Notes:
(1)Monthly percentages determined in SB89-120 for elevations below 6,500 feet
(2)NOAA Technical Report NWS 33,Evaporation Atlas for the Contiguous 48 United States notes a total annual gross evaporation of 45.0 inches
(3)Gross evaporation=(2)x total exposed surface area which is equal to 28 acres
(4)Based upon the Western Regional Climate Center Station for Brighton,CO(050950)for the time period 1973-2012
(5)Effective precipitation=(4)x 0.7/12
(6)Net lake evaporation=(2)-(5)
(7)Evaporative consumptive use=(6)x total exposed surface area which is equal to 28 acres
(8)Aggregate production provided by Martin Marietta
(9)Water consumed by the washed aggregate is equal to 4%of the total volume of mined material as defined by SB 89-120
(10)Water used for dust control based on Martin Marietta estimates
(11)Operational Consumptive Use=(9)+(10)
(12)Total consumptive use=(7)+(1 I)
(13)Reflects real time lagged depletions due to evaporation,operational uses and past mining activities at the site based on Glover analysis using following parameters
X= 2,700 ft
T= 80,000 gpd/ft
S= 0.2
