Not necessarily. As long as his lake doesn't include sanitary wastewater, oil and grease, meets TSS and turbidity thresholds, doesn't result in a discharge of sediment to the water of the state, isn't a discharge from a sand or gravel mining operation, isn't used in hydrostatic testing, is free of pesticides, the area of disturbance is less than one acre, and is not associated with an automotive repair shop, I can't see where it would be regulated under LAC 33.


I see your point. I agree with you. However, if he cuts a levee and the lake drains fast it will probably bring a lot of sediment in with it. If you could make the lake drain across a field before entering the bayou it would do a good job of catching a lot of sediment. Chances are the pond has a lot of fine sediment that is going to drain with the water if it is in the bottom half of Louisiana.

That is true. He'll probably need to pump at some point anyway, since the bottom of the pond is likely below the bottom of the levee. And no BMPs you'd put up to control sediment are going to hold with 8 acres of water pushing on them.

OP, you trying to drain it dry or just lower the water to get stuff that's growing around the edges? You could rent a 6" pump that flows about 2500 gpm. If your 8 acres averages 5' deep you could suck it dry with one 6" pump flowing 2500gpm in about 70 hours. Would be price of pump rental plus about $500 in diesel.

He should see if anyone who farms would let him borrow an irrigation relift pump and just pump it down before cutting levee
