Groundwater budget components for San Juan County, Washington

This data release contains estimates of the inflow and outflow components of a groundwater budget for San Juan County, Washington, and includes a Soil-Water-Balance (SWB) model used to estimate groundwater recharge, bias-corrected output from the SWB model, and detailed water use estimates. Groundwater recharge estimates were calculated by bias correcting SWB model net infiltration output using a recently published regional SWB bias correction surface. Water use estimates for public supply, self-supply, and agricultural irrigation were computed based on publicly available data from Washington State Department of Health, Washington State Department of Ecology, Washington State Department of Agriculture, USGS county level water use estimates, and Washington Geoservices. These data were combined into groundwater budget tables that summarize the groundwater inflows and outflows for San Juan County as a whole and individually for the four largest islands in the County (Lopez, Orcas, San Juan, and Shaw).
