sediment control for dredging project

[briandestefano]

I am working on a relatively small, aprozimately 2 acre pond, dredging project in upstate New York; and I am trying to find a way to keep sediment from flowing out of the outlet weir. I've been looking at turbidity curtains but I don't think I can use them across a flowing watercoarse. I know they could use the turbidity curtain if they broke the work up into a couple phases, probably at least 4, but I think that seems a bit excessive for the job.

Does anyone have any ideas how I can keep the dirty water in the pond and allow the clean water to continue flowing out.

Thanks

Use your turbidity curtains on either side of a channel through the pond to the weir. Work outside of the channel will have a chance to settle or filter prior to leaving pond.
