Inches -Taken from NOAA Technical Report NWS 33
Notes:
(A) Taken from General Guidelines for Substitute Water Supply Plans for Sand and Gravel Pits Submitted to The State Engineer.
(B) Gross lake evaporation = (A) '(Gross Annual Evaporation / 12)
(C) Estimated using annual precipitation and monthly distribution of precipitation from the Western Regional Climate Center - Fort Collins, CO (050035).
(D) Effective precipitation = 0.7 *(C) /12.
(E) Net lake evaporation from exposed water surfaces = (B) - (D), there is no evaporation December - February due to below - freezing average monthly temperatures.
(F) Net exposed surface area; equals gross surface area minus pre -8I surface area.
(G) Total lake evaporation from exposed water surfaces = (E) * (F).
(H) Water used for dust control as specified by Martin Marietta Materials.
(I) Column (E) + Column (F)
(J) Lagging values calculated using following parameters:
Distance from stream = 1000 ft, Transmissivity = 160,000 gpd/ft, Specific Yield = 0.2, No -flow Boundary = 6500 ft
