PHYSICAL INFORMATION <br />Operationally, the minimum flow the inlet canal will divert is 100 cfs. Ditch losses are excessive <br />with a diversion of less than 100 cfs. The total amount diverted at the headgate must be <br />delivered to Riverside Reservoir, as no wasteways exist en route. All System lands are located <br />below the reservoir, and as such, no irrigation deliveries are made directly by the intake canal. <br />Riverside Canal, the outlet from the reservoir, has the ability to release water back to the South <br />Platte River via a ditch located approximately one mile from the outlet of the reservoir. The <br />ditch is approximately one mile in length and is siphoned under the Jackson Lake Inlet to <br />terminate at the river. To date the ditch has not been used for either measured releases or as a <br />wasteway. <br />The System manages its water such that no minimum amount of irrigation water needs to be <br />requested by land owners before releasing water from the reservoir. Irrigation releases are <br />generally made when a group of land owners request water and efficient delivery is feasible. <br />Riverside Canal delivers irrigation to approximately 150 turnouts that serve a total of 22,500 <br />potentially irrigated acres within the System. The turnouts, all of which are measured with <br />weirs, may serve more than one user or farm, and farms may be served by more than one turnout. <br />For management purposes, the canal is divided into four sections to allow for appropriate <br />deliveries and request times. Water users must contact the ditch rider from one to three days in <br />advance, depending on which division the user is in, to request water or change a water request. <br />Once the water has been released, the order cannot be cancelled. Water users cannot request <br />winter releases from the reservoirs. The System employs four ditch riders, one responsible for <br />the inlet canal and the other three responsible for the four divisions downstream of Riverside <br />Reservoir. <br />The first requests for irrigation water typically occur near the beginning of April of each year and <br />end during the middle of September. The System is responsible for the water only to the users' <br />turnouts. The users are generally responsible for opening and closing each turnout gate. <br />Approximately half of the lands in the System are irrigated using sprinkler systems with the <br />remaining half flood irrigated. Use of sprinklers has become more common in the District over <br />the last 10 years. Typical sprinkler operational method is to co-mingle pumped groundwater <br />with surface water deliveries in a private pond on-site to supply the sprinkler. <br />Water entitlement under the System is based on District acreage and/or ownership of Company <br />stock. Initial Company and District water allotments are determined on April 1st of each year. <br />Company allotments of `private rights' are made based on the total useable storage in Riverside <br />Reservoir divided by 2,505 `private rights'. The Company then determines the total allotment of <br />Riverside Reservoir that the District is entitled to. In addition to Riverside Reservoir storage <br />water allotment, the District also owns storage water in Vancil Reservoir. District allotments are <br />based on the sum of the Riverside Reservoir allotment and the total useable amount of storage in <br />Vancil Reservoir divided by approximately 22,500 District acres. Both the Company and <br />District allotments may be changed throughout the irrigation season. Storage carry-over of <br />Riverside Irrigation System.doc Page 4 of 14 <br />
