The state Department of Ecology is seeking input on a draft water quality improvement plan to reduce temperatures in certain portions of upper Yakima River tributaries.
Warm summer water temperatures cause many streams connecting to the upper Yakima River to fall short of Washington's water quality requirements. Fish such as salmon, steelhead and bull trout use the upper Yakima River tributaries as important migration routes and as spawning and rearing areas.
This water quality improvement plan describes sources of warm water pollution in a water body and how much heat the waters can accept and remain healthy. The plan also offers solutions to reduce pollution.
The public is invited to comment on the plan, which can be reviewed online or in person at public libraries in Ellensburg, Cle Elum and Roslyn. Copies of the plan can be requested by calling 509-454-7860.
