Total Exposed Water Surface= 240.9 acres within current permit boundary
Pre-1981 Water Surface= 100.0 acres within current permit boundary;do not require augmentation
Covered by Greeley/Tri-Districts- 125.2 acres within permit boundary;augmented in Greeley/Tri-Districts S W SP
Net Exposed Water Surface= 15.7 acres within current and revised permit boundary
Annual Precipitation= 15.1 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 Genera!Guidelines for Substitute Water Supply Plans for Sand and Grave!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)Net exposed surface area;equals total surface area minus pre-81 surface area and surface arm augmented by Greeley/Tri-Districts.
(0)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)Water used for dust control as specified by Martin Marietta.
(L)Total consumptive use from Cony Pond consists of evaporation from the 15.7 ac surface area and all dust supression pumping.
(M)Total consumptive use from mining area consists of evaporation from 2,500 feet of 5 foot wide dewatering trench and water lost in mining of the material.
(N)Lagging values calculated using following parauete.a:
Distance from stream=1000 ft,Transmissivity=160,000 gpd/ft,Specific Yield=0.2,No-flow Boundary=6500 ft
(0)Lagging values calculated using following parameters:
Distance from stream=1,675 ft,Trsnsmissiviry=160,000 gpd/ft,Specific Yield=0.2,No-flow Boundary=4,675 ft
(P)Column(N)+Column(0).
