The workshop was designed to review and discuss scientifically credible data and publications about 1) factors related to human activity that influence stream temperature and 2) behavioral, physical, and ecological mechanisms of cold water fish species for existing in streams with elevated temperatures. The goal of the workshop was to review empirical evidence and to identify points of agreement, disagreement, and knowledge gaps within the scientific community concerning the factors that influence stream temperature and fish responses to elevated temperatures. This information will assist the IMST in preparing a broader temperature report on Oregon's stream temperature water quality standards and their implementation. This report is prepared by the IMST. It was reviewed by workshop participants and revised by the IMST accordingly. The report includes abstracts of plenary presentations on factors that influence stream temperatures and fish responses, and the results of group discussions. The workshop participants focused on three main questions and were asked to list statements of agreement and disagreement, and to identify gaps in the scientific knowledge related to each question: ? How and where does riparian vegetation influence stream temperature? ? Do other changes in streams cause increases in stream temperature? ? How can apparently healthy fish populations exist in streams with temperatures higher than laboratory and field studies would indicate as healthy? The workshop participants provided answers to the questions in the form of bullets. The answers below represent the IMST's summation of the workshop findings and were reviewed by the participants. Several gaps in the scientific basis for specific questions or relationships were identified. The participants found no areas of disagreement for which technical information was available. They noted that any disagreements were not related to scientific interpretation, but were based on concerns or opinions about application, regulation, and management. How and where does riparian vegetation influence stream temperature? The influence of riparian vegetation on stream temperature is cumulative and complex, varying by site, over time, and across regions. Riparian vegetation can directly affect stream temperature by intercepting solar radiation and reducing stream heating. The influence of riparian shade in controlling temperature declines as streams widen in downstream reaches, but the role of riparian vegetation in providing water quality and fish habitat benefits continues to be important. Besides providing shade, riparian vegetation can also indirectly affect stream temperature by influencing microclimate, affecting channel morphology, affecting stream flow, influencing wind speed, affecting humidity, affecting soil temperature, using water, influencing air temperature, enhancing infiltration, and influencing thermal radiation. It is critical to know the site potential to understand what vegetation a site can support. There is not a good scientific understanding of how much vegetation shading is required to affect stream temperature. 1 This lack of understanding may be due to the spatial and temporal variability in landscape components, and the resulting variability in both the direct and indirect influences of vegetation on stream temperature. Therefore, it is difficult to generalize about the effects of vegetation on stream temperature. Do other changes in streams cause increases in stream temperature? The answer to this question is yes, other physical changes in the stream system can modify stream temperatures. Stream temperature is a product of complex interactions between geomorphology, soil, hydrology, vegetation, and climate within a watershed. Changes in these factors will result in changes in stream temperature. Human activities influence stream temperature by affecting one or more of four major components: riparian vegetation, channel morphology, hydrology, and surface/subsurface interactions. Stream systems vary substantially across the landscape, and site-specific information is critical to understanding stream temperature responses to human activities. How can apparently healthy fish populations exist in streams with temperatures higher than laboratory and field studies would indicate as healthy? Workshop participants identified several mechanisms that might explain the ability of fish populations to exist at higher than expected temperatures. The first mechanism was that the fish may have physiological adaptations to survive exposures to high temperatures. A second possibility was that stream habitats may contain cooler microhabitats that fish can occupy as refuge from higher temperatures. A third consideration is that ecological interactions may be different under differing thermal conditions resulting, for example, in changes in disease virulence or cumulative effects of stressors. Finally, since substantial differences exist between laboratory and field studies, it is difficult to apply results of laboratory studies to fish responses in the field. It is important to note that these proposed mechanisms are speculative and, as the list of gaps indicates, substantial experimental work is required to establish their influences on fish in different stream systems. Workshop Summaiy Workshop participants recognized gaps in the available science. Additional knowledge about human influences on stream temperatures and, consequently, influences on cold-water fish populations, will improve our ability to prevent further degradation of stream habitat and will enhance efforts geared towards the recovery of depressed fish populations. Even with these gaps, there was enough agreement on factors that influence stream temperature to indicate information is available to start developing and implementing management practices that are designed to reduce stream warming. It was suggested that managers should consider riparian vegetation, channel morphology, and hydrology, and should account for site differences.

