    Introduction This project is a portion of the effectiveness monitoring phase of the Upper Yakima River Basin Suspended Sediment, Turbidity and Organochlorine Pesticide Total Maximum Daily Load (TMDL). The objective of this TMDL is to reduce sediment, turbidity and organochlorine pesticides in the upper Yakima River and its tributaries during the period from April through October. In this effectiveness monitoring project, only turbidity and suspended sediment levels will be evaluated; the organochlorine pesticide levels will be assessed in 2007.

    Background and Problem Statement The upper Yakima River basin is located in south-central Washington State, and drains 2,139 square miles on the eastern slope of the Cascade Mountains. Land uses in the basin vary from forestland, range, and intensively irrigated agriculture to urban and suburban areas. A network of supply canals, diversions, and irrigation return drains are located all along the upper Yakima River basin, but are especially concentrated in the lower Kittitas Valley. Water from the Yakima River and the streams flowing through the valley is directed through the irrigation network. The primary monitoring and assessment area consists of the mainstem Yakima River and its major tributaries from RM 121.7 (Harrison Bridge, near the town of Selah) upstream to RM 191 (4.5 miles northwest of Cle Elum on Interstate 90). The Clean Water Act directs the Washington State Department of Ecology (Ecology) to perform a total maximum daily load (TMDL) analysis for contaminated waters on the state’s 303(d) list of impaired waterbodies. Ecology determined that suspended sediment and associated turbidity, as well as DDT and dieldrin, represent key water quality impairments in the upper Yakima River. The control of suspended sediment generation and transport during the period from April through October will result in far-reaching water quality and fish habitat improvements in the upper Yakima Basin.
