Douglas Reservoir Total Storage: 8,834 acre-feet <br />Douglas Reservoir Active Storage: 7,888 acre-feet <br />Douglas Reservoir Dead Storage: 946 acre-feet <br />End of month storage records are available through HydroBase for most of the 1950 to <br />2002 SPDSS study period. End-of--month storage records presented in HydroBase <br />include the 946 acre-feet associated with dead storage in Douglas Reservoir. Reservoir <br />gage height and associated cumulative capacity information for Douglas Reservoir is <br />available from George Varra, Water District 3 Water Commissioner. <br />Little Windsor Reservoir (Structure ID 0303727), Annex No. 8 (Structure ID 0303728), <br />and Elder Reservoir (Structure ID 0303729) <br />Little Windsor Reservoir is physically separate from Annex No. 8 and Elder Reservoir, <br />two nearby reservoirs also owned by Windsor Reservoir and Canal Company. However, <br />operation of these three reservoirs is coordinated through the design of the system. Water <br />diverted from Poudre Valley Canal is first delivered to Little Windsor Reservoir. Little <br />Windsor Reservoir feeds Annex No. 8. In 2003, Elder Reservoir was rehabilitated such <br />that it can be filled after Little Windsor Reservoir and Annex No. 8, through releases <br />from Annex No. 8. Water stored in Little Windsor Reservoir and the associated <br />reservoirs is released to Larimer County Canal for exchange purposes or to Larimer Weld <br />Irrigation Canal for irrigation. <br />The total storage for Reservoir No. 8, Annex No. 8, and Elder Reservoir is 14,207 acre- <br />feet. This total storage amount is broken down by reservoir as follows: <br />Reservoir No. 8 Total Storage: 9,884 acre-feet <br />Annex No. 8 Total Storage: 3,657 acre-feet <br />Elder Reservoir Total Storage: 666 acre-feet <br />The active storage and dead storage component for each of the three reservoirs is <br />unknown. <br />End of month storage records are available for Reservoir No. 8 and Annex No. 8 for the <br />1950 through 2002 study period in HydroBase under Structure ID 0303727 and 020728, <br />respectively. End of month storage records are not available for Elder Reservoir through <br />HydroBase. <br />Cobb Lake (Structure ID 0303730) <br />Cobb Lake is located at the end of the Poudre Valley Canal. The outlet of Cobb Lake <br />feeds into Larimer County Canal, owned by WSSC. Due to the location of Cobb Lake <br />relative to the Larimer Weld System, and as a result of losses associated with transporting <br />water down the canal to Cobb Lake, the importance of Cobb Lake to the operation of the <br />Larimer Weld System is declining. However, due to various decreed exchanges, the <br />storage of water associated with Cobb Lake within the System is still possible. <br />Larimer&Weld Memo.doc <br />8 of 20 <br />
