At this time, the Recharge Ponds 1, 2, 3 and 5 along with the slough have been constructed. <br /> • None of the other Recharge Facilities have been surveyed. Therefore, the maximum number of <br /> surface acres associated with future Recharge Facilities and the number of surface acres as a <br /> function of the depth of water in each future Recharge Facility is not defined. Prior to the <br /> diversion of water into any Recharge Facility that has not been constructed as of the date of this <br /> decree, CDOW shall provide the Water Commissioner, and all objectors, a copy of a diagram <br /> depicting the location of the Recharge Facility, an estimate of the maximum number of surface <br /> acres of the Recharge Facility, an area capacity table for the Recharge Facility and the <br /> methodology by which this information was developed. <br /> 8.3 Evaporation Calculation. <br /> The amount of water lost to evaporation shall be determined by multiplying the exposed water <br /> surface area of each Recharge Facility by the rate of net evaporation for the days of exposed <br /> water surface. CDOW will use real time net evaporation data. If data is unavailable, CDOW will <br /> use the average net values, which are acre feet per acre of exposed surface area, in the following <br /> table. <br /> Month Jan Feb Mar Apr May Jun July Aug Sep Oct Nov Dec <br /> AF /A 0.095 0.11 0.155 0.265 0.29 0.415 0.455 0.435 0.33 0.225 0.125 0.10 <br /> Real time net evaporation will be determined as follows, or by an alternative procedure that has <br /> • received prior approval by the State Engineer. Site - specific data obtained from the Crook <br /> weather station maintained by NCWCD will be used in the calculations. Gross pan evaporation <br /> will be computed from published monthly data on the NCWCD web site by multiplying standard <br /> alfalfa reference ETr by 1.2 (FAO Irrigation and Drainage Paper #24/56 - 1977/1998). Gross pan <br /> evaporation will be multiplied by 0.7 to obtain gross Recharge Facility evaporation. Net <br /> Recharge Facility evaporation in inches will be computed as gross pond evaporation minus <br /> effective precipitation, where effective precipitation is total precipitation multiplied by 0.7. <br /> • <br /> 20 !Page <br />
