| Short Description |
The Walla Walla River tributaries have been selected for a temperature Total Maximum Daily Load (TMDL) study as required by the federal Clean Water Act. Data gathered at the Washington State Department of Ecology′s ambient monitoring stations were the basis for placing three stream segments on the 1998 303(d) list of impaired waterbodies. Additional studies by the Washington State Department of Fish and Wildlife, the Columbia Conservation District, and the Army Corps of Engineers show that high temperatures are prevalent throughout the basin.

| Abstract | Long Description |
The Walla Walla River tributaries have been selected for a temperature Total Maximum Daily Load (TMDL) study as required by the federal Clean Water Act. Data gathered at the Washington State Department of Ecology′s ambient monitoring stations were the basis for placing three stream segments on the 1998 303(d) list of impaired waterbodies. Additional studies by the Washington State Department of Fish and Wildlife, the Columbia Conservation District, and the Army Corps of Engineers show that high temperatures are prevalent throughout the basin. Stream temperatures can affect an organism′s ability to live or reproduce and may compromise usage by Steelhead and Bull Trout which are listed as threatened under the Endangered Species Act. Data collection, consisting of continuous temperature monitoring, thermal infrared imagery (TIR), stream flow monitoring, riparian surveys, and an extensive groundwater study is planned for the summer of 2002. Ecology is working cooperatively with the Washington State Department of Fish and Wildlife and the Walla Walla Technical Workgroup (TWG) to coordinate field work. Water temperature in the tributaries will be characterized and load and wasteload allocations established for heat sources to meet water quality standards. |
