      Description:
        Abstract:
          Digitized from (Hurr and Schneider, 1972) for each reach in
          the South
          Platte River Basin by Mario Mejia-Navaro with the IDS Group
          at CSU. Stream depletion factors are an estimate of how
          long water withdrawn from a well will take to deplete the
          river. These values are routinely used to determine when
          the effect of a well will be experienced in the South
          Platte River. Once
          this coverage was digitized and edited for errors, the
          South Platte River was added with a SDF value of 0.
          ARC/INFO was used to generate a Triangular Irregular
          Network (TIN) line coverage using ARC/TIN. The TIN coverage
          was used to generate SDF isolines for every ten days. The
          resulting coverage was then split into small segments and
          converted to the GIS GRASS (Geographical Resources Analysis
          Support System) to generate 40 meter (0.59 acres) grid
          resolution raster maps. These raster maps were then joined
          for each Water District and exported back to ARC/INFO for
          display. The resulting coverages for each Water District in
          Water Division 1 show an SDF value for each acre in the
          South Platte River Basin. These values will be used to
          assign SDF values for each well in the basin. As the
          location of the wells improves the accuracy of the SDF
          values assigned to them will also be improved. Technical
          questions and comments can be addressed to the IDS Group at CSU.

        Supplemental_Information:
          This coverage is not an official coverage from the state
          but a work product developed by the Integrated Decision
          Support Group (www.ids.colostate.edu) as part of a project
          funded by a number of water user organizations.
