Hydrologic
• Pond FW-1 provides for water storage.
Water can also be stored in Sediment Ponds
MB-1, MB-2, and MB-3 under a separate
decree. Storage is usually limited to the
maximum sediment level elevation. Trans-
fer to FW-1 is possible as outlined in the M
& R Plan. Average withdrawals are not
expected to exceed 400,000 gallons per day
Morsiroring Ac[ivifiet
(gpd). Flow may fluctuate depending on
requirements associated with varying pro-
duction levels. During 1993, the average
withdrawal was 159,276 gpd for 250 work-
ing days. This increase in usage can be
attributed to more consistent operation of the
longwall and the resultant increase in pro-
duction.
