Will a Floating Silt Curtain
Stop Water Flow

I am going to be installing a floating silt curtain in our river, but I am concerned that it will stop the water flow and create stagnant water.

Thank you for your contact! This is valid concern regarding floating silt curtain. You are not the first to wonder about this, especially when the material is impermeable!

Turbidity curtains are not designed to act as water impoundment dams. They aren't expected to stop the flow of a significant volume of water. They are designed to trap sediment, not to halt the movement of water itself. In general, the silt curtains shouldn't be installed across channel flows, which would facilitate the damming. Also, the barrier, when installed, should have at least a 1 foot gap between the bottom of the curtain and the bottom of the river. This allows water to flow underneath and continue moving.
