Notes:
(A) Net exposed area requiring augmentation. Increases above the current value to account for additional exposure anticipated over the year
(B) Taken from General Guidelines for Substitute Water Supply Plans for Sand and Gravel Pits Submitted to the State Engineer for
elevations below 6500 ft MSL
(C) Gross monthly evaporation = (Gross Annual Evaporation) * (B)
(D) Monthly precipitation from GREELEY UNC, COLORADO (053553) weather station. Period of record is 1967 to 2005
(E) Monthly consumptive use credit = (Historical Consumptive Use Credit) * (D)
(F) Monthly average temperature from GREELEY UNC, COLORADO (053553) weather station. Period of record is 1967 to 2005
(G) Net evaporation = (C) - (E) if the monthly average temperature is greater than freezing. Otherwise, the pond is assumed to be frozen
(H) Evap CU = (A) * (G)/12
