Exposed Water Surface= 4.0 acres -Settling ponds,a gravel washing pond,and dewatering trenches
Annual Precipitation= 12.6 inches -Taken from Western Regional Climate Center
Gross Annual Evaporation= 46 inches -Taken from NOAA Technical Report NWS 33
Notes
(1)Taken from State Engineer's Gukkfines for Gravel Pits at elevations below 6500 feet.
(2)Taken from NOAA Technical Report NWS 33 Map 3 and distributed monthly according to Percent of Annual Evaporation(1).
(3) From Western Regional Climate Center Canon City station#51294(1948-2005).
(4)Effective Precipitation equals 70%of Average Annual Precipitation,70%•(3).
(5)Gross Evaporation minus Effective Precipitation converted to units of feet,(2)-(4).
16)Total Evaporative toss is the product of Net Evaporation(5)and Exposed Water Surface and of month Not Froien
