Exposed Water Surface = 4.0 acres -3 settling ponds,a gravel washing pond,and dewatering trenche
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 Guidelines 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 H51294(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).
(6)Total Evaporative Loss is the product of Net Evaporation(5)and Exposed Water Surface and%of month Not Frozen
