<br />Self-Supplied Water Use Information <br /> <br />Average Annual Water Demand for Snowmaking <br /> <br />Two dozen regional water use studies were reviewed to identify estimates of <br />current and future projected water demand for snow making in Colorado <br />counties. Data useful in quantifying and projecting snow making water use <br />was found in: <br /> <br />. Hydrosphere Resource Consulting, Inc. (HRC Inc.), Upper Colorado <br />River Basin Study, Phase II, Final Report, May 2003. <br /> <br />The HRC Inc. findings for" current" and" future" water use attributed to <br />snowmaking are shown in Table 8 for the years 2000 and 2030, respectively. <br />The increase in future, or year 2030, water use for snowmaking accounts for <br />planned expansion of runs at each facility. <br /> <br /> TABLE 8 <br /> ESTIMATES OF CURRENT <br /> AND FUTURE SNOWMAKING AT SELECTED <br /> COLORADO SKI AREAS <br /> Estimated Average Annual Water Demand <br /> for Snowmaking in Acre-feet <br />County Snowmaking Facility 2000 2030 <br />Grand Winter Park Rec. 199 477 <br />Gunnison Mt.

Crested Butte Ski Area. <br /> <br />In addition, BBC Research & Consulting provided supplemental information <br />that permitted separation of data by county from their Yampa Valley Water <br />Demand Study (1998). This provided the water use estimates for <br />smowmaking in Routt County. <br /> <br />A list of ski areas in Colorado was obtained and each identified ski facility <br />was contacted by phone to verify the county location and to ask if <br />snowmaking occurred at that facility. The resulting number of snowmaking <br />ski facilities by county is shown in Table 9. The numbers of snow making <br />facilities in each county are based solely on conversations with various <br /> <br />III. Data Collection andAnalysis <br /> <br />21 <br />
