The extent of the area irrigated, or that may be irrigated by reason of Bureau of Reclamation activities, is approxi-mately 140,000 acres. This includes about 20,000 acres suitable only for pasture and approximately 12,000 acres of good land in the Tule Lake division not yet opened for settlement. Within the older developed sections of the project the soil is mostly of a sandy loam . type that is particularly suitable for growing potatoes and summer vegetables as well as all of the ordinary crops that thrive in a cool, tem-perate climate. The price of this type of land ranges from $ 100 to $ 200 per acre. The water- right cost, which origi- Klamath Falls, Oregon, the prolect office headquarters nally was about $ 55 per acre, is approximately half paid up. The balance has an average of about 25 years to run without interest. Operation and maintenance costs usually run about $ 1.25 an acre per annum. I R R I G A B L E L A N D S The Tule Lake division of the project, which will eventually comprise about 32,000 acres of agricultural land and about 5,000 acres of thin soil land good only for pasture, carries a construction charge of $ 88.35, with 40 years in A! Klamath : desert. Looking~ southwest up Lan Valley from a point 4 miles west of Lorella, Ore which to pay without interest. No payments have been required to date, but the Secretary of the Interior will soon issue public notice announcing the commencement of pay-ments, which will be approximately $ 2.20 per acre each year. In addition to the construction charge, there is an operation and maintenance charge which will probably run between $ 1.50 and $ 2 un acre a year. These lands are of lacustrian origin and are very fertile. They are particularly adapted to the growth of small grains, alfalfa, and pasture grasses. Patented land in this division sells for $ 50 to $ 100 per acre. Patented lands in private ownership, where of goc; d quality, well improved and conveniently situated, can be purchased for from $ 150 to $ 200 per acre. Good lands not so well improved nor so desirably located sell at around $ 100 per acre. There is very little undeveloped, privately owned good land on the project. Small tracts of 5, 10, or 20 acres, located along paved highways and within 6 to 8 miles of Klamath Falls, are obtainable at from $ 200 to $ 400 per acre. W A T E R S U P P L Y The Klamath project is ! ortunate in having an abundant water supply for all lands susceptible of irrigation. The map on the inside of the back cover page shows the location of the three reservoirs and their immediate proximity to the lands they serve. The irrigable project lands lie between elevations of 4,035 and 4,070 feet above sea level and occupy the Klamath Basin and the Valley of Lost River, situated in south central Oregon and north central California, about 150 miles east of the Pacific coast. The average annual pre-cipitation is 12.51 inches. SCHOOLS Klamath County schools are run on the county unit basis Public School in Klamath Falls and are fully up to standard. Busses run at county expense transport rural children to and from school, and there is no lost time on account of bad weather. Within the county there are 9,242 children of school age, 4,107 of these within the city of Klamath Falls. The high school enrollment for Klamath Falls is 1,156, and for the remainder of the county is 459. There are 9 high schools in the county that employ 62 teachers. The grade schools employ 185 teachers, of whom' 76 are in the city of Klamath Falls. : let of concrete flume, Canal C, of the main project structures R E C R E A T I O N No part of the United States affords more interesting and attractive recreational areas than are found near at hand and in all directions from the Klamath project. From 1 to 2 hours in any kind of an automobile is sufficient to land one on the banks of a cold mountain stream inhabited by many wary trout or alongside the shores of any one of a half dozen crystal lakes, where boating and bathing may be enjoyed to the full. Some of the lakes that are conven-iently located with reference to the project, and where many summer camps as well as extensive hotel and camp accommodations already exist, are Upper Klamath Lake, Lake of the Woods, Crater Lake, Diamond Lake, Crescent I., ake, Ode11 Lake, and Paulina Lake. The most distant