This dataset was created for the Black Hills Hydrology Study (BHHS). The BHHS is a long-term investigation that was initiated in 1990 as a cooperative effort between the U.S. Geological Survey (USGS), the South Dakota Department of Environment and Natural Resources (DENR), and the West Dakota Water Development District. West Dakota represents various local and county cooperators. The purpose of the study was to assess the quantity, quality, and distribution of surface and ground water in the Black Hills area of South Dakota (Driscoll, 1992). The study area includes parts of Butte, Custer, Fall River, Lawrence, Meade, and Pennington Counties in South Dakota. Data from Crook and Weston Counties in Wyoming also are included. Reviews_Applied_to_Data: This digital coverage was subjected to the same review standard that applies to all U.S. Geological Survey reports. Reviewers were asked to check the topological consistency, tolerances, attribute frequencies and statistics, projection, and graphic extent. The reviewers checked the metadata files for completeness and accuracy.

Chain-node topology present. This data set consists of contours of equal average annual yield efficiency for water years 1950-98 in the Black Hills of South Dakota and Wyoming. Contours were plotted on paper using point data.

The stations used in contouring are presented in Carter, Driscoll, and Hamade (2001). The contours were digitized from the paper version. A GRID of average annual precipitation for water years 1950 through 1998 was generated from point data using an inverse-distance weighting method described in Driscoll, Hamade, and Kenner, 2000. The GRID was used to generate contour lines representing equal average annual yield efficiency. The arcs were clipped to the Black Hills Hydrology Study area boundary on the east, north, and south, and were roughly clipped to a map area on the west. 2001 Vector Complete chain 28 Point 35 Universal Transverse Mercator 13 0.999600 -105.000000 0.000000 500000.000000 0.000000 coordinate pair 0.000256 0.000256 meters North American Datum of 1927 Clarke 1866 6378206.400000 294.978698 sd_re5098.aat Arc attribute table ARC/INFO FNODE# Internal node number for the beginning of an arc (from-node).
