Gross Annual Evaporation = 45 inches per NOAA Technical Report NWS 33
Historical Consumptive Use Credit = 70% of monthly precipitation
Freezing Point of Water = 32 °F
WY 2010 Exposed Water Surface = 17.81 acres within permit area
Notes:
(A) Taken from General Guidelines forSubstitute Water Supply Plans forSand and Gravel Pits Submitted to the State Engineer for
elevations below 6500 ft MSL
(B) Gross monthly evaporation = (Gross Annual Evaporation) * (A)
(C) Monthly precipitation from GREELEY UNC, COLORADO (053553) weather station. Period of record is 1967 to 2005
(D) Monthly consumptive use credit = (Historical Consumptive Use Credit) * (C)
(E) Monthly average temperature from GREELEY UNC, COLORADO (053553) weather station. Period of record is 1967 to 2005
(F) Net evaporation = (B) - (D) if the monthly average temperature is greater than freezing. Otherwise, the pond is assumed to be frozen
(G) Evap CU = (Exposed Water Surface Requiring Augmentation) * (E)/12