of the lot, Paulina Lake, can be reached in 3 hours' driving from Klamath Falls. Some of the important recreational areas lying in convenient distances from the project are shown in the ilh~ strationsa ccompanying this chapter. The principal water supply is in Upper Klamath Lake, where regulation provides a possible storage of about 524,800 acre- feet, and this with the natural inflow insures the lands served from this source an adequate water supply at all times. Under the terms of the contract dated February 24, 1917, between the United States and the California- Oregon Power Co., the power company was given the right to regulate the outflow of Upper Klamath Lake, subject to existing rights and the prior rights of the Klamath project for water for irrigation. To regulate the outflow, the company, in 1921, constructed the Link River Dam at a cost of about $ 310,000. Storage for the lands on the west side of Langell Valley and a portion of the lands in the Horsefly irrigation district is provided by Clear Lake Reservoir. This reservoir, lying just across the line in California, is the source of Lost River and has a total capacity of 454,000 acre- feet, most of which was made available during 1931 by the construction of a channel from the outlet works to the deeper portion of the reservoir, a distance of about 6 miles. The reservoir is also used for flood storage for the protection of lands in the Tule Lake division. Gerber Reservoir, on Miller Creek, a tributary of Lost River, has a storage capacity of 94,000 acre- feet and fur-nishes a water supply for the lands on the east side of Lost River in the Langell Valley division. This reservoir also provides for the storage of flood water for the protection of lands in the Tule Lake division. Water from Upper Klamath Lake is diverted to the main or " A" canal from the east side of Link River, the outlet of the lake, several hundred feet below the lake and a few I I / Klamath River near Klamath Falls k River diversion dam Alfalfa field near Malin, Oreg. Two cuttings are grown, which yield 2- 4 tons per acre on the older project lands, and 3- 6 in Tule Lake section hundred feet above Link River Dam. Water for all lands in the main and pumping divisions and for a portion of the lands in the Tule Lake division are diverted through the " A" canal. Additional water for the lands in the Tule Lake division is diverted from the Klamath River, through the Lost River diversion channel ( reversing the direction of flow), and spilled into Lost River, frcm which it is diverted to the " J" canal at a point about 3 miles southeasterly from Merrill, Oreg. At this point the river level is raised about 12 feet by means of the lower Lost River diversion dam, a concrete structure of the Ambursen type, with a crest length of 204 feet. The Lost River diversion channel leads off from Lost River at a point about 10 miles southeast of Klamath Falls, Oreg., immediately above a hollow U- shaped concrete dam which raises the river level about 23 feet. Prior to the Irrigating a 65- acre field of potatoes; showing application of m irrigation season the flow of Lost River is diverted to the Klamath River and wasted; however, after the spring flood flow of Lost River has passed and water for irrigation in the Tule Lake division is required, the flow of Lost River is ~ assed through the dam and down to the " J" canal. This flow is augmented, when demand is heavy, from Klamath River as indicated ahve. Lands on the east side of Langell Valley division are served by the north canal, which diverts water from Miller Creek at the Miller Creek Dam, located about 6 miles below Gerber Dam. At this point the water surface in Miller Creek is raised by placing flashboards against wooden trestles, the grade of the canal and that of the stream being substan-tially the same elevation. The lands on the west side of Lost River in the Langell Valley division are served by the West Canal, which diverts water from Lost River at the Malone Dam, located about 42 miles southeasterly from Klamath Falls, Oreg. At this point the level of Lost River is raised about 18 feet by means of an earth diversion dam. Clear Lake Reservoir provides storage for the West Canal. TOWNS Klamath Falls, Merrill, Malin, and Bonanza are project towns, the first named being the principal city in