Notes:
[1]Exposed area requiring augmentation allows for augmentation of up to a total of 11.5 acres at Walters/Bokelman Pit.Current exposed area is determined on November 1st of each year
of mining pursuant to Paragraph 36.2 of the decree in Case No.09C W 105.
[2]Total gross evaporation(3.35 feet)is based upon NOAA Technical Report NWS 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: 10.0%
January: 3.0% April: 9.0% July: 15.0% October: 7.0%
[3][1]x[2].
[41 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)
[5]Assumed 70%effective precipitation.[5]is equal to[4]x 70%.
[6][2]-[5]•
(7][1]x[6].
[8]Lagging pattern for the Walters/Bokelman Pit cells 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:981 feet
Distance from center of pit to river:661 feet
[9]The total lagged depletion is equal to the total of[71 x[9].
