All of the agricultural land serviced by the Company is privately owned. WATER RIGHTS The company owns no water rights. The water delivered in the ditch is owned by the stockholders and not by the Company. The stockholders own water in the the Larimer and Weld Irrigation Company, the Larimer and Weld Reservoir Company, the Windsor Reservoir and Canal Company, and also CBT water. There are 996.5 shares of stock in the Company which provides the share holder the right have water they own delivered to their headgate. Figure 1 shows the water delivered through the ditch in 1998. The flows shown from May 6 to July 15 are river water and after that date is reservoir water from Douglass Lake, Windsor Reservoir Number 8, No. 8 Annex, Elder Reservoir, and Cobb Lake. The total water delivered to the system at the clockhouse (structure number 7 in Appendix A) for 1998 was 30,000 acre-feet. Approximately one fourth of that is delivered to the West Cut Irrigation Company at the split shown as Number 1 on the map in Appendix A and one fourth of the water is delivered to the Decker Lateral at the end of the Owl Creek system. Based on a total service area of 22,000 acres and a water delivery of approximately 30,000 acre-feet, approximately 1.4 acre-feet of water was delivered for each acre of crop land irrigated under the Owl Creek System. Additional water is delivered to the land that comes from springs, creek flows, storm runoff, and return flows. It is expected that an average of 2.0 to 2.5 acre-feet per acre is actually delivered. NEED FOR THE PROJECT The Owl Creek Supply & Irrigation Company is undertaking this project to repair and/or replace the control structures in the main supply ditch and to provide measuring weirs at each headgate. The control structures in the ditch include drops, checks, and measurement structures that are beyond their useful life. Most of these structures are eroded, the walls have fallen in, and the concrete is spalled and severely deteriorated. Without these structures the measurement of water in the various reaches of the ditch can not be accurately determined which makes it difficult to balance the flow in the ditch with respect to the demands. Presently, the measurement of water at the headgates is done by "feel". There are virtually no usable measuring weirs at the headgates which control discharges to the laterals. Many of the headgates once had rectangular weirs for flow measurement; however, most of these are severely deteriorated and are no longer usable for flow measurement. A typical measuring weir being used is shown on Photograph 5 on the map in Appendix A. The ditch company board has recognized the need to re-establish the control and measurement of Owl Creek Feasibility Page 3