southern, Oregon east of the Cascades. It has a population of approximately 16,000 and is the distributing center for a large territory. Klamath County has a population of 32,400, one- half residing in the city of Klamath Falls and perhaps 4,000 more in suburban districts only a few miles away. Merrill and Malin are small towns within the irrigated area with populations of six or seven hundred each. In Klamath Basin are some 1,800 farms and approximately as many farm families. LUMBERING Approximately 30 mills and box factories are in operation, this district being the largest manufacturing center of box shook in the United States. The Klamath district contains the heaviest stand of yellow pine left in the United States. Throughout the spring, summer, and fall all lumber com-panies maintain large pay rolls both in the plants and in the lumber camps. Lumber contributes greatly to the heavy traffic originating at K! amath Falls, making this city the second largest shipping point in Oregon. The majority of the mills and box factories are located in or near Klamath Falls. T R A N S P O R T A T I O N Two main- line railways, the Southern Pacific and Great Northern, enter Klamath Falls and traverse the project throughout its longest dimension. Hard- surfaced highways radiate from Klamath Falls in all directions, connecting with Portland, Sun Francisco, and Salt Lake. These high-ways supplemented by county market roads penetrate all sections of the project, with the result that few farms are more than a mile from a hard- surfaced outlet. CLIMATE The Klamath Basin has a remarkably pleasant and healthful climate. Winters are not cold, and summers are not hot. Precipitation, which amounts to about 12): inches a year on the average, falls mainly from November to April. Late and early frosts are to be expected, and occasionally light frosts occur even in the summer months. me on the Main division of the project A G R I C U L T U R E The principal crops grown are potatoes, alfalfa, small grains, and vegetables. The yield of small grains in the Tule Lake area is unusually high. Oats frequently make 100 bushels per acre; barley runs from 60 to 80; and any good wheat field will thresh out more than 40 bushels per acre. Potatoes, when conditions are right, are par excelience the big money crop. A good yield of tubers is considered to be around 150 sacks of U. S. No. 1' s per acre, and every year a few fields are reported with yields of double that amount. The price for potatoes is unstable, depending on the market demand, and ranges from about 50 cents to $ 1.50 a sack. The quality of Klamath potatoes on the Sun Francisco market is recognized as the best, and the price usually ranges from 10 to 20 cents a sack higher than is paid for Washington and Idaho production. Flock of 6,000 turkeys being fattened for market L I V E S T O C K Cattle. On account of its geographical location, sur-rounded as it is with immense areas of sagebrush plateaus and forest ranges, the Klamath project is, and probably always will be, essentially a stock country. Its cheap forage, abundant water and mild winters offer ideal con-ditions for the wintering of range stock and the fattening of mature animals for market. Favorable feeding- in- transit rates for both grass and feed lot cattle have resulted in the fattening, locally, of thousands of range and outside cattle. The beef industry alone returns approximately $ 900,000 annually. There are several killing and manu-facturing plants located in Klamath Falls. Sheep. Approxinately 150,000 ewes are maintained in the Klamafh Basin with an average annual output of about three- quarters of a million dollars.

There are now about 8,000 milk cows in the district. Klamath Falls, with its large industrial popu-lation, furnishes a good market for milk, butter, and cheese. Two local cooperative cheese manufacturing plants and four privately owned creameries operate in the district. The value of the dairy industry is approximately $ 600,000 annually. Local dairy prices for butterfat are maintained at l> e to 2 cents above the State average cwing to the favored position of the project-- half- way between Portland and Sun Francisco. This district offers many opportunities for increased dairying production, as costs are compara-tively low and climatic conditions are favorable.

