Abstract: This dataset represents an estimated representation of net annual recharge of surficial aquifers in Wyoming 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 500 meter cell size. For more details about this dataset, please refer to this report: Hamerlinck, J.D. and Arneson, C.S., editors, 1998, Wyoming Ground-Water Vulnerability Assessment Handbook: Volume 1. Background, Model Development, and Aquifer Sensitivity Analysis: Spatial Data and Visualization Center Publication SDVC 98-01-1, University of Wyoming, Laramie, WY.
Purpose: This layer 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. This layer was specifically developed to aid in small-scale regional analysis within Wyoming and is not suitable for site specific analysis.

Usage Constraints: This data should not be used for analysis at a scale larger than 1:500,000. Because updates to this dataset or the attached metadata will occur without notice, this dataset may not be redistributed or repackaged in any form without the express written consent of the University of Wyoming Spatial Data and Visualization Center. Instead it is recommended that additional users download the most current version of the data from http://www.sdvc.uwyo.edu/clearinghouse.
