Included in this section is a description of how the alluvial M &I pumping was identified <br />and how the records of historic pumping were obtained. The work described in this section <br />was undertaken under Task 30 of the SPDSS project. <br />Several steps were taken to identify M &I wells and historic pumping in the South Platte <br />Alluvium Region. These include a query of HydroBase, selection of the higher - production M &I <br />entities, and contacting these entities to collect historic alluvial pumping data. These steps are <br />described below. <br />First a water rights query of HydroBase was performed using the DSS tool StateView, to <br />identify all Division 1 wells completed in the alluvium. Then the 'use type' field was used to <br />identify wells that have a Municipal, Industrial or Commercial use code, which are the three use <br />types that define M &I uses for this evaluation. Many of the wells have multiple use types <br />listed; therefore, for the purposes of this analysis, it was assumed that the primary use of a well <br />is represented by the first use code provided. Since a portion of the South Platte Alluvium <br />Region study area is located in the Kiowa -Bijou and Lost Creek Designated Basins, where water <br />rights information are not readily available, a similar query of the well permit database was <br />performed in those geographic areas. The final step was to identify alluvial M &I wells located <br />within the study area. This was done by linking the queried wells to the shapefile of Division 1 <br />decreed wells. <br />In consultation with the State it was determined that this task should focus on M &I wells that <br />pump at more than 50 gpm and M &I entities that have a total decreed rate or, for the <br />Designated Basins, a total permitted pumping rate of at least 1000 gpm. These entities were <br />SPDSS Phase 3 Task 41 TM -Final <br />02/08/2007 <br />2 <br />