  	Citation × Citation Citation Abstract Copy Title: Bull Trout, Salvelinus Confluentus... Draft Recovery Plan, Chapter 1, Introduction... Author: U.S. Fish and Wildlife Service Year: 2003, 2008, 2005 EXECUTIVE SUMMARY FOR THE BULL TROUT RECOVERY PLAN Current Species Status The bull trout (Salvelinus confluentus) in the coterminous United States was listed as threatened on November 1, 1999 (64 FR 58910). Earlier rulemakings had listed distinct population segments of bull trout as threatened in the Columbia River, Klamath River, and Jarbidge River basins (63 FR 31647, 63 FR 42757, 64 FR 17110). Bull trout distribution, abundance, and habitat quality have declined rangewide. Several local extirpations have been documented, beginning in the 1950fs. Bull trout continue to occur the Klamath River, Columbia River, Jarbidge River, St. Mary-Belly River, and Coastal-Puget Sound, in the states of Idaho, Montana, Nevada, Oregon, and Washington. Habitat Requirements and Limiting Factors Bull trout have more specific habitat requirements than most other salmonids. Habitat components that influence bull trout distribution and abundance include water temperature, cover, channel form and stability, substrate for spawning and rearing, and migratory corridors. Bull trout are found in colder streams and require colder water than most other salmonids for incubation, juvenile rearing, and spawning. Spawning and rearing areas are often associated with cold-water springs, groundwater infiltration, and/or the coldest streams in a watershed. Throughout their lives, bull trout require complex forms of cover, including large woody debris, undercut banks, boulders, and pools. Alterations in channel form and reductions in channel stability result in habitat degradation and reduced survival of bull trout eggs and juveniles. Channel alterations may reduce the abundance and quality of side channels, stream margins, and pools, which are areas bull trout frequently inhabit. For spawning and early rearing bull trout require loose, clean gravel relatively free of fine sediments. Because bull trout have a relatively long incubation and development period within spawning gravel (greater than 200 days), transport of bedload in unstable channels may kill young bull trout. Bull trout use migratory corridors to move from spawning and rearing habitats to foraging and overwintering habitats and back. Different habitats provide bull trout with diverse resources, and migratory corridors allow local populations to connect, which may increase the potential for gene flow and support or refounding of populations. Declines in bull trout distribution and abundance are the results of combined effects of the following: habitat degradation and fragmentation, the blockage of migratory corridors, poor water quality, angler harvest and poaching, entrainment (process by which aquatic organisms are pulled through a diversion structure or other device) into diversion channels and dams, and introduced iv normative species. Specific land and water management activities that continue to depress bull trout populations and degrade habitat include dams and other diversion structures, forest management practices, livestock grazing, agriculture, road construction and maintenance, mining, and urban and rural development. Some threats to bull trout are the continuing effects of past land management activities. Organization and Development of the Recovery Plan Because bull trout in the coterminous United States are widely distributed within a large area, the recovery plan is organized into multiple chapters. This introductory chapter (Chapter 1) describes our overall recovery strategy for the species, defines recovery, and identifies recovery actions applicable for all listed bull trout in the coterminous United States. Each successive chapter focuses on bull trout in specific geographic areas (recovery units), and describes conditions, defines recovery criteria, and identifies specific recovery actions for the recovery unit. Recovery Objectives The goal of this recovery plan is to describe the actions needed to achieve the recovery of bull trout, that is, to ensure the long-term persistence of self-sustaining, complex interacting groups (or multiple local populations that may have overlapping spawning and rearing areas) of bull trout distributed across the species' native range. Recovery of bull trout will require reducing threats to the long-term persistence of populations, maintaining multiple interconnected populations of bull trout across the diverse habitats of their native range, and preserving the diversity of bull trout life-history strategies (e.g., resident or migratory forms, emigration age, spawning frequency, local habitat adaptations). To recover bull trout, the following four objectives have been identified: ? Maintain current distribution of bull trout within core areas as described in recovery unit chapters and restore distribution where recommended in recovery unit chapters. ? Maintain stable or increasing trend in abundance of bull trout. ? Restore and maintain suitable habitat conditions for all bull trout life history stages and strategies. ?

Additional objectives may be necessary to achieve recovery in some recovery units and will be identified in the respective recovery unit chapters. Recovery Criteria Criteria are established to assess whether recovery objectives are being achieved. Criteria specific to each recovery unit are defined in each recovery unit chapter. Individual chapters may contain criteria for assessing the status of bull trout and alleviation of threats that are unique to one or several recovery units.

The distribution of bull trout in identified and potential local populations in all core areas within the recovery unit. ? The estimated abundance of adult bull trout within core areas in the recovery unit, expressed as either a point estimate or a range of individuals. ? The presence of stable or increasing trends for adult bull trout abundance in the recovery unit. ? The restoration of passage at specific barriers identified as inhibiting recovery.

