The Lower Spokane River Watershed

< N E W S >


Watershed Planning under RCW 90.82 is being conducted in the Lower Spokane River Basin. The Spokane River system is tributary to the Columbia River and extends from Washington State into Idaho State. Water Resource Inventory Area (WRIA) 54 is the portion of the Spokane River beginning at the confluence with Hangman (Latah) Creek, and extending some 70 miles to the Lake Roosevelt portion of the Columbia River.

Spokane County is the lead agency and one of the initiating governments. Members of the Planning Unit include broad representation of interests within the basins and hold monthly meetings that are open to the public.

The watershed planning effort has produced a variety of information management challenges. This web site provides an overview of the project for the interested public and also provides access to project management and technical resources for project team members.

Please send requests for further information by mail or email to Spokane County, the lead agency. The mailing address for Spokane County is:
