You say you have a "groundwater" pond. To me that means the water level reflects what the water table surrounding the pond is. Both Esshup and I have groundwater ponds and they both fluctuate according to the weather. Right now mine is 11' deep but I'll bet by mid to late july it will be in the 8-9' range. Do some checking to make sure you're not going to do expensive work with not so good results. It is possible you may have a larger "pond" but a smaller and more shallow body of water. Good luck and hope yo can improve your pond. Bob-O
