Exposed Water Surface 0.4 acres ponds and a drainage ditch
Annual Precipitation 10.3 inches Taken from NOAA Buena Vista Weather Station ID 1071
Gross Annual Evaporation 39 Inches Taken from NOAA Technical Report NWS 33
Notes:
11)Taken from State Engineer's Guidelines for Gravel Pits at elevations above 6500 feet
(2)Taken from NOAA Technical Report NWS 33 and distributed monthly according to Percent of Annual Evaporation(1)
(3)From the NOAA Buena Vista Weather Station ID 1071(1946.2006)
(4)Effective Precipitalon equals 70%of Average Annual Precipitation
15)Gross Evaporation minus Effective Precipitation converted to feet(2)-(4)
(6)Total Evaporative Loss is the product of Net Evaporation 15)and Exposed Water Surface
