Spokane County, in conjunction with Stevens and Pend Oreille Counties, evaluated the use of a tri-county water bank to address existing and potential regulatory constraints on existing and new water use, in Water Resource Inventory Area (WRIA) 55, the Little Spokane Watershed.
The feasibility study was completed in June 2015. Spokane County has since developed a water bank for a portion of WRIA 55, but it does not extend into Pend Oreille or Stevens Counties.
