Ground Water Rights <br />The City does not use any ground water supplies in its potable system. <br />Transbasin Water <br />The City of Fort Collins is within the boundaries of the Northern Colorado Water Conservancy <br />District (NCWCD). As such, water made available through the Colorado-Big Thompson (C-BT) <br />Project is used within the City's service area. The City began deliveries associated with its <br />original ownership of 6,052 C-BT units in the 1950s. The C-BT ownership has increased over <br />time to a current holding of 18,855 units, mainly as a consequence of raw water dedications. <br />Since the mid-1980s, Fort Collins has also had use of 4,200 ac-ft/yr of Windy Gap water from <br />Horsetooth Reservoir in exchange for the City's provision of 4,200 ac-ft/yr of reusable effluent <br />(the Reuse Plan) to the Platte River Power Authority (PRPA, see Operational Information section <br />below). <br />Pending Water Rights Cases <br />The City does not have any large water rights cases pending in the Water Division 1 water court <br />at the present time. It is involved, however, in several smaller cases that are pending in the court. <br />OPERATIONAL INFORMATION <br />Water Demands <br />The City's potable demand was approximately 31,000 ac-ft/yr in 2001, corresponding with a <br />population of about 121,000 within the Fort Collins service area. After subtracting out large <br />contractual uses of about 4,000 ac-ft, this demand level equates to approximately 200 gallons per <br />capita per day (gpcd). During 2003 and 2004, treated water demands were reduced to about <br />25,000 ac-ft per year, due to drought awareness, restrictions, an increasing block rate structure, <br />and wetter conditions. The city population includes about 25,000 Colorado State University <br />students, of which an estimated 75% live in off-campus residences. Current planning efforts <br />anticipate future unit water use to be about 185 gpcd, as a result of the City's continued demand <br />management efforts. The City's current demand level is less than the approximately 254 gpcd <br />South Platte River basin Northern area demand reported in the Statewide Water Supply <br />Initiative. The currently anticipated water demand level for the year 2040 is about 43,500 ac-ft/yr <br />(including about 8,500 ac-ft of large contractual demands) for a population of about 165,000. <br />The City also has non-potable contractual obligations of about 4,000 ac-ft per year and uses from <br />3,000 to 4,000 ac-ft for raw water irrigation. The City has historically irrigated public parks and <br />green belt areas with its ditch shares for those areas located along and near the ditches that run <br />through the City. These non-potable supplies are currently used to irrigate about 1,500 acres. <br />This land can also be supplied by potable water supplies if insufficient ditch diversions are <br />available. The City anticipates the future demand will include the current level of contractual <br />obligations and that non-potable irrigation use will remain at about 10 to 13 percent of the <br />potable demand. <br />City of Fort Collins Operating Memorandum.doc 15 of 20 January 5, 2005 <br />
