Six Department of Ecology Water Resource Inventory Areas (WRIAs) are within Spokane County.
The County is the lead agency for WRIA 55/57 - Little & Middle Spokane River, and WRIA 54 - Lower Spokane River. The County is a member of and actively participates in the WRIA 56 - Hangman Creek and WRIA 34 - Palouse Planning Units. The County does not currently participate in WRIA 43 - Upper Crab Creek due to the small portion of the WRIA with the County. Click on the map below to go to the respective planning units webpage.
