PHYSICAL INFORMATION <br />The GLIC system operates two main ditches and canals (Barnes Ditch and Loveland Greeley <br />Canal), three primary reservoirs (Lake Loveland, Horseshoe Lake, and Boyd Lake), and six <br />secondary reservoirs. The GLIC system consists of two river headgates, over 200 miles of canals <br />and filler ditches, over 70,000 acre-feet (ac-ft) of storage capacity, associated inlet and outlet <br />structures, and other infrastructure integral to the delivery of water throughout the system. <br />GLIC owns and operates the Barnes Ditch, Loveland Greeley Canal, Boyd Lake, Equalizer Lake <br />and Houts Reservoir. GLIC also operates Lake Loveland for the benefit of Lake Loveland <br />contract right holders. The Seven Lakes Company owns, and GLIC operates Horseshoe Lake <br />(Lake Nos. 1 and 2), Westerdoll Lake (Lake No. 3), Heinricy Lake (Lake No. 4), Upper Hoffman <br />Lake (Lake No. 6), and Lower Hoffman Lake (Lake No. 7). The Seven Lakes Company <br />originally owned Silver Lake aka Cemetery Lake (Lake No. 5), which was transferred to the <br />Louden Ditch Company in the early-1900s. Three separate lateral ditch companies on the lower <br />portion of the Loveland Greeley Canal own and operate the Oklahoma Ditch and Oklahoma <br />Reservoir; the Boomerang Ditch, North Boomerang Ditch Extension, and West Boomerang <br />Ditch Extension; and the Grapevine Ditch. GLIC delivers water to these entities from the main <br />canal, after which deliveries are conveyed to shareholders by the three lateral ditch companies. <br />The layout of the system, connections amongst the elements that make up the GLIC <br />infrastructure, and associated background information are discussed below in a generally <br />upstream to downstream order. The storage units and ditches described below are all located in <br />Water District 4 in Larimer County. The lower portions of the Loveland Greeley Canal are <br />located in Water District 4 in Weld County. <br />1) Barnes Ditch (Structure ID 0400501) <br />The Barnes Ditch headgate consists of three 10-foot radial gates on the north side of the Big <br />Thompson River, located as shown on Figure 1. The Barnes Ditch and Chubbuck Ditch systems <br />were purchased by the newly-formed Greeley Loveland and Land Company in the 1870s, at <br />which time the ditch headgates were enlarged, the ditch capacities were enlarged, and the <br />Chubbuck Ditch was extended east from its terminus near Interstate 25 toward Greeley. After <br />Lake Loveland was acquired, the Barnes Ditch was renamed the Big Barnes Ditch from the river <br />to the Lake Loveland inlet. The ditch below this point extended to Westerdoll Lake and was <br />renamed the Little Barnes Ditch. The Little Barnes Ditch was abandoned by the City of Loveland <br />in the 1980s from Eisenhower Boulevard to Westerdoll Lake as lands historically irrigated by the <br />Little Barnes Ditch were incorporated into the City of Loveland. <br />The Barnes Ditch is an earthen canal over its entire length. Although the ditch was concrete-lined <br />in the early-1900s, the remnants of this effort provide little, to no, savings to ditch losses. No <br />estimates of conveyance losses were available from the Barnes Ditch, specifically. Overall <br />system losses (storage and ditches) are estimated at 22 percent. The Big Barnes Ditch headgate is <br />located on the north side of the Big Thompson River. The ditch travels in a generally easterly <br />direction towards Lake Loveland. The ditch is used to fill Lake Loveland, Horseshoe Lake, and <br />Boyd Lake. The Little Barnes Ditch generally travels from Lake Loveland in an easterly <br />Greeley Loveland Irrigation Company Operating Memorandum.doc 4 of 18 January 5, 2005 <br />
