-12- <br />. Total storage is the amount of water that the sedimentation <br />ponds can store in dead storage and in active storage and <br />is 184.8 acre-feet. The active storage, 117.9 acre-feet, <br />will be detained only long enough to meet water quality <br />standards, Less than 24 hours. The remaining 66.9 acre-feet <br />is dead storage and cannot be released from the sedimenta- <br />tion ponds to the stream system. <br />Table 3 shows the projected monthly inflow of water to dead <br />storage. The sedimentation ponds are expected to fill <br />during the snowmelt season of April and May each year. For <br />planning purposes, it has been assumed that 33.45 acre-feet <br />will flow into dead storage in April, 33.45 acre-feet in <br />May. Once the dead storage in the sedimentation ponds is <br />filled, with water or sediment, it cannot be released to <br />the stream system. <br />• Flow of water into the open mine pit from shallow aquifers <br />is expected to occur as mining proceeds across the <br />property. It has been estimated that inflow to the pits <br />will occur at a maximum rate of 35 of/yr. The New Pit well <br />• water right, permitted for 35 acre-feet annually, Water <br />Court Case No. 80CW78, will account for this inflow. This <br />right will be used to pump water from the actively mined <br />portion of the pit and put to use or pumped back to the <br />stream system as it accumulates in the mine. <br />• <br />~(~ Leonard Rice Consulting Water EnUmBers lnc <br />
