Hello,i have a 1/3 acre pond in upstate NY by Cooperstown NY.I believe there is a seasonal spring that feeds one spot in the bottom of the pond at one end.The seasonal spring comes from up above the pond and down a gradual slope under ground to the pond.I see shail in the bottom of the pond 5 foot deep side that is wet when the pond is down The other end of the pond is 10 feet deep when full and goes to 5 feet deep when the pond is low. I lose 1 inch of water per day starting in May.Being full in March and April. I am going to try to dam off the under ground spring by digging down and making a hole,fill it wth gravel #2 and than put a pipe in the top of the hole to feed the top of the pond. I also will have to put clay back to seal where the shail is now exposed in the pond. I read about DB110 and DB200 and would like to buy that also to out in my pond at the shail.Any body try that stuff before??? Thanks john
