Over a period of time leaves, weeds, algae and other organic matter accumulate in your pond or lake, taking the form of “MUCK”. As the amount of this material increases over the years the waterway starts to experience many problems. MUCK harbors nutrients that can cause excessive weed and algae problems, and deteriorates the water quality and ecosystem of your lake or pond. Now Lake and Wetland Management offers a unique, low-impact method of removing these unwanted sediments and restoring new life to your lake or pond.
Mechanical dredging is most effective when the lake or pond has been completely drained and the sediments have had time to dry. This means all aquatic life must be relocated. If the waterway is dredged wet, as soon as the dredge bucket hits the sediments, they explode into the water column releasing toxic gases and nutrients. This leaves the lake or pond a black, mucky mess. Once the dredging is completed, the sediments then settle back to the bottom of the waterway and much of the dredging benefits are lost. Mechanical dredging requires that the removed material either be placed on the shoreline for drying which can create a strong odor and complaints from community residents or hauled away wet which can increase trucking costs and make a mess on community streets. Heavy equipment can cause extensive damage to the landscape and is hindered by houses, power lines and trees. The cost of mechanical dredging in many cases is prohibitive and most mechanical dredgers will not even consider smaller lakes or ponds.
The ENVIROdredge process uses specialized, portable equipment with a high volume suction pump to “vacuum” the sediments from the waterway. The sediments are then pumped into Geotextile Tubes strategically placed onsite up to 1,000 feet away for dewatering. After the sediment is fully dewatered it can then be hauled away or spread onsite as fertile, organic topsoil. There is significant cost savings in hauling away dried material verses wet material. In most cases the water filtered from the Geotextile Tube is returned to the waterway. The dewatered sediments can also be used as fill material for our Shore Sox system to restore eroded areas along the lake or pond shoreline. The ENVIROdredge process not only removes the sediments, toxic gases and nutrients in an environmentally sensitive way but is also an extremely low-impact and cost-effective method of cleaning your lake or pond.
