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 2012 Gross Exposed Water Surface= 17.81 acres within permit area
Pre-1981 Area= 5.27 acres within permit area
WY 2013 Net Exposed Area= 12.54 acres within permit area(gross area minus pre-1981 area)
Notes:
(A)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
(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=(Net Exposed Area)*(E)/12
