The third technique was to drain the lake and let it dry so that heavy equipment such as bulldozers and earth-moving pans could reshape the pond bottom and use the excess material to make an island or peninsula within the lake.
This type of equipment may be suitable for large lakes that are accessible by heavy equipment and where the shoreline area can be allowed to “heal” over time. The material was then pumped offsite to dry and be hauled away using heavy equipment. The second technique involved a large dredge that often had to be lifted into the lake with a crane. Can you imagine trying this in a developed subdivision? Not only was this method inefficient, but it made a big mess and required areas around the lake shore that could be accessed by heavy equipment. The first was to physically remove the wet material utilizing draglines or large track hoes and haul this wet material away from the site in large dump trucks. In years past, there were basically three techniques to evacuate material from lakes and ponds. Of the dredging barge can carry silt and detritus for more The flexible discharge hose attached to the hydraulic pump Water leaches out of the synthetic fabric of the bags allowing the solid material to dry and be easily disposed of at a later time. This material can be easily removed by new hydraulic dredging techniques that deposit sediment in Geo-bags up to a thousand feet from the dredge site. Not only are these silted areas esthetically unpleasing but there is a loss of fish spawning areas and valuable fish habitat. These areas often begin to vegetate and become unsightly. Many of us have seen small ponds or upper ends or sloughs of larger lakes gradually fill in with silt to form extremely shallow areas or even islands.
