The elevation at the inby base of the bulkhead, where the measurement was taken, is <br />higher than the inside floor elevation at the pump inlet. The difference in floor elevation between <br />the bulkhead and pump inlet level will add some additional storage but the volume is small. <br />The water storage volume, based on the 5'-1"height of the bulkhead is 48,000 gallons, or 0.148 <br />acre-feet. This is about 15,000 gallons more than my December 18th eari,nnr~ of storage to the <br />high wafer line of 4.15 feet. <br />Sincere) <br />I ~~ <br />Richard Fox, P.E. <br />Consultant to COM, tnc <br />ec: Gwen Fraser <br />Tim Hartley <br />Richard Fanyo <br />