Draft Recovery Plan, Chapter 1, Introduction... Author: U.S. Fish and Wildlife Service Year: 2003, 2008, 2005 EXECUTIVE SUMMARY FOR THE BULL TROUT RECOVERY PLAN Current Species Status The bull trout (Salvelinus confluentus) in the coterminous United States was listed as threatened on November 1, 1999 (64 FR 58910). Earlier rulemakings had listed distinct population segments of bull trout as threatened in the Columbia River, Klamath River, and Jarbidge River basins (63 FR 31647, 63 FR 42757, 64 FR 17110). Bull trout distribution, abundance, and habitat quality have declined rangewide. Several local extirpations have been documented, beginning in the 1950fs. Bull trout continue to occur the Klamath River, Columbia River, Jarbidge River, St. Mary-Belly River, and Coastal-Puget Sound, in the states of Idaho, Montana, Nevada, Oregon, and Washington. Habitat Requirements and Limiting Factors Bull trout have more specific habitat requirements than most other salmonids. Habitat components that influence bull trout distribution and abundance include water temperature, cover, channel form and stability, substrate for spawning and rearing, and migratory corridors. Bull trout are found in colder streams and require colder water than most other salmonids for incubation, juvenile rearing, and spawning. Spawning and rearing areas are often associated with cold-water springs, groundwater infiltration, and/or the coldest streams in a watershed. Throughout their lives, bull trout require complex forms of cover, including large woody debris, undercut banks, boulders, and pools. Alterations in channel form and reductions in channel stability result in habitat degradation and reduced survival of bull trout eggs and juveniles. Channel alterations may reduce the abundance and quality of side channels, stream margins, and pools, which are areas bull trout frequently inhabit. For spawning and early rearing bull trout require loose, clean gravel relatively free of fine sediments. Because bull trout have a relatively long incubation and development period within spawning gravel (greater than 200 days), transport of bedload in unstable channels may kill young bull trout. Bull trout use migratory corridors to move from spawning and rearing habitats to foraging and overwintering habitats and back. Different habitats provide bull trout with diverse resources, and migratory corridors allow local populations to connect, which may increase the potential for gene flow and support or refounding of populations. Declines in bull trout distribution and abundance are the results of combined effects of the following: habitat degradation and fragmentation, the blockage of migratory corridors, poor water quality, angler harvest and poaching, entrainment (process by which aquatic organisms are pulled through a diversion structure or other device) into diversion channels and dams, and introduced iv normative species. Specific land and water management activities that continue to depress bull trout populations and degrade habitat include dams and other diversion structures, forest management practices, livestock grazing, agriculture, road construction and maintenance, mining, and urban and rural development. Some threats to bull trout are the continuing effects of past land management activities. Organization and Development of the Recovery Plan Because bull trout in the coterminous United States are widely distributed within a large area, the recovery plan is organized into multiple chapters. This introductory chapter (Chapter 1) describes our overall recovery strategy for the species, defines recovery, and identifies recovery actions applicable for all listed bull trout in the coterminous United States. Each successive chapter focuses on bull trout in specific geographic areas (recovery units), and describes conditions, defines recovery criteria, and identifies specific recovery actions for the recovery unit. Recovery Objectives The goal of this recovery plan is to describe the actions needed to achieve the recovery of bull trout, that is, to ensure the long-term persistence of self-sustaining, complex interacting groups (or multiple local populations that may have overlapping spawning and rearing areas) of bull trout distributed across the species' native range. Recovery of bull trout will require reducing threats to the long-term persistence of populations, maintaining multiple interconnected populations of bull trout across the diverse habitats of their native range, and preserving the diversity of bull trout life-history strategies (e.g., resident or migratory forms, emigration age, spawning frequency, local habitat adaptations). To recover bull trout, the following four objectives have been identified: ? Maintain current distribution of bull trout within core areas as described in recovery unit chapters and restore distribution where recommended in recovery unit chapters. ? Maintain stable or increasing trend in abundance of bull trout. ? Restore and maintain suitable habitat conditions for all bull trout life history stages and strategies. ? Conserve genetic diversity and provide opportunity for genetic exchange. ? These objectives apply to bull trout in all recovery units. Additional objectives may be necessary to achieve recovery in some recovery units and will be identified in the respective recovery unit chapters. Recovery Criteria Criteria are established to assess whether recovery objectives are being achieved. Criteria specific to each recovery unit are defined in each recovery unit chapter. Individual chapters may contain criteria for assessing the status of bull trout and alleviation of threats that are unique to one or several recovery units. However, every recovery unit chapter will contain criteria that address the following characteristics: ? The distribution of bull trout in identified and potential local populations in all core areas within the recovery unit. ? The estimated abundance of adult bull trout within core areas in the recovery unit, expressed as either a point estimate or a range of individuals. ? The presence of stable or increasing trends for adult bull trout abundance in the recovery unit. ? The restoration of passage at specific barriers identified as inhibiting recovery. We expect recovery of bull trout to be a dynamic process occurring over time. The recovery objectives are based on our current knowledge and may be refined as more information becomes available. Some local populations of bull trout, and possibly core area populations, may be extirpated even though recovery actions are being implemented.

