![]() ![]() While planning projects, this is often a question asked that is difficult but necessary. Dredging is typically more expensive when compared to standard grading or dirt moving because of the equipment and nature of working on/within/near water and the separation of water from the sediment. However, to give you an idea we have dredged lakes from $5 per cubic yard to $500 per cubic yard. This is why it is so difficult to even give a range of cost for dredging. fencing) grading and clearing dewatering, reclamation of the access, disposal, or dewatering area(s) and permitting are all cost that must be considered for each dredging project. Mobilization and demobilization of equipment erosion control measures safety measures (i.e. Once it is determined how much volume of sediment needs to be removed the unit cost per cubic yard can be used to multiply. Most dredging projects involve a cost per cubic yard as a commonly accepted unit of measurement. Typically, the primary question to answer revolves around the amount of sediment to be removed. Some of the factors include access, sediment type, sediment quantity, disposal location, depth, and permit requirements. Cost can vary significantly from one project to another based on the factors involved. This is the most common question we answer for lake dredging projects. The most commonly asked questions about lake dredging relate to permitting, cost, and how long the effects of dredging will last. Dredging can be accomplished in many different ways and can be very beneficial to the lake and its owner(s). The accumulation of sediment can reduce water storage, impair navigation of boats for recreation, increase eutrophication and algae, reduce aquatic habitat, and diminish property values surrounding the water. Dredging is the solution to removing the silt from the water. Dams and other impoundments that create the lake allow water to slow from flowing rapidly and sediments drop out based on the size and type. Sedimentation is the process where incoming dirt, debris, trash, and other materials are deposited in a lake once the velocity of the flow slows enough to allow it to stay in place. Lakes can vary dramatically is size but all lakes have a source(s) or tributary from where the water flows into the lake. Lake dredging refers to the removal of sediment, silt, or muck from the bottom of a lake. ![]()
