|Description||This report uses the results of a study (Mid-Yakima River Basin Fecal Coliform Bacteria Total Maximum Daily Load: Water Quality Study Findings), published in September 2012, in order to develop (1) appropriate target reductions for bacteria pollution, and (2) an implementation plan that lays out roles and responsibilities for the cleanup process. In 2018, Ecology adopted new State WQS for bacterial indicators to transition from FCB to enterococci bacteria (E. coli) requirements by December 31, 2020 (pub number 18-10-029).
High bacteria pollution within the various surface waters of the Mid-Yakima River Basin Bacteria TMDL project area does not allow for safe primary contact recreation by the general public. All surface waters need to comply with current State WQS to ensure the general public’s quality of life, as well as to ensure sustainable local and regional economic development. The TMDL will specifically reduce bacteria pollution within the Cowiche Creek, Moxee Drain and Wide Hollow Creek sub-basins.
