Study Area and Existing Facilities Description <br /> <br />The Greeley and Loveland Irrigation system is located in the vicinity of Loveland as shown in <br />Figure III-!. The system is supplied by two diversions located on the Big Thompson River: 1) Big <br />Barnes diversion and 2) Greeley and Loveland diversion. The first diversion is the Big Bames ditch, <br />which diverts water to Lake Loveland. The water is then regulated by several reservoirs before it can be <br />released into the lower reaches of the Greeley and Loveland Canal. The second diversion is the Greeley <br />and Loveland Canal, which diverts water to Equalizer Reservoir. Equalizer Reservoir is the last <br />reservoir on the system before water is delivered to the shareholders to the east including the City of <br />Greeley. The City of Greeley is located approximately 30 rniles to the east of Equalizer Reservoir. <br /> <br />The Greeley and Loveland Company owns and controls Lake Loveland, Boyd Lake, and the <br />Equalizer and Houts Lake Reservoirs. The Seven Lakes Reservoir Company owns and controls five <br />reservoirs; Horseshoe Lake, Westerdoll Lake, Heinricy Lake, and Upper and Lower Hoffman Lakes. <br />The interchange facilities of the systern to exchange water between the two companies has been <br />developed over the years to afford greater use of the water. <br /> <br />There are two dam that irnpounds Horseshoe Reservoir; Dam No. I to the south, and Dam No.2 <br />to the east. Horseshoe Dam No. 2 is located between Horseshoe and Boyd Reservoirs. The outlet <br />Works is jointly owned and operated by the Greeley and Loveland Irrigation Company and the Seven <br />Lakes Reservoir Company. The 48-inch corrugated metal outlet pipe downstream of the Horseshoe gate <br />chamber was sleeved with a 42-inch steel pipe in 1985. The inlet pipe between the intake and gate <br />chamber is the old 48-inch CMP. The condition of the intake pipe- is questionable based on the <br />condition of the other related CMP. The gate chamber consists of a 72-inch CMP with a concrete <br />foundation. The failure of the gate has compromised the structural integrity of the 72-inch CMP gate <br />chamber. <br /> <br />In summary, there are three deficiencies associated with Horseshoe Dam No.2 outlet works. The <br />deficiencies include the following: <br /> <br />Horseshoe Dam NO.2 Outlet Works Study <br /> <br />12 <br /> <br />BOYLE <br />
