Pacific Northwest salmon rely on many interwoven factors to maintain their health, well-being, population, and distribution. Abnormal conditions in a fish's environment may elicit a stress response. If a fish is already responding to one stressor, it is less likely to withstand another. Temperature can be a biological, physical, or chemical stressor. Biologically, temperature affects the metabolism of fish and their ability to resist disease. Physically, temperature affects properties of water and fish's tolerance to suspended sediment. Chemically, temperature can change the concentration of substances in water and reduce a fish's ability to withstand chemical exposure. Not all these relationships are well understood, but they need to be considered when developing a temperature standard. This issue paper reviews biological, physical, and chemical properties related to temperature within salmonid ecosystems.
"May 2001". The Project workgroup consists of individuals from U.S. Environmental Protection Agency (Region 10), U.S. Forest Service, Washington Department of Ecology, National Marine Fisheries Service, U.S. Fish and Wildlife Service, Columbia River Inter-Tribal Fish Commission, Idaho Department of Environmental Quality, U.S. Geological Survey, and Oregon Department of Environmental Quality.
"The technical workgroup developed five technical summaries on the major physical and biological considerations for developing water temperature standards: 1. thermal effects on salmonid physiology, 2. thermal effects on salmonid behavior, 3. interactions between multiple stressors... affecting salmonids, 4. thermal influences on salmonid distribution, and 5. spatial and temporal variation in patterns of stream temperature." -- Preface.
