Gross Exposed Water Surface= 0.00 acres within current permit boundary
Annual Precipitation= 15.5 inches -Based on Western Regional Climate Center Fort Collins,CO Station(050035)
Gross Annual Evaporation= 38 inches -Taken from NOAA Technical Report NWS 33
Notes:
(A)Based upon SEO General Guidelines for Substitute Water Supply Plans for Sand and Gravel Pits.
(B)Gross lake evaporation=(A)*(Gross Annual Evaporation/12).
(C)Estimated using annual precipitation and average 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).Based on information from the Western Regional Climate Center Station for Fort Collins,CO(053005)over a study
period of 1893-2012,there is no evaporation December-February due to below-freezing average monthly temperatures.
(F)All cells at the Overland Ponds Site are lined and therefore,there is no exposed water surface area.
(G)Total lake evaporation from exposed water surfaces=(E)•(F).
(H)Crushed aggregate amounts provided by Martin Marietta.
(I)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)Dust control water volumes provided by Martin Marietta.
(L)Equals(J)+(K).
(M)Equals(G)+(L).
(G)Lagging calculations were based on the following parameters:
Distance from stream=2,000 ft,Transmissivity=160,000 gpd/ft,Specific Yield=0.2,No-flow Boundary=3,000 ft
