; ~~-~~ :""-;., ',' ....;~ livestock along the entire canal. Construction, operation and main- tenance access to the diversion dam would be over an existing road that would be upgraded. Construction access to the canal would be from existing roads. An operation and maintenance access road would be constructed along the canal bank. Some project land would be served directly from the canal by means of the Southern Ute Pumping Plant, which would pump water from the canal into an elevated tank that would pressurize an irrigation lateral system serving project land immediately north of the State line, The pumping plant would be similar to those to be constructed along the Dry Side Canal, About 4.6 miles of buried laterals would convey water for the irrigation of 988 acres. Table A-5 provides additional inform- ation for the pumping plant.

The dam would be located in New Mexico on Cinder Gulch, an intermittent tributary 2 miles east of the La Plata River. Figures A-6 and A-7 show the site and an artist's concept of the reservoir, It would be a rolled, earthfill structure with a height of 170 feet, a crest length of 2,900 feet, and a material volume of 2,640,000 cubic yards. An outlet works with a 730-cfs discharge capacity would be constructed near the left abutment ,The dam would not have a spillway because the reservoir's surcharge capacity of 3,300 acre-feet, in conjunction with the outlet works, would protect the dam against the inflow design flood. ~ j. ~ '~f- The reservoir, with a capacity of 70,000 acre-feet, would extend about 2.6 miles up Cinder Gulch and would receive water from the So~thern Ute Inlet Canal. The reservoir's active capacity of 40,000 acre-feet would be released through the outlet works. The dead and inactive capacity of about 30,000 acre-feet, which would form the reservoir's minimum pool and would not be drawn upon under normal circum- stances, would benefit recreation and fishing use at the reservoir, Table A-6 provides additional data on the reservoir, ~l A-18
