Turbidity curtains are an excellent way to minimize the environmental impact your dredging project may have on local wildlife and the health of the nearby water. Sediment and solids picked up by moving around the bottom of the pond will suffocate fish, bury plants, and may contain harmful toxins or hard metals. Turbidity curtains will trap moving sediment, allowing it to settle back at the bottom of the lake.
Placing turbidity curtains or stilts around your project will allow you to control particles and sediment picked up from the bottom of the lake or waterway. Afterwards, you can either allow the sediment to settle with time, or pull out the excess sediment yourself. In most cases, sediment can be removed by using a debris pump to pull it from within the containment area and deposit it in dewatering bags. These bags serve as filters, trapping sediment within and allowing clean water to flow out. These work best in a place where the clean water flows into the original body of water.
