Spokane River Watershed Advisory Committee

The Spokane River Watershed Advisory Committee page is devoted to all things associated with water quality in the Spokane River Watershed.

Spokane River Toxics Advisory Committee

The Spokane River Toxics Advisory Committee, or SRTAC, is a forum for issues related to toxics in the Spokane River Watershed. 

The SRTAC is an Ecology led advisory committee that includes membership representing state agencies, local governments, tribes, environmental groups, consultants and other local concerned community members. Typical discussion topics include new and existing toxics in the Spokane River watershed and how to address and potentially mitigate those toxics. 

Meetings

The SRTAC meets on the 4th Wednesday of every month from 1-3:30pm and offers a hybrid meeting option.  Virtual attendance is via Zoom and a link is provided through the meeting invite for each meeting. The in-person meeting location is held at the Spokane County Water Resource Center.
