Groundwater is an important resource for domestic, commercial, and industrial usage in the Puyallup River Watershed, and groundwater discharge helps maintain late-summer and early-fall streamflow (baseflow) in many area streams. Consequently, as the population grows, and commercial and industrial activity increase, so does the demand for groundwater. However, the quantity of usable groundwater, the potential effects of future natural conditions and anthropogenic activities on groundwater resources, and potential impacts of groundwater withdrawals on streamflow, are not well understood in the watershed. Additional information is required to help ensure the long-term sustainability of the area's groundwater and surface-water resources.
