Water Quality Improvement Projects
Chehalis River Basin Area:

These organizations are involved in implementation of the water quality improvement and salmon recovery activities in WRIAs 22 and 23. Often times projects that are good for salmon recovery are also good for water quality, and vice versa, and these organizations have been collaborating for over a decade to make the Chehalis River Basin and Grays Harbor a great place to live, recreate, and do business.
