The Issue: Groundwater is an important resource for domestic, commercial, and industrial usage in Mason County, 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, and the potential effects of future natural conditions and anthropogenic activities on groundwater resources are not well understood in the watershed. Additional information is required to help ensure the long-term sustainability of the area's groundwater resources.
How USGS will help: The USGS will establish and operate of a network of monthly groundwater-level and synoptic stream baseflow measurement sites. It is anticipated that these data will be integrated, along with other information, into a numerical flow model to contribute to an improved understanding of water resources in Mason County.
