However most projects can have a dramatic impact on a lake within the cost range of 50,000 to 250,000. Therefore, the cost to dredge a lake ranges from 5,000 to 5,000,000.
Many times, because of pumping or hauling costs, the muck is discarded so close to the water body that the matter and nutrients can just drain right back in. Limited space, time, and type of sediment slows the process of turning a completely sloppy mud into dirt you can grade or transport efficiently. However, dredging can be hazardous in some environments, prohibitively expensive, and can release pockets of phosphorus and nitrogen found in the underlying muck layers into the water column. Specifically, the phosphorus and nitrogen found in the muck are physically removed from the aquatic environment. An advantage of dredging is the process removes both the organic and inorganic compounds. Hydraulic dredging involves suction equipment that takes a slurry of muck and water off the bottom and sends it via pipeline to another location to be discarded. Mechanical dredging involves the use of heavy equipment, an excavator for example, that scrapes the muck off the bottom and discards the material onto a waiting barge or the shoreline. Dredging comes in two basic forms: mechanical and hydraulic. at an average cost of 1.1 cents per kilowatt - hour. The cost in many cases is prohibitive and most mechanical dredgers will not even. The most common treatment for muck is physical removal by dredging. The elevation of the dredge pond at the present time is 27 feet above the. This gradually fills in the pond and is the direct cause of the many.
