Coverage of the snowmaking system will nearly double when the North Mountain ski area is developed. Also, a 3 MG storage reservoir may be developed for snowmaking use, to reduce instantaneous diversions from the river. Crested Butte Mountain Resort holds an absolute decree of 4.55 cfs (2.9 MGD) and a conditional decree of 1.45 cfs (0.9 MGD) for snowmaking on Crested Butte Mountain. Both decrees were adjudicated in 1981, which makes them senior to the State's instream flow rights. CBMR's snowmaking operation is covered under a Forest Servi$ special use permit. According to the terms of an agreement reached among the Colorado Division of Wildlife, CBMR, and the Forest Service, CBMR is required to limit its diversions, when necessary, in order to maintain a minimum instream flow of 7.0 cfs in the East River below the CBMR pumping plant. CBMR holds a conditional water right for snowmaking on Crested Butte> North Mountain in the amount of 5.0 cfs (3.2 MGD) which was adjudicatfJd in 1982. CBMR is limited to making its diversions between October 1 and April 30 in its snowmaking decrees. Skyland Water Supply The Skyland development and resort, located southeast of the town of Crested Butte, has its own water supply system, operated by the Skyland Metropolitan District. The Qistrict currently serves about 40 homes in addition to a 50 unit lodge and clubhouse. The system is fed by Decker springs with the collection system located on the southwest side of Crested Butte Mountain. The water right for the system is for 1.875 cfs (1.2 MGD). which was adjudicated in 1924. Water is collected in a wetwell, then chlorinated and pumped into a distribution system. The s~stem provides about 0.06 MGD in summer and 0.025 MGO in winter and has. about 0.025 MG of raw water storage and 0.25 MG of treated water storage. Plans call for 5PO ERU's and a population of about 1,750 at buildout. Future expansion of tl'le water supply system will be needed to satisfy this population as well as fire figt;lting needs. Backup wells and additional augmentation may be needed at full buildout especially in dry years. 59 L lo.t ,;; .Ii. 'b<C~'.ci;"""". ~- ...; " -,-
