Additional information concerning individual ownership of Iliff Irrigation District acre- <br />rights is provided in Attachment 1. <br />Morgan Prewitt Reservoir Company: Represents approximately 261 shares <br />outstanding, and 19.4% of the total ownership in Prewitt Reservoir. Water from Prewitt <br />is not subject to limitations on locations of use within any irrigation district. Users <br />typically receive 16 acre-feet per share and are not assessed delivery losses. Additional <br />information concerning individual ownership of Morgan Prewitt Reservoir Company <br />shares is provided in Attachment 1. <br />Transbasin Rights <br />Prewitt Reservoir is within the boundaries of the Northern Colorado Water Conservancy District. <br />As such, water made available through the Colorado-Big Thompson (C-BT) Project may be used <br />on lands utilizing water from Prewitt Reservoir. Currently no C-BT water is delivered to the <br />reservoir. <br />Administration <br />Administration of the water rights associated with Prewitt Inlet Canal and Prewitt Reservoir <br />involve interaction with both Water Districts 1 and 64. In addition to contact with Water <br />Commissioners in both Districts, the Manager is in contact with the Division Engineer on a <br />regular basis to determine upstream conditions that may affect the reservoir's operation. <br />OPERATIONAL INFORMATION <br />Prewitt Reservoir typically begins to fill each year under its senior water right in October. If <br />there is significant carry-over storage, Prewitt Reservoir can delay start of storage. North <br />Sterling Reservoir's senior storage right is senior to Prewitt Reservoir's storage right, therefore <br />Prewitt Reservoir will begin to divert and store any in-priority water that is not diverted by North <br />Sterling. Prewitt Reservoir will store through winter and spring months under its senior water <br />right up to 28,600 acre-feet (current restricted storage level). Prewitt's junior storage right is <br />used for refill purposes. Any storage water remaining from the previous year is charged against <br />the senior storage right. <br />Where to find more information <br />^ The Water District 1 Meeting Notes and Water District 64 Meeting Notes prepared for <br />SPDSS Task 3 -Identify Key Diversion Structures contain additional information on <br />ditch and reservoir operations within these water districts. <br />^ The Irrigated Acreage Assessment GIS Coverage prepared for SPDSS displays the <br />boundary of the South Platte Ditch service area, as well as other service area boundries <br />utilizing Prewitt Reservoir water.
