Notes:
[1)Exposed area requiting augmentation allows for augmentation of up to a total of 53.5 acres at Green/Croissant Pits.
(2]Total gross evaporation(3.35 fact)is based upon NOAA Technical Report NW S 33 and distributed according to SEO Senate Bill 89-120 criteria:
November: 4.0% February: 3.5% May: 12.0% August: 13.5%
December: 3.0% March: 5.5% June: 14.5% September:October: 7.0 %
January: 3.0% April: 9.0% July: 15.0% Octo .0%
(3111]x[2).
[4)Based upon the average of precipitation data at the Waterdale,CO(ID#8839)and Greeley UNC,CO(ID#3553-confirm)NOAA weather stations for the time period 1950-2007(both stations)
[51 Assumed 701/6 effective precipitation.[5]is equal to[41 x 70%.
(6][21-[5]
[7]111 x[61.
[8)Lagging pattern for the Green/Croissant Pits is based upon IDS AWAS Glover Analysis using the following parameters(assuming steady state conditions):
Transmissivity:50,000 gallons/day/foot
Specific Yield:0.2
Aquifer Width:2,179.25 feet
Average distance from edge of pit to river:1,152.5 feet
[9]The total lagged depletion is equal to the total of[71 x 181+[3b]
