Each scenario is different, and there are several factors to consider. However, you can expect between $25-$90 per cubic yard.
Aquatic South recommends using this cost range model to build out your own high, medium, and lower forecasted dredging cost calculator.
Assume for your forecast that you’ll be removing 500 cubic yards. Our team has highlighted a few tips on how to lower your dredging costs, as well as techniques our team utilizes to minimize impacts on fish populations.
The highest cost for these projects is always in trucking the spoils offsite to be disposed of at the closest landfill.
Trucking costs can be between $325-$400 per truck, depending on the distance to the dump site, type of material, and fuel costs. If there is a way to keep the spoils on site, you can save considerable amounts of money on the project.
Oftentimes it is obvious that your pond is filling up with sediment due to erosion upstream, naturally occurring run-off and decaying vegetation.
You may see your pond shrinking or islands forming near the inlets.
We recommend starting with a survey completed by one of our partners or us. We can determine the average sediment accumulation throughout your pond.
These are bathymetric surveys that will provide a foundation for determining how many cubic yards to remove in order to restore your aquatic environment back to its original depth.
The short answer is no.
We can mechanically dredge your pond at full pool. However, this can add complexity and cost to the project depending on the current depth, etc.
Rarely if ever, does the pond need to be completely drained to perform the work.
One primary advantage is that it helps de-water the muck, allowing for shorter drying times prior to either spreading the spoils onsite or hauling in trucks, thus lowering the overall cost of the project.
The second advantage is we can see exactly what we are doing, and you can clearly see the progress in real-time.
You will see how the project is taking shape, the impact we are making, and how much is being removed.
There are some exceptions, but almost every single pond and lake in Georgia is man-made, and most serve as detention/retention ponds.
The depth of a healthy pond is typically considered to be 3-4 feet at the lowest, with it gradually gaining depth in the middle or near the dam.
However, water runoff draws sediment into your pond, which accumulates at about 1 inch per year. Sometimes you can clearly see the results of your pond filling with sediment/muck.
Other times, you may see secondary effects such as additional aquatic vegetation growth, poor water quality, or even dying marine animals and fish.
Restorative dredging usually takes place every 5-15 years, depending on your watershed, erosion, and additional run-off.
