District demands, with the most likely source being raw water storage in the form of <br />reservoir storage. <br />RESERVOIR OPERATIONS <br />The District currently has treated water storage of 5.2 MG (approximately 16 ac- <br />ft), estimated to provide about 3 days of District municipal water usage. For the study <br />analyses, the District's future raw water storage capacity requirements are determined <br />as additional volumes required above the existing capacity. Utilization of the District's <br />treated storage in order to meet the Snowmass Creek Stream Flow Stewardship Goal is <br />not recommended, as this could deplete required fire and short-term emergency <br />supplies should a delivery system catastrophe and reduced treated storage volumes <br />occur simultaneously. <br />Raw water storage is operated on the assumption that if there is water in storage, <br />and the Stream Flow Stewardship Goal is not being met, the raw storage water will be <br />used in lieu of Snowmass Creek diversions, thereby supporting the stewardship goals <br />for Snowmass Creek to the level being modeled (i.e., the Stream Flow Stewardship <br />Goals). Support levels are limited to the amount of water diverted by the District from <br />the Snowmass Creek basin, i.e., water from a raw water storage reservoir is used in the <br />District's municipal system in lieu of Snowmass Creek diversions, but is not released to <br />augment Snowmass Creek streamflow. <br />Upon examination of initial model runs it was found appropriate to start the model <br />assuming the raw water storage reservoir(s) are full on June 1 st of 1977 for the 1977 <br />analysis and on January 1 5t of 2002 for the 2002 - 2003 analysis. <br />Page 13 <br />
