PHYSICAL INFORMATION <br />Cameron Pass Ditch originates in Water Division <br />6 District 47 and terminates in Water Division 1 <br />District 3 in Larimer County. <br />Construction of Cameron Pass Ditch began in <br />1892. Since first ditch water in 1913, the <br />diversion has been in continuous operation. The <br />ditch was historically used to provide irrigation <br />water to irrigators in the Cache la Poudre basin. <br />Cameron Pass Ditch collection system intercepts <br />overland flow from the surrounding watershed <br />and transports the water from the North Platte <br />River basin to the South Platte River basin. <br />Length: Approximately one mile. <br />Capacity: At least 21 cfs. (12 cfs was the maximum daily diversion recorded on June 30, 1973) <br />Diversion Measurement Device: <br />DWR WDID: 4704602 <br />USGS ID: CAPDCPCO -Cameron Pass Ditch near Cameron Pass <br />Datum: 10,300 feet above sea level NGVD29 <br />Outlet Ditch: 2 foot Parshall flume equipped with a F 1 recorder. Cameron Pass Ditch is <br />not equipped with a satellite linked monitoring system. The measurement device is <br />located at the terminus of the ditch, before water is released into Joe Wright Creek, on the <br />North side of Highway 14, near the headgate for Michigan Ditch. <br />Conveyance Efficiency: The ditch was originally earth-lined. It is unknown if portions of the <br />ditch have ever been lined or if any significant improvements or modifications have been <br />made to Cameron Pass Ditch. Water rights for Cameron Pass Ditch indicate a volumetric <br />enlargement of the ditch in a second decree. It is unknown if any ditch modification were <br />performed in accordance with the decreed volumetric ditch enlargement. <br />HydroBase Data: Diversions are reported as continuously monitored streamflow records and <br />administrative records by Colorado Division of Water Resources (DWR). Continuously <br />monitored streamflow records are available for Station CAPDCPCO for water years 1931 <br />through 2002. Administrative diversion records are available for Structure 4704602 for <br />water year 1987 through 2002. Both continuously monitored streamflow records and <br />administrative diversion records are available on a daily and monthly basis through <br />Colorado DWR HydroBase.
