The Issue: Groundwater is an important resource for domestic, commercial, and agricultural usage in the Little Spokane River Basin, and groundwater discharge helps maintain streamflow in area streams. Consequently, as the population grows, and commercial and agricultural activity increase, so does the demand for groundwater. However, the quantity of usable groundwater, and the potential effects of changes in climate or human activities on groundwater resources, as well as potential impacts to streamflow, are not well understood.
How the USGS will help: The USGS, working in collaboration with Spokane County Water Resources, will collect and analyze the information necessary to describe the groundwater system of the Little Spokane River Basin including mapping the extent and thickness of major aquifers and describing directions of groundwater movement. This and other information will provide the basis for future computer modeling of the ground- and surface-water systems of the basin that will aid in water management decisions.
