940s, the U.S. Fish and Wildlife Service (FWS) and its predecessor, the Bureau of Biological Survey, undertook an ambitious program to resurrect these sanctuaries and to create new ones. Many farmers opposed these refuges out of fear that waterfowl would damage crops. To respond to these concerns and to ensure an adequate food supply for the birds, the FWS raised rice, barley, and other grains. The agency adopted many of the technologies of modern, industrial agriculture including synthetic herbicides and insecticides such as 2, 4-D and DDT. By the 1960s, the refuges had become largely mirrors of the surrounding irrigated farmlands, the main difference being that the FWS raised grain for waterfowl rather than for market. Refuges could not escape the agricultural settings in which they were embedded. As units within the irrigated countryside, Pacific Flyway refuges were often at the mercy of nearby farmers and federal reclamation agencies. Poor water quality and insufficient supplies of water often hampered FWS efforts to manage refuges. In the late-twentieth century, reduced water supply due to diversions to California municipalities and to sustain endangered fish species affected the amount of water reaching refuges. This dissertation has other goals. First, it critiques the anthropocentrism of most historical geography by focusing on how political, cultural, and ecological factors affected wildlife. Second, it contributes to the literature on the state's role in environmental protection by investigating the overlapping, and often contradictory, spaces within which wildlife managers implemented environmental regulations.
