<br />- OOIl~)21 <br /> <br />Specific water rights used at the Henderson Mill include the following: <br /> <br /> AMOUNT ADJUDICA TlON APPROPRIATION ADMIN, II <br />NAME IAFI DATE DATE NO. <br />Honderson Mine Water System 704 08-03-1911 VllIri08 Varies <br />Ute Park Reservoir Right 2.100 09-08-1954 38238,00000 <br />Cabin-Moadow Creok Agreement 3.000 Usos Donver Water Rights Varies Varios <br /> <br />In order to simplify the CROSS modeling effort, it is recommended that the <br />Henderson Mill diversions be modeled as a single diversion at the Williams Fork Pump <br />Station. This aggregated node should be in the amount of 8.8 cfs (the capacity of the <br />pump station) with a recommended Administration Number of 31359.00001, a value that <br />is slightly junior to Denver's Williams Fork Reservoir. This assumption may tend to slightly <br />understate the yield which could be realized from the more senior "Henderson Mine Water <br />System" (volumetrically limited to no more than 704 acre-feet annually), but is a <br />reasonable approximation. As necessary, when this aggregated water right is out of <br />priority with respect to Denver's water rights for the Williams Fork collection system, the <br />diversions should be augmented using the water available in Henderson's 3,000 acre-foot <br />account in the Meadow Creek Reservoir (Cabin-Meadow Creek Project). When the call <br />originates from the main stem of the Colorado River, the replacement should be from <br />Henderson's 2,200 acre-foot storage account in Williams Fork Reservoir. <br /> <br />From engineering studies provided by Henderson's water rights consultant, a time <br />series has been prepared which represents the historic deDletions to the Williams Fork River <br />attributable to the operations at the Henderson Mill during the CROSS study period, 1975 <br />through 1991. This historic time series has been incorporated into the CROSS WRPM <br />database. This time series represents depletions and as such there are no return flows <br />associated with the diversions. <br /> <br />M:\DOCUMENn 1332 .2\INDU5TRI.MEM <br /> <br />1-5 <br />
