exceed the actual diversions that occurred during the dry years of the 2002 - 2003 study <br />period, and reflect the recent maximum historical diversion that may occur in the future <br />during such a future drought event under diligent operation of the downstream water <br />rights. It is noted that these maximum historical values are frequently less than the <br />maximum decreed rates of flow for the diversion structures. <br />DEMAND SIDE SCENARIOS <br />The Demand Side Scenarios (DS Scenario) are used to examine current and <br />projected District demands as well as raw water storage requirements in relation to the <br />available supply and meeting the Snowmass Creek Stream Flow Stewardship Goal by <br />supporting, through reduction of diversions, a minimum level of flow in Snowmass Creek <br />below the District's Snowmass Creek pump station. Additional assumptions and <br />conditions are discussed below. <br />Current Storage. The current treated water storage available to the District is <br />about 16 acre feet (5.2 MG). Wheeler assumed that none of this storage would be <br />utilized to assist in meeting Stream Flow Stewardship Goals or demand shortfalls other <br />than short term peaking usage. <br />Raw Water Storage Requirements. The raw water storage capacity required to <br />meet District demand and the Stream Flow Stewardship Goal are determined for each <br />operational scenario. It is noted that additional raw water storage would be required to <br />provide for storage reduction due to evaporation and seepage losses, as well as a <br />possible dead storage pool, that are expected to occur with a raw water reservoir. <br />Storage Reserve for Catastrophic System Failure. The model analyses are <br />developed on the assumption that the District's Snowmass Creek and East Snowmass <br />Creek delivery systems are usable on a day-in day-out basis. It is conceivable that a <br />catastrophic event, such as landslide, flood or forest fire could significantly damage <br />either or both delivery systems, or render the water being delivered untreatable. These <br />systems could remain out of service for an indeterminate period of time, leaving the <br />District with only its water storage facilities located within Brush Creek drainage.
