2. System bypass demands and the distribution of those demands are from the 1981 <br />report titled "Preliminary Technical Data report, WyCoalGas Project Water <br />System" prepared by Banner and Associates for Panhandle Eastern Pipe Line. <br />These are also the demands that were utilized by Boyle for the DWAP and include <br />Senior downstream rights and La Prele Irrigation District demands. <br />3. Storable flows are the difference between the inflows and system bypass <br />demands, storable flows are split 25% to PEPL and 75% to the district, and <br />PEPL's storable flows are limited to 5000 acre-feet in any water year. <br />4. Seepage is 3.5 cfs throughout the study period. This assumption was adopted <br />from the DWAP prepared by Boyle. All seepage is charged against the PEPL <br />storage account to the extent that storable flows plus storage are greater than the <br />seepage amount. In simple words, the PEPL account is not allowed to accrue <br />negative amounts when seepage is greater than 25% of the inflows plus storage in <br />PEPL's account. <br />5. Evaporation calculations are simplified using an average surface area of <br />approximately 450 acres and evaporation is prorated 25% to Panhandle Eastern <br />Pipe Line's account and 75% to the remaining storage. This assumption was <br />adopted from the DWAP prepared by Boyle. Similar to seepage, evaporation is <br />not allowed to cause PEPL storage to drop below zero. Evaporation rates for each <br />month are from the 1981 report titled "Preliminary Technical Data report, <br />WyCoalGas Project Water System" prepared by Banner and Associates for <br />Panhandle Eastern Pipe Line. <br />6. Demand on the PEPL account for the Program was structured such that any <br />available storage would be released each water year and releases occur in May- <br />Sept. <br />7. The storage in the PEPL account equals the storage from the previous month plus <br />the storable flow minus seepage minus 25% of the evaporation minus the demand, <br />not to be less than zero. Therefore, demand is limited to the available storage <br />adjusted for seepage and evaporation. <br />8. The Program does not get credit for seepage amounts because seepage is part of <br />the current regime of the river and does not constitute "new" water. <br />9. La Prele deliveries are charged a 10% loss between La Prele Reservoir and <br />Glendo Reservoir. This was adapted from the 1981 report titled "Preliminary <br />Technical Data report, WyCoalGas Project Water System" prepared by Banner <br />and Associates for Panhandle Eastern Pipe Line. <br />Using these assumptions the average annual delivery from the La Prele project for 1947-1994 is <br />2,225 acre-feet per year at the reservoir. <br />\
