through inlet ditches that divert from the Poudre Valley Canal. As the Poudre Valley Canal <br />travels to its terminus at Cobb Lake, the canal crosses Dry Creek, Boxelder Creek, and Indian <br />Creek. <br />Length: Total length of the Poudre Valley Canal is approximately 30 miles. <br />Capacity: The physical capacity of the Poudre Valley Canal is approximately 350 cfs. <br />Conveyance Efficiency: Unknown <br />Irrigated Area: Poudre Valley Canal is only used to fill reservoirs. Poudre Valley Canal does <br />not directly serve irrigated lands with Larimer Weld Company water. There is a small <br />amount of land between the mouth of the Poudre Canyon and Ted's Place (Hwy 14 and <br />Hwy 287) irrigated under the canal, however, these lands are irrigated with Canon Canal <br />Company water. <br />Return Flow Locations: Return flows from Poudre Valley Canal accrue to the WSSC System <br />to the south and to Dry Creek, Boxelder Creek, Indian Creek, and the Cache la Poudre <br />River. <br />Measurement Device: Diversions through Poudre Valley Canal are measured through a 32 - <br />footrectangular weir equipped with a Stevens recorder. <br />HydroBase Data: Daily diversion data for Poudre Valley Canal is available in HydroBase for <br />the 1950 to 2002 SPDSS study period. Between 1950 and 2002, average annual <br />diversions through Poudre Valley Canal were 16,381 acre-feet per year. <br />Poudre Valley Canal Reservoir System <br />The Poudre Valley Canal Reservoir System includes the following reservoirs: <br />Douglas Reservoir (Structure ID 0303725), <br />Little Windsor Reservoir (aka Windsor Reservoir No. 8) (Structure ID <br />0303727), <br />Annex No. 8 (Structure ID 0303728), <br />Elder Reservoir (Structure ID 0303729), and <br />• Cobb Lake (Structure ID 0303730). <br />All reservoirs under the Poudre Valley Canal Reservoir System are fed through the Poudre <br />Valley Canal. Physical storage under the Poudre Valley Canal Reservoir System is <br />approximately 45,341 acre feet. <br />Douglas Reservoir (Structure ID 0303725) <br />Douglas Reservoir, originally completed in 1901, is filled through the Poudre Valley <br />Canal. Water stored in Douglas Reservoir is released to the Larimer County Canal which <br />is owned by WSSC, for the purpose of exchange. Douglas Reservoir has not been <br />enlarged. In 1990, Douglas Reservoir was emptied for dam safety issues and repair. In <br />2002, Douglas Reservoir did not fill because the water rights were never in priority. <br />Larimer&Weld Memo.doc <br />7 of 20 <br />
