HYDROLOGIC DATA <br />r1 <br />LJ <br />Inflow Design Flood <br />Inflow design floods for the Minnesota Dam were computed in accordance <br />with the procedures outlined in the Water Resources Technical Publication <br />entitled "Design of Small Dams", published by the Bureau of Reclamation, <br />United States Department of the Interior. This procedure is based on that <br />outlined in the Soil Conservation Service's "Hydrology Guide for Use in <br />Water Shed Planning". The resulting inflow design flood hydrograph <br />represents direct runoff from precipitation in the form of rain over a <br />water shed having no unusual runoff characteristics. An additional <br />• quantity of runoff due to snowmelt as determined in a similar water shed <br />analysis has been included. The following general procedure was used to <br />determine amounts of runoff. <br />Preliminary Data <br />The Minnesota Dam is located in Section 32, Township 13 South, Range 90 <br />West, in Gunnison County, Colorado. The drainage area terminating at the <br />Minnesota Dam consists of 5.5 square miles of foothill area and cliff area. <br />Figure 1 Minnesota Dam Drainage Map, illustrates the characteristics and <br />extent of the drainage area. <br /> <br />VI-9 <br />
