Hmm, once or twice a year seems a little excessive. From experiences I've had, every 10-15 years is more likely. Diver-operated dredging runs in the range of $250-$750/cubic yard, including materials and disposal. In the demonstration video, it shows the diver removing approximately 2' of sediment from the bottom of the pond. The pond the divers are working in it neighborhood of 3 acres in size. Doing the math on the conservative side, that would make the dredging of this pond in the range of $2.5 million. I don't think there are many people that are going to be doing that on a semi or even annual basis. Performing bathymetric surveys would be a good first step in determining if a pond needs to be dredged and will inform you as to how much material will need to be removed so you can budget for it. It's a good idea to do post-dredging bathymetric surveys as well to verify that the correct amount of sediment was removed during the project.
Hello Norm, it’s hard to say how many times to recommend dredging frequency. Generally speaking 3 to 10 year range would be suffice. We take the position that the pond owners do not like to get hit with rather large costs that are associated with waiting 10 to 20 years when the job could become potentially massive in costs and disposal. Ultimately dredging frequency all depends on how much material is coming in due to construction sites, general erosion, leaves and just basic sediment. The cost per cubic yard that you mentioned I’ve actually never even heard of numbers that high. I have spent many years working offshore running bathymetric survey systems as well as some inland projects. They are not fullproof and leave a wide array of inaccuracies that usually cause potential problems between the contractor and the client. Side scan sonar systems do not accurately decipher the amount of sediment, mud, rocks that are deposited on the natural “original” contour of the pond bottom. I encourage you to watch our video how to properly probe a pond. Obviously large massive bodies of water will need a side-scan sonar. Thank you very much for watching our video and appreciate the dialogue be careful stay safe👍
Randy, logistical setup is a significant cost in a project and you're not taking that into account, only the volume of material being removed. Assuming the rate the lake is filling with sediment is constant, here is an example. If 100 cubic yards of material accumulates annually, removing that after one year involves the price of getting the contractor on site (basically fixed) and the cost/hour that sediment can be removed (basically fixed). If you do it again the next year, you have both of those same costs. But, if you wait and do it after two years, you only have one setup cost. It is still going to take basically the same amount of time for the contractor to remove the sediment, whether they do it in two 100 cubic yard removals or one 200 cubic yard removal. So, it's cheaper in the long run; in essence, like buying in bulk. It is incumbent on budgeting though for that larger (but cheaper per unit cost) expenditure.
You can try to clean the lake on your own and without a diver. It is enough to have a motor pump for mud and a suction nozzle for a mini dredger Bagermaster
sedimont removal system (a company im apart of) is a much cheaper option for home owners, HOA, golf course owners and more as we are much cheaper and we are not considered dredging as all we are doing is CLEANING the pond and restoring it back to its former glory
This is the proper way, good job guys!!

And another thing is if u do it more often u don’t have as much to get rid of so then your cost is going to b less

Way too excessive. lol

Wow, I've never seen anything like this, what an incredible job! How much mud can you dredge like this in a day? It must be very tough for the divers!
2,300 gpm is the ability of the pump but it all depends on resources and safety of the workers.
Tanner forgot the suction hose
Cool video!
Glad you enjoyed it
Has your diver ever used a Bagermaster suction nozzle?
Can you recommend a company in Ohio that can do this job.... Great video.... Great information.... Thank you
Yes we can.. please email us so we send you the information.
Call or email us 👍🏻
