I have a lake every time we get big or multi day rains. The word is connected to the barn which has 10 that goes down into the ground, and there is hardware cloth on the barn side and the east end that is burried. The south side has old chain link fence and is covered with gravel there is a board at the base to connect hardware cloth and the chain link or on the east end of the hardware cloth apron. Unfortunately, between the board and the gravel I have created sort of a dam. I need suggestions for drainage. I thought of putting in like a PVC drain pipe, but it could be chewed through. Ideas?
