building large natural pond
I have a hill side that has water draining through the soil. It is a clay and sandy/gravel mix.Three years ago while planting trees I discovered water seeping into the hole I dug. I built a 4 inch drill and hand drilled down to 11 feet until I hit a rock. Several other holes stopped at close to the same depth. The hole has never dried up but has filled in with soil so that it is only about 6 ft deep now and has widened itself. I can empty the hole with a coffee can but it fills back up. During the driest month it produced less water. On Jan 4 I drew 30 cans out and it was filling up as I drew. It seems that have a shallow spring there. Has anyone built a pond with these conditions?Will a dug out pond produce more springs?How would I prevent the water from draining out further down hill? This is during zone3/4 wisconsin winter.I would appreciaate some answers if possible.