  	Citation × Citation Citation Abstract Copy Title: Reclamation accomplishments, 1905-1953, Klamath Project, Oregon-California Author: Strantz, Maurice K. Year: 1953, 2005 SUMMARY AND CONCLUSIONS Klamath Project is a $13 million Federal investment in water resource development, About 200,000 acres are irrigated and gross crop production (has exceeded $17 million each year over the past 7 years. The Project encompasses the largest single block of irrigated land in the area and includes nearly half the three-county total irrigated area and one quarter of the cropland. Agriculture and manufacturing directly contribute half the three-county personal income and provide half the jobs. Klamath Project accounts for five-sixths of the gross income from crops, and half the total agricultural production in the three-county area. Personal income from project crops is estimated at $10.6 mil1ion in 1948. Recent crop production on the project supports directly or indirectly about $25 million in local personal income. Federal contribution for irrigation to repay costs without interest to date amounts to about $10.8 million. Annual personal income generated by project in the postwar years equals this assistance Project gross crop production of nearly $300 million over 46 years. Project farm income supports substantial portion of area retail trade and contributes to transportation and other services. Project agriculture in past 10 years increased its support to the economy and has helped offset the declines in the lumber industry. Without the project only about 50,000 irrigated acres would have been developed and the agricultural economy would have produced crops worth only about l/7th as large as at present. Reclamation development tends to maintain a stable prosperous economy in the three-county area.

Bureau of Reclamation Year: 1948, 2004 Public Notice No. 47 of August 27, 1948, was prepared in conformity with recommendations for a standardized procedure made at the Salt Lake conference in March 1948; it opened to public entry 86 farm units embracing 8,283 acres of irrigable land. Of nearly 24,000 application blanks sent out, 5,072 were returned during the simultaneous filing period. A five-man examining board placed 4,911 in the first priority group, 69 in the second priority group and rejected 91. The Regional Director reversed the action of the examining board in two instances making a total of 4,913 participating in the drawing. Applications were received from 39 states, the District of Columbia and the Territory of Alaska. California supplied 50% of all applications considered in the first priority group; Oregon supplied 27%; Utah supplied 6%; and the rest of the states supplied the remaining 17% The examining board interviewed 94 persons of 104 who were notified to appear for personal interviews after the drawing. Of those appearing for interviews, five refused to accept units in area "A" and three were rejectees whose appeals were later denied by the Regional Director. Of the ten who failed to appear for interview, five relinquished their award in writing; four were relegated to the end of their priority list, and one was the victim of an airplane accident. As the result of the drawing and subsequent interviews, 1.4% of the applicants from California 2.5% of the applicants from Oregon and 1.3% of the remaining applicants from other states were awarded farm units. Ten of the 39 states, from which applications were received, were represented in the settlement of the 86 farm units. Of the 23 who selected units in area "A", only two availed themselves of options to lease additional land in the Tulelake sump area* Apparently, because of high rental fees, the majority of the area "A" settlers could not afford to lease lands supplemental to their homestead. Therefore, since the development of area "A" lands will be a costly procedure, it is possible that in the future there may be cases of relin-quishment of units due to the homesteaders' inability to meet expenses. First unit was awarded on March 9, 1949; the last unit was awarded on June 20, 1949.

The Lost River sucker {Deltistes luxatus) is a federally listed, endangered fish species endemic to Upper Klamath Lake?a large, shallow hypereutrophic lake in southern Oregon. Sucker population declines in the lake over the past few decades are thought to be partly attributable to extreme water quality conditions, including elevated ammonia concentrations and elevated pH, that occur during summer cyanobacterial blooms. I analyzed structural changes in gills of larval Lost River suckers after they were exposed to elevated pH and elevated ammonia concentrations in chronic toxicity tests conducted in the laboratory. Histopathological changes in sucker lamellae were observed at ammonia concentrations that did not significantly decrease survival, growth, whole-body ion content, or swimming performance. Structural changes that I evaluated included O2 diffusion distance, lamellar thickness, hyperplasic and hypertrophic mucous cells, and infiltration of white blood cells into the lymphatic space. The increases in diffusion distance and lamellar thickness were statistically significant (P < 0.05). These gill changes are indicative of potentially compromised respiratory and ionoregulatory capacity. Because in this species gill structural changes appear to be a more sensitive indicator of stress in eutrophic water quality conditions than are the more traditional sublethal indices, gill histopathology might be useful for monitoring the health of Lost River suckers in Upper Klamath Lake.
