This dataset presents recharge rates (mm/year) of the Gulf Islands aquifers in British-Columbia. Recharge to groundwater is based on regional modeled precipitation (from Climate BC's PRISM data for 1961 - 1990 period), and assumptions about evapotranspiration using analytical formula. Recharge to groundwater was estimated as in range of 103 to 178 mm/year.
This map was created to provide a regional frame of the spatial distribution of the recharge within the Gulf Islands.
