Description The Upper Chehalis watershed has been identified as a major source of fecal coliform bacteria to the Lower Chehalis watershed that includes Grays Harbor. Within the Upper Chehalis watershed, fecal coliform concentrations in excess of the water quality criteria are widespread.

A comprehensive evaluation of fecal coliform data in the Upper Chehalis River was completed, and target reductions were established for the mainstem segments of the Upper Chehalis River and its tributaries.

Implementation strategies recommended include (1) implementing and improving best management practices for nonpoint sources, (2) replacing failing on-site sewage treatment systems, and (3) developing a monitoring strategy to evaluate the effectiveness of the TMDL implementation measures.
