Lake Cities, and other Clear Creek water users th at determine operations of the reservoir. The <br />general current operating procedures of the reser voir and associated ditch systems are discussed <br />below along with information related to how the Standley Lake system is integrated with the <br />municipal water supplies of the Standley Lake Ci ties. Additional information regarding Standley <br />Lake and Clear Creek operations can be found in the SPDSS Task 3 Memorandum – Notes from <br />Water District 7 Meeting . <br />FRICO is a mutual ditch company and allocates water to its share holde rs based on a pro-rata <br />portion of the total amount of water diverted in to the system, including releases from storage, <br />regardless of the location of each share holder within the Standley Lake Division. Reservoir <br />losses and evaporation and ditch lo sses are subtracted from the water in storage to determine the <br />headgate yield allocated per share. At the beginni ng of the irrigation seaso n, the first allocation is <br />made with a conservation pool to allow for variab le reservoir and ditch losses. As the amount of <br />water remaining in storage or from direct divers ions allows, additional allocations may be made <br />as the irrigation season progresses. The long-term average yield is approximately 5.4 ac-ft per <br />share. <br />Major Agreements <br />The major agreements that affect Standl ey Lake operations are discussed below: <br />Four-Way Agreement <br />The Four-Way Agreement, dated June 27, 1979, is an agreement between FRICO, Westminster, <br />Thornton, and Northglenn (Standley Lake Cities) that describes the operations and maintenance <br />of the FRICO storage space within Standley Lake Reservoir. The fraction of the FRICO storage <br />space allocated to each party is determined by di viding the number of shares held by each party <br />by the total number of FRICO shares. The agreemen t also describes the process of storage space <br />sharing between parties. If one entity stores in excess of its own storag e entitlement and another <br />entity has storage space, then a paper exchange is used to “bookover” water from the account <br />that is in excess to the account that can legally fill. If the rese rvoir fills and spills, the booked <br />over water is subject to getting bumped out. <br />Cosmic Agreement <br />The Croke Canal headgate is located downstrea m of the pre-1988 Golden and Coors effluent <br />return point. This caused Clear Creek water divert ed at the Croke Canal h eadgate to be of poor <br />quality during winter months. During the la te 1970s and early 1980s, Coors and Golden <br />considered diverting additional water from Clear Creek that belonged to downstream water users <br />Westminster and Thornton and replacing it with treated effluent. Westminster and Thornton <br />fought this concept through a number of fo rums including the Water Quality Control <br />Commission and the Water Court. The parties ne gotiated an innovative settlement that involved <br />the joint funding of a solution that gave Coors and Golden additional water supplies from Clear <br />Creek, while preserving the quality of the Standley Lake water supply. The agreement <br />committed all parties to operate water rights to avoid the introduction of Coors and Golden <br />effluent into Standley Lake. This water quality goal is achieved without a significant loss of <br />water yield for any party to this agreement and wi thout injury to other wa ter users not a party to <br />this agreement. The parties also put to rest ove r 30 separate legal disp utes that had arisen <br />between them over this issue. The agreement was signed in 1988 and has been considered <br />19 of 24 <br />
