Water Quantity Research
Water Bank Feasibility Study
Spokane County, in conjunction with Stevens and Pend Oreille Counties, is evaluating the use of a 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.
West Plains Hydrogeologic Framework
The main water source for the West Plains are aquifers found in the Columbia River Basalt Group (CRBG) formations, overlying sediments, and interbedded sediments.
WRIA 55 / 57 Wetland Restoration & Storage
Spokane County Water Resources is managing a study to investigate methods to increase surface water stream flow in WRIAs 55 and 57 during low flow summer months.
West Plains Geophysical Orientation Study
Geophysical methods can measure physical properties at the ground surface and the data used to infer the composition of the subsurface.
Water Availability Standard
A work group of local stakeholders including local government, home builders, developers, hydrogeologists, realtors and environmental groups is meeting to develop recommendations for consideration by local decision makers.
Little Spokane Groundwater Inventory & Mapping
The goal of the Little Spokane Groundwater Inventory and Mapping project is to develop a database of available information in tabular and GIS formats for use in intermediate estimates of water use, recharge, well yields and eventual use in the development of a numerical groundwater flow model.
Water Demand Forecast Model
In 2010 Spokane County Water Resources in conjunction with the consulting firms Tetra Tech and CDM developed a Water Demand Forecast Model. The model is capable of forecasting demand for numerous water use sectors, at various spatial scales and time horizons.
