Know Your Watershed

The 1998 legislature passed Ch. 90.82 RCW, to set a framework for developing local solutions to watershed issues on a watershed basis. Ch. 90.82 RCW states that the legislature finds that the local development of watershed plans for managing water resources and for protecting existing water rights is vital to both state and local interests.

Six Department of Ecology Water Resource Inventory Areas (WRIAs) are within Spokane County.

The County is the lead agency for WRIA 55/57 - Little and 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.
