Administration <br />Administration of the water rights associated with the Greeley Loveland Irrigation Company <br />involves interaction with the Water District 4 Water Commissioner and the Division 1 Engineer. <br />The Superintendent of the ditch company is more often in contact with these individuals during <br />periods of storage and during periods when direct flow calls have been placed downstream on <br />the Big Thompson River. <br />OPERATIONAL INFORMATION <br />The GLIC system diverts, stores, and delivers water to shareholders. The relatively junior direct <br />flow rights are supplemented primarily with storage in Lake Loveland, Horseshoe Lake, and <br />Boyd Lake. Other agreements and exchanges are also in place to provide additional supplies and <br />flexibility to GLIC and the Louden Ditch system, located above the Barnes Ditch. <br />Although the GLIC system operates the diversion headgates, canals, and storage units owned by <br />three different companies, there is separate share ownership in the Greeley Loveland Irrigation <br />Company, Lake Loveland, and the Seven Lakes Company. Irrigators under the GLIC system <br />have variable amounts of stock ownership in one, two, or all three of the companies. C-BT water <br />is also owned by individual irrigators and can be used within the ditch system. <br />Although there is a great amount of variability in the delivery of water to shareholders within any <br />irrigation ditch system, the order of operations for GLIC's water resources generally follow the <br />pattern enumerated below and described in more detail, following: <br />1) Direct Flow Rights, <br />2) Lake Loveland Releases, <br />3) Horseshoe Lake Releases, <br />4) Boyd Lake Releases, and <br />5) Transbasin Water. <br />The Barnes Ditch water rights and Loveland Greeley Canal water rights (see Table 4) can <br />essentially be used at either ditch for the decreed uses since there are no intervening water rights <br />between the two structures (see Figure 1). The sequence of water rights calls affecting diversion <br />and storage in the Greeley Loveland Irrigation Company and comments regarding operations in a <br />typical year are as follows: <br />Winter <br />• Lake Loveland is the senior filling right under the GLIC system and has Priority 4 of the <br />larger storage rights on the Big Thompson River, after Lone Tree Reservoir under the Home <br />Supply Ditch, Donath Reservoir under the Louden Ditch, and Mariano Reservoir (aka <br />Boedecker Lake) under the Home Supply Ditch. Lake Loveland generally gets between 8 cfs <br />to 20 cfs of the available physical supply during the winter months. <br />• Horseshoe Lake and Boyd Lake have the Priority 5 and Priority 6, respectively, of the larger <br />storage rights on the Big Thompson River. These filling rights are generally satisfied during <br />the spring runoff. During the winter storage season, Lake Loveland and Horseshoe Lake are <br />generally only physically filled to within 3 feet to 4 feet of the top to allow for storm surges. <br />Greeley Loveland Irrigation Company Operating Memorandum.doc 15 of 18 January 5, 2005 <br />
