Table 2 -B
Year Two Operational Water Depletions
United Companies - Colona Gravel Pit SWSP
Notes.
(1) See Table 1 Column (9).
(2) Based on 5,400 gallons of water applied per day, 5 days per week, March through November.
(3) Equivalent to the water that fills the pit and 5,000 tons of matenal removed 6 months out of the year (Oct- March)
(4) Equals Columns (1) + (2) + (3).
(5) Equals the lagged depletions to the Uncompahgre River based on the Glover Analysis
'Lagged depletions assume that the depletion rate from the nver has reached steady state
