Notes:
(1)From SEO 05/11/99 for elevations under 6,500 feet
(2)Percent of annual gross evaporation multiplied by 50-inches
(3)Average precipitation from NOAA Climate Station Pueblo Memorial Airport(ID:6740)
(4)col(3)x 70%
(5)col(2)-col(4)
(6)col(5)/12 inches per 1 foot
(7)Based on estimates from operator
(8)col(7)x col(6)
(9)Based on estimates from operator
(10)Water Loss=(Production,col 9)*2000 Ibs/ton*(4%)/((62.4 Ibs/cu ft)/43560 cu ft/acre-foot)
(11)Based on estimates from operator
(12)Conversion to acre-feet.(1 acre-foot=325,851 gallons)
(13)col(10)+col(12)
(14)Total Losses=col(8) +col(13)
(15)Based on 2 ft fill depth(Credit is obtained instantaneously when pit is dewatered.The depletion caused by refilling is lagged to the Arkansas River as if it were an evaporation or operational loss).
(16)Based on Stream Depleton Model
(17)Col(16)+1%transit loss
