Notes:
[1]Exposed area requiring augmentation allows for augmentation of up to a total of 53.5 acres at Green/Croissant Pits.Current exposed area is determined on November 1st of each year of mining pursuant to Paragraph 36.2
of the decree in Case No.09CW 105. (Total exposed area allowed is 65 acres between Green/Croissant and Bokehnan/Walters)
[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: 7.01/o

[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)
[5]Assumed 70%effective precipitation.[5]is equal to[4]x 70%.

[81 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 center of pit to river: 1,152.5 feet
[9]The total lagged depletion is equal to the total of[7]x[8]+[3b]
