Description Previous monitoring within the Yakima River boundary waters of the Yakama Nation Reservation (Union Gap to Mabton) has shown that the Yakima River can have high water temperatures and low dissolved oxygen (DO) levels that do not protect fish and other aquatic life that depend on cool, oxygenated water.

This project coordinates the collection of water quality data in support of USGS continuous water quality monitoring that is being conducted at several Lower Yakima River locations during 2022. The U.S. Bureau of Reclamation, along with the Yakima Basin Integrated Plan and the Benton Conservation District, is sponsoring water quality monitoring gages to provide calibration data in order to construct a water quality model that simulates water temperature and DO. The model will be used to assess different water management strategies to improve fish migration in the Yakima River corridor.

Sampling will occur from June through November 2022, capturing data for critical periods during the irrigation season, as well as some post-irrigation periods. Sampling will take place every two weeks at 10 locations within the Lower Yakima River basin.
