Notes:
1) Based on conervahve estimate of inflow rate using linear change in inflow overtime and averaged througtiout the total pit filling
2) Column (1) x (1,440 minutes per day! 325.851 gallons per AF)
3) If (Column (5) from the preulous month I Column (2)) is greater than # of days In the month, than use # of days in month, if not then use (Column (5) from previous month / Column (2))
4) Column (2) x Column (3)
5) Previous month minus Column (4)
61 Lagged to river based on Glover Anatysis with transmissrvity = 50,880 gallons per day per foot, specific yield = 0.20, and distance from centroid of Phase t Pit Area to Colorado River = 906 feet Final 105A of
depletions (months June Through October) redistnbuted amongst first 90% of depletions (months November through May).
7) Based on Colorado River Cali Records from 1987 to 2011 Max call period occured in 2002,
8) Column (6) x (Column (7) / number of days In each month).
