Total Exposed Water Surface = 3.05 acres within current permit boundary
Annual Precipitation = 1 15.5 inches -Based on Western Regional Climate Center Fort Collins, CO Station (050035)
Gross Annual Evaporation 1 38 1 inches - Taken from NOAA Technical Report NWS 33
Notes:
(A) Taken from General Guidelines for Substitute Water Suppli' 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
(G) Total lake evaporation from exposed water surfaces = (E) * (F).
(H) Crushed aggregate amounts provided by Martin Marietta.
(1) Washed aggregate amounts provided by Martin Marietta
(J) Water retained in product equals 4% of total weight of washed aggregate produced and 2% of total weight of crushed aggregate produced
(K) Equal to (F) + (J)
(L) Lagging calculations were based on the following parameters:
Distance from stream = 1,600 ft, Transmissivity = 160,000 gpd/ft, Specific Yield = 0.2, No -flow Boundary = 2900 ft
Lagged depletions at the site include historical mining depletions and current and past evaporative depletions.
