Major issues in recent years have included changing the role of science in decision-making, modifying critical habitat procedures, reducing conflicts with Department of Defense activities, incorporating further protection and incentives for property owners, and increasing protection of listed species, among others. In addition, many have advocated enacting as law some ESA regulations promulgated during the Clinton Administration. The ESA has been one of the more contentious environmental laws. This may stem from its strict substantive provisions, which can affect the use of both federal and non-federal lands and resources. Under the ESA, species of plants and animals (both vertebrate and invertebrate) can be listed as endangered or threatened according to assessments of their risk of extinction. Once a species is listed, powerful legal tools are available to aid its recovery and protect its habitat. The ESA may also be controversial because dwindling species are usually harbingers of broader ecosystem decline: the most common cause of listing species is habitat loss. The authorization for spending under the ESA expired on October 1, 1992. The prohibitions and requirements of the ESA remain in force, even in the absence of an authorization, and funds have been appropriated to implement the administrative provisions of the ESA in each subsequent fiscal year. In the 108th Congress, two bills were reported by the House Committee on Resources, but not enacted, that would have amended the ESA to modify scientific peer review and critical habitat procedures. Interior appropriations measures funded Fish and Wildlife Service programs related to endangered species (P.L. 108-108 provided $265 million for FY2004; P.L. 108-447 provided $262 million for FY2005). P.L. 108-136 (Defense authorization) included an ESA amendment to direct that critical habitat not be designated on military lands under certain conditions when Integrated Natural Resources Management Plans are in effect. P.L. 108-137 (Energy and Water appropriations) prohibited use of FY2004 or earlier funds to reduce water deliveries under existing contracts for ESA compliance for the silvery minnow on the Middle Rio Grande River unless water is obtained from a willing seller or lessor; this prohibition appears to have been made permanent by ?205 of Div. C of P.L. 108-447. P.L. 108-148 (Healthy Forests Act) authorized hazardous fuels reduction projects on BLM and national forest lands, including those containing habitat for listed species; directed establishment of a healthy forests reserve program to promote recovery of listed species; and directed the Secretary of the Interior to provide property rights assurances to landowners enrolled in the healthy forests reserve program.

The problem is a natural one; it has not been caused by man's carelessness and cannot be turned around by regulation. Upper Klamath Lake is quite shallow, warming rapidly in the summer, and the waters carry a naturally occurring high nutrient load. Algal growth is extensive, predominently APHANEZOMENON FLOS-AQUAE, a blue-green algae prevalent in eutrophic waters. These organisms form dense mats that become very odorous as they decay. Numerous macrophytes (aquatic weeds) are indigenous to the lake, but the major problem is with P0TAM06ET0N CRISPUS, which forms long floating fonds that tangle boat motors and prevent passage. The Pelican Bay channel has an extensive growth of this weed.

Lindenberg, and Tamara Abstract During June-October 2005, water quality data were collected from Upper Klamath and Agency Lakes In Oregon, and meteorological data were collected around and within Upper Klamath Lake. Data recorded at two continuous water quality monitors In Agency Lake showed similar temperature patterns throughout the field season, but data recorded at the northern site showed more day-to-day variability for dissolved oxygen concentration and saturation after late June and more day-to-day variability for pH and specific conductance values after mid-July. Data recorded from the northern and southern parts of Agency Lake showed more comparable day-to-day variability in dissolved oxygen concentrations and pH from September through the end of the monitoring period. For Upper Klamath Lake, seasonal (late July through early August) lows of dissolved oxygen concentrations and saturation were coincident with a seasonal low of pH values and seasonal highs of ammonia and orthophosphate concentrations, specific conductance values, and water temperatures. Patterns in these parameters, excluding water temperature, were associated with bloom dynamics of the cyanobacterium (blue-green alga) Aphanizomenonflos-aquae in Upper Klamath Lake. In Upper Klamath Lake, water temperature in excess of 28 degrees Celsius (a high stress threshold for Upper Klamath Lake suckers) was recorded only once at one site during the field season. Large areas of Upper Klamath Lake had periods of dissolved oxygen concentration of less than 4 milligrams per liter and pH value greater than 9.7, but these conditions were not persistent throughout days at most sites. Dissolved oxygen concentrations in Upper Klamath Lake on time scales of days and months appeared to be influenced, in part, by bathymetry and prevailing current flow patterns. Diel patterns of water column stratification were evident, even at the deepest sites. This diel pattern of stratification was attributable to diel wind speed patterns and the shallow nature of most of Upper Klamath Lake. Timing of the daily extreme values of dissolved oxygen concentration, pH, and water temperature was less distinct with increased water column depth. Chlorophyll a concentrations varied spatially and temporally throughout Upper Klamath Lake. Location greatly affected algal concentrations, in turn affecting nutrient and dissolved oxygen concentrations—some of the highest chlorophyll a concentrations were associated with the lowest dissolved oxygen concentrations and the highest un-ionized ammonia concentrations. The occurrence of the low dissolved oxygen and high un-ionized ammonia concentrations coincided with a decline in algae resulting from cell death, as rn.easu.red by concentrations of chlorophyll a. Dissolved oxygen production, rates in. experim.en.ts were as high as 1.47 milligrams of oxygen per liter per hour, and consumption rates were as much as -0.73 milligrams of oxygen per liter per hour. Dissolved oxygen, consumption rates measured in. this study were comparable to those measured in a 2002 Upper Klamath Lake study, and a higher rate of dissolved oxygen consumption was recorded in. dark bottles positioned higher in the water column. Data, though, inconclusive, indicated that a decreasing trend of dissolved oxygen productivity through July could have contributed to the decreasing dissolved oxygen concentrations and percent saturation recorded in Upper Klamath Lake during this time. Phytoplankton self-shading was evident from, a general inverse relation between depth of photic zone and chlorophyll a concentrations. This shading caused net dissolved oxygen consumption during daylight hours in lower parts of the water column that would otherwise have been in the photic zone. Meteorological data collected in and around Upper Klamath Lake showed that winds were likely to come from a broad range of westerly directions in the northern one-third of the lake, but tended to come from a narrow range of northwesterly directions over the main body of the lake farther south.

  	Citation × Citation Citation Abstract Copy Title: Status of Oregon's bull trout : distribution, life history, limiting factors, management considerations, and status Author: Buchanan, David V; Hanson, Mary L; Hooton, Robert M Year: 1997, 2007, 2005 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.
