Mechanical dredging is the process of excavating silt or muck from a reservoir. An alternative process of dredging may be preferred for multiple reasons. Booster pumps can enable much further distances, up to miles of pumping, but it may not be economically feasible. Pumping sediment is a very efficient means to transport sediment typically within 2,000 feet of the dredge. Disposal without dewatering is unlikely because of the high volume of water with most dredges. Dewatering techniques can be a settling pond, mechanical screening, belt press, centrifuge, or a geosynthetic dewatering tube. Once the slurry, which is typically 90% water and 10% sediment, reaches the end of the pipeline the water must be separated using a dewatering technique.

Hydraulic dredging is the use of a floating barge with a pump and cutterhead to essentially vacuum the sediment off the lake bed and pump it through a pipeline to a location. RSI can help you navigate through each individual project’s requirements.ĭredging is the removal of silt, muck, or sediment from a body of water. Other dredging permits only allow for removal of silt or sediment down to the original lake bottom (hard-pan). Keep in mind that many of these regulators/operators have rules related to the timing of dredging (related to lake maintenance or fish spawning). Regardless, of the depth of water River Sand is capable of dredging at your lake or dock within the regulations of each reservoir operator. Some reservoirs such as Lake Burton, Lake Seed, and Lake Rabun even have a drawdown period for maintenance along the shoreline, such as dredging. Lake Oconee and Lake Sinclair), or shift with seasonal patterns for flood control (i.e. Water levels on these reservoirs may vary with operation such as pump-storage reservoirs (i.e. Often, the reservoir is controlled by entities such as the US Army Corps of Engineers (USACE), Tennessee Valley Authority (TVA), Southern Company, Georgia Power, Duke Energy, Federal Energy Regulatory Commission (FERC) or other authorities. Fortunately, dredging your reservoir does not require you to lower the water level.
