| Description | Located in Kittitas and Yakima Counties, the upper Yakima River basin extends from headwater areas near Snoqualmie Pass, downstream to the more arid regions near the cities of Ellensburg and Selah. In 2002, the Department of Ecology established a Total Maximum Daily Load (TMDL) for suspended sediment, turbidity, and organochlorine pesticides in the upper Yakima River basin. Turbidity targets and total suspended sediment (TSS) load allocations were established as part of this TMDL. The TMDL also included a detailed implementation plan to improve water quality in the basin. In 2019, Ecology conducted extensive monitoring to see if the levels of TSS and turbidity in the upper Yakima River basin were meeting the final target levels set by the TMDL. This 2019 effectiveness monitoring study found that the Yakima River and most of its tributaries met the TMDL targets for turbidity and TSS load allocations for the critical period of April-October 2019. These results indicated that TMDL implementation shows success, but Wilson Creek and Sorenson/Fogarty sub-basins continue to need additional improvement. |
