The water in Chatfield is of poor quality and must be pumped to Marston <br />treatment plant. However. when faced with a serious drought situation, these quality and cost <br />concerns become less important than the need for supply. <br /> <br />('hatfield oPc'ration" \,'ill ["eyer! to tht' non-Jroll~hll('rnb ~,r the] ()7() colllral'1 once Dt'Il\'er Water <br />ha.., tL'rrllinClled ih Jroll~ht response pbn. <br /> <br />6. Denver Water's Refill Proposal <br /> <br />Once Chatfield goes below 5423. the question becomes how it would be refilled tn that lei d <br />State Parks would like it to be refilled before the next recreation season. However. that simply is <br />not practical or reasonable. Despite its recreational value. Chatfield has an exorbitant rate of <br />evaporation and water there is largely unavailable to Denver Water. Deliberately placing water <br />there when our municipal supply system is already devastated would be wasteful and foolish and <br />contrary to Denver Water's charter obligation to provide municipal supply. <br /> <br />It is important to remember that although the drought may start to ease, conditions could again <br />worsen. Once the drought begins to lessen, Denver Water must operate its reservoirs in a <br />manner that assumes another drought may begin. Denver would attempt to refill its primary <br />reservoirs of Dillon, Cheesman, and Gross first to help prepare for another drought event. These <br />three reservoirs have senior water rights, low evaporation rates. and permit high quality water to <br />enter our treatment plants. <br /> <br />4 <br /> <br />Deleted: recre.alIOI1 al Chalfleld wpuld <br />also be affecled <br /> <br />Deleted: the pumps <br /> <br />j Formatted Table <br />
