The Honda pump I have will pump 150 gpm......sounds like a lot until you do the math. It takes 3 hours of pumping to raise my water level 1". Now considering it costs about 3.65 an hour to pump, that one inch of water costs me $10.95.......plus the cost of the pump and hoses. So, if I had an unlimited water source, it would cost me $131 to raise my water level one foot. Not bad. Just don't have the water. We have had very few rain storms that have allowed me to pump. And, at most I have been able to pump has been about 2 hours before the creek level dropped.

Beating my head against the wall.
