As a lake and pond dredging contractor, Dragonfly Pond Works has experience assessing lakes and ponds with various levels of sediment accumulation. Sediment accumulation reduces a pond’s storage capacity, and can lead to problems with appearance, odors, and increased nuisance vegetation. In some cases, it can lead to compliance violations with local ordinances and stormwater regulation. Our dredging experts were recently contacted to assess a Charlotte community pond. Silt had accumulated in the upper area of the pond, which was adjacent to a footbridge over the pond and highly visible. Unfortunately, access to the area posed a challenge.

Access to the area was blocked off by a stream on one side and homes on the other. This eliminated the conventional solution of utilizing excavators and large mechanical equipment. Our dredging team decided to deploy our hydraulic dredge, the DINO 6. Our hydraulic dredging capabilities provided a cost-effective and low-impact solution for our client. We were able to launch the dredge with very little disturbance to the site.

Restoration Process:

Our crew secured geotextile de-watering tubes, Geobags, in a nearby staging area. The geotextile material allows water to escape while holding dredged sediment inside to dry. Using long, narrow de-watering tubes allowed us to pump a large volume of sediment into a small area with little disturbance or damage to trees in the area.

Our hydraulic dredge passes through the water pumping excess silt directly into the Geobags on the shore. This particular dredge can pump material at a rate of 1500 gallons per minute. As a dredging contractor, this machine is an efficient solution for our clients.

The excess sediment is captured in the de-watering tube, while water is allowed to flow back into the pond. Additional bags are added and stacked to be filled as dredging continues.

The silt that was visible above the water has been removed. The DINO 6 continues to easily maneuver through the water to dredge the bottom and slopes to the desired depths.

Dredging Contractor: Silt Removal From Site

The use of de-watering tubes allowed the team to pump and stockpile approximately 650 cubic yards of silt in a relatively small area, where it was contained and left to dry.
