Right now I’m thinking of sloping the pond towards the drain with the construction drain about 3-4’ above the bottom of the pond and 4-6’ out from the face of the dam using a slide gate. Either that or sloping the pond sides towards the drain and digging a 3-4’ deep sump area below the bottom of the drain 4-6’ out from the face of the dam using a slide gate. I was thinking that opening the gate after storms would carry away any sediment that was deposited after the runoff extending the life of the pond. A trash rack of some sort would also be used. I really like Rainman’s idea of the T on a siphon system with 1/2” and 1” holes applied to a drain on a conventional system. Thoughts?
Thanks!