For example, it may be possible for the Columbia River Distinct Population Segment, which has 22 recovery units, to be recovered prior to all recovery unit criteria being met in all recovery units. Success in accomplishing the recovery VI criteria will be reviewed and considered for the impacts both within a recovery unit and throughout a distinct population segment.

  	Citation × Citation Citation Abstract Copy Title: Oregon lampreys : natural history, status, and analysis of management issues Author: Kostow, Kathryn Year: 2002, 2008, 2005 Executive Summary The jawless lampreys are remnants of the oldest vertebrates in the world. Oregon has somewhere between eight and a dozen species of these primitive fishes. Their taxonomy is obscure because different species tend to look very similar through most of their life cycle, and they have not been well-studied in Oregon. Lampreys occur in the Columbia Basin, including the lower Snake River, along the Oregon coast, in the upper Klamath Basin, and in Goose Lake Basin in southeastern Oregon. They all begin life in fresh water where juveniles burrow into silt and filter feed on algae. As some species approach adulthood they migrate to the ocean or to lakes where they briefly become ecto-parasites, feeding on other live fishes by attaching to them with sucker disc mouths. Other species remain non-parasitic. In addition to some enigmatic species identities, we generally have very little information about the detailed distributions, life histories and basic biology of lampreys. Lampreys became a conservation concern in the early 1990s when tribal co-managers and some Oregon Department of Fish and Wildlife (ODFW) staff noted that populations of Pacific Lampreys, Lampetra tridentata, were apparently declining to perilously low numbers. Pacific Lampreys were listed as an Oregon State sensitive species in 1993 and were given further legal protected status by the state in 1997 (OAR 635-044-0130). Lamprey status is difficult to assess for several reasons: 1) Most observations of lampreys in fresh water are of juveniles and it is difficult to tell the various species apart, even to the extent that the various species are currently clearly designated; 2) Data on lamprey is only collected incidental to monitoring of salmonids. The design and efficiency of the data collection effort is not always adequate for lampreys; and 3) We have very few historic data sets for lampreys. Therefore we often cannot determine how the abundances and distributions we see now compare with those in the past. The limited data that we have suggests that lampreys have declined through many parts of their ranges. The most precipitous declines appear to be in the upper Columbia and Snake basins where we have some historic data from mainstem dam counts. Pacific Lampreys have declined to only about 200 adults annually passing the Snake River dams. We also have evidence of declines of Pacific Lampreys in the lower Columbia and on the Oregon coast, although our data is quite limited. We have little to no information about any of the other species of lampreys. We are not even sure whether some of the recognized species, like the River Lamprey (L. ayresi), is still present in Oregon. This paper concludes with a Problem Analysis for Oregon lampreys. Our biggest problem is poor information, ranging from not knowing basic species identity to having inefficient or no systematic monitoring of lamprey abundance and distribution. ODFW continued an annual harvest on Pacific Lamprey in the Willamette Basin in 2001, but we lack the necessary information to assess the affects of the harvest on the population. Major habitat problems that affect lampreys include upstream passage over artificial barriers, a need for lamprey-friendly screening of water diversions, and urban and agricultural development of low-gradient flood plain habitats.
