The estimated total storage in Cobb Lake is 22,300 acre feet. End of month storage <br />records are available for most years in the 1950 to 2002 study period under Structure ID <br />0303730 in HydroBase. End of month storage records for Cobb Lake show that in most <br />years, the reservoir does not fill. However, since the late 1970's Cobb Lake has not been <br />drained completely, at least 2,500 acre-feet of storage has been maintained in the <br />reservoir. <br />3) Little Cache la Poudre System <br />The Little Cache la Poudre System includes the Cache la Poudre Ditch (aka Little Cache la <br />Poudre Ditch) and Larimer Weld Reservoir (aka Terry Lake). The Little Cache la Poudre <br />System lies between the WSSC System to the north and the Larimer and Weld Irrigation Canal <br />to the south. <br />Little Cache la Poudre Ditch (Structure ID 0300915) <br />The Little Cache la Poudre Ditch diverts water from the Cache la Poudre River for irrigation and <br />storage in Terry Lake. The headgate for Little Cache la Poudre Ditch is located on the north side <br />of the Cache la Poudre River approximately 0.5 miles west of the town of Laporte. The Taylor <br />Gill Ditch (Structure ID 0301029) diverts off the Little Cache la Poudre Ditch. Diversions for <br />both structures are measured separately on the Taylor Gill Ditch and downstream on the Little <br />Cache la Poudre Ditch. <br />As the earth lined ditch travels in a general easterly direction through Larimer County to Terry <br />Lake it is intersected by Dry Creek. <br />Ownership: Little Cache la Poudre Ditch is owned by the Cache la Poudre Irrigation Company, <br />and Terry Lake is owned by the Larimer Weld Reservoir Company. Both companies are <br />affiliates of the Larimer and Weld Irrigation Company. <br />Length: Total length of the Little Cache la Poudre Ditch is about 4 miles. <br />Capacity: The physical capacity of the Little Cache la Poudre Ditch is approximately 150 cfs. <br />Conveyance Efficiency: Unknown <br />Irrigated Area: There are approximately 1,033 irrigated acres under the Little Cache la Poudre <br />Ditch. <br />Return Flow Locations: Return flows from the Little Cache la Poudre Ditch accrue to the <br />Larimer Weld Irrigation Canal to the south, Dry Creek, and the Cache la Poudre River. <br />Measurement Device: The measuring device for the Little Cache la Poudre Ditch is a 12 foot <br />Parshall flume equipped with a Stevens recorder. The measuring device is located <br />downstream of the diversion for the Taylor Gill Ditch. <br />Larimer&Weld Memo.doc <br />9 of 20 <br />
