(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) Monthly precipitation distribution based on WRCC station in Brighton
(D) Effective precipitation = 0.7 *(C)/12
(E) Net lake evaporation from exposed water surfaces = (B) - (D)
(F) Total lake evaporation from exposed water surfaces = (E) * Total Exposed Water Surface

(A) Aggregate production percentages
(B) Amount of aggregate production based on percent of annual aggregate production. (Total Material Mined) * Column (A).
(C) Water used for dust control. Monthly amounts where distributed based on estimates from Lafarge
(D) Water Used for washing material. Monthly amounts were distributed based on washing projections from Lafarge, assuming 4% Toss
(E) Column (C) + Column (D).
(F) Total lake evaporation from exposed water surfaces = Net Lake Evap *Total Exposed Water Surface
(G) Column (E) + Column (F).
(H) Total lagged mining depletions which reflect existing real time conditions in stream depletion model.
