rangersedge, i am not sure...i initially thought your spring was at the deepest spot...which at 25 feet would be a lot of pressure. or is it seeping out at the level of near full stage (less pressure?) also, is it in a flat area, or is it on the edge of a hill? if it is not in the deepest part, i would think you could give it a shot and see what happens. if the water drops down below it, then cover it up later with clay/bentonite or whatever. i was really lucky to have a strong spring...there are 2 other small springs around the property that are dry during summer...if i had built the dam past those, probably would have the dilemma you are facing...tough decision...i'd say totally depends on where in the depth your spring is located and flat/or hillside. mark
