e SAHS KNOB DAM AND RESERVOIR PLAN DESCRIPTION Sams Knob Dam and Reservoir would be a new structure located on Snowmass Creek a tributary of the Roaring Fork River. Figure 1 shows the general reservoir location. The sponsoring entity for the dam and the contact person are: Snowmass Water and Sanitation District Richard Wall, Manager 923-2056 P.o. Box 5700 Snowmass Village, Colorado 81615 e The water would be used for domestic, municipal, irrigation, recreational, industrial and other beneficial purposes in the Snowmass District service area and for snow making at the Snowmass Ski Area. There is also some potential for providing instream flow releases. This reservoir is the only proposed source of significant raw water storage capacity in the snowmass Creek basin for District operations. The water from the reservoir would be diverted into an adjacent drainage where the District' s water treatment plant is located. Diversion of the water to another stream is not popular with the residents in the Snowmass Creek drainage r however the construction of Sam' s Knob Reservoir was contemplated in the 1978 Intergovernmental Agreement which was ratified by the pitkin County Commissioners, the Snowmass Water and Sanitation District Board and the Snowmass Land Company. The District has had initial engineering plans prepared. The information obtained for the evaluation herein was a 1 inch equals 50 foot topographic map with the embankment superimposedr and elevation-area-capacity curve. The District has cursory information on the dam and reservoir, this report is mainly an attempt to bring the project to the forefront so that issues can be resolved and the construction initiated. This reconnaissance report describes the engineering issues, preliminary designs, and costs of constructing the dam. Sams Knob Dam I
