. . CHAPTER I GENERAL INFORMATION . Location Julesburg Irrigation District is located In northeastern Colorado, generally bounded by the Julesburg Reservoir on the west, the South Platte River on the south, the Colorado-Nebraska state line on the north, and the town of Julesburg on the east. The major faclllly of the District is Julesburg Reservoir which straddles the Logan and Sedgwick county line about 20 miles west of Julesburg and 35 miles northeast of Sterting, Colorado, The reservoir Is owned and operated by the District and provides a supplemental irrigation supply to about 19,000 acres within the District. The service area ranges in elevation from 3450 to 3700 feet. The maximum operating water level in the reservoir is 3712, The general location of the District service area and facilities are shown on Figures 1 and 2, . . . District Facilities Julesburg Irrigation District owns and operates several major irrigation facilities, Julesburg Reservoir is retained by four major dam embankments designated Nos, 1 through 4, and a smaller embankment No, 1 A. The maximum earth-fill height is about 65 feet, and the cumulative dam crest lengths are about 8,600 feet. The reservoir capacity is about 28,750 acre-feet at the spillway crest (gage height 28.0) and is about 24,900 acre-feet at the normal maximum operating level (gage height 25.5), The elevation-surface area-capacity relationship is shown on Figure 3, The general location of the reservoir and dams is shown on Figure 1. . . The reservoir outlet works structure is located near the north end of Dam No, 4 (the easternmost dam), The outlet works consists of three horseshoe shaped concrete conduits, 48 Inches wide by 52 Inches high, and 150 feet long, Reservoir sluice gates, located about 90 feet from the inlet structure, are used to control the discharge through each outlet conduit. Maximum discharge capacity through the outlet is about 930 cfs, . . Julesburg Irrigation District derives lis irrigation water supplies from the South Platte River, River water is delivered to the reservoir and District lands through the Harmony Ditch No.1, The diversion structure for the dllch is located about four miles west of Crook. The District also utilizes the Peterson and Settler ditches for direct irrigation, in recent years, very little water has 1 .
