The reservoir is owned and operated by the Lone Cone Ditch and Reservoir Company. However, the sponsor of the proposed reservoir enlargement is the San Miguel Water Conservancy District. The reservoir, which has a capacity of 1800 acre-feet, is operated in conjunction with the Lone Cone Ditch to serve irrigated lands in the Norwood and Redvale area. Lone Cone Reservoir has decreed water rights on Naturita Creek to the extent of 2940 acre-feet. All of these water rights are absolute, except for 675 acre-feet. Problem The existing Lone Cone Reservoir serves about 5000 acres of farm land in the Norwood-Redvale areas. These irrigated lands need supplemental, late season irrigation water. Feasibility Study In January, 1984, the San Miguel Water Conservancy District applied to the Board for financial assistance to enlarge Cone Reservoir. The Board subsequently authorized 50 percent funding for a feasibility study on the proposed project. The study has now been completed by Western Engineers, Inc., a Grand Junction consulting engineering firm, and is the basis of the recommendations on the project. Proposed project The project, as proposed, would involve raising the existing embankment ~ by 19 feet, with the necessary changes to the spillway, outlet works, drains and riprap. The raising of the embankment would increase the reservoir's capacity from 1,800 acre-feet to 5,800 acre-feet. The proposed enlargement would provide supplemental water to about 4,880 acres of the presently irrigated land. 721 In/cn
