Estimated Net Annual Aquifer Recharge - Bear River Basin (2011)

This dataset represents an estimated representation of net annual recharge of surficial aquifers in the Wyoming Bear River basin from natural sources. Irrigation or other man-made recharge structures are not represented. Estimated recharge is calculated using a simplistic formula based on soil type and average annual rainfall. The dataset is in raster format with 100 meter cell size. The recharge dataset was developed specifically to aid in the creation of a Wyoming ground-water vulnerability to surface contamination study conducted at the Wyoming Water Resources Center. The DRASTIC-based model requires surficial aquifer recharge as one of its parameters.
