Erosion occurs in ponds as a result of wave action, water currents from aerators, inadvertent damage from vehicles or other equipment, and rain impacting on bottoms, dams, and embankments of empty ponds. Soil particles suspended by erosion increase total suspended solid concentrations in pond waters and effluents, and clay particles increase turbidity. Sediment removed from ponds and improperly disposed of can erode and cause contamination of surface water with suspended solids.
Prevention of Erosion
- Close drains as soon as the maintenance or other activities for which the pond was drained are completed.
- Prevent if possible and repair immediately inadvertent damage caused by vehicles or other equipment.
- Stationary mechanical aerators should be installed so that water currents caused by these devices do not cause erosion of pond earthwork.
- Tractor-powered emergency aerators should be positioned to avoid erosion.
- Sediment should be used where possible to repair pond earthwork. If sediment is removed from ponds, it should be stabilized to prevent erosion.
- Earthen berms, riprap, or vegetation can be used to minimize the effects of erosion from waves.
