Lets see, We are at the beginning of the delaware watershed. in fact runoff from 1 side of rt 897 goes to the susquhanna and on my side of the street runoff goes to the delaware. The collection area that feeds the pond is relatively small but there is some street runorff in it. maybe over 1/2 a square mile. not many homes in the mix. maybe 4 or 5.
Its heavy clay soil but the clay is under 18 inches of topsoil. topsoil that stays wet and pretty sticky for days after a rain. it drys rock hard when it dries. The bedrock as far as i know is blue shale and with a mix of limestone. they tell me that drilling wells here is difficult because of voids in the shale , like honeycome.
when we dug the pond it was just about 12 ft before we hit a rock and all clay. 1 spring in the bottom very slow feed from that . the water from that spring was clear. the clay and rock blue gray. my water had a green tint for a long time but is very clear now. have a nice alge bloom going but there is not much vegetation in the pond its self. What is there looks healthy and is growing. Thanks again
