PHASE: PLANNING
Site visit and estimate
It starts with a call or an email. We look at your water, talk through what you are seeing, and give you a straight estimate on the work and how long it will take. No pressure, no surprises.
Our process
OP SEQUENCE 01-05 · SECTION VIEW A-A From lake bottom to dry land
One continuous system moves sediment from the bottom of your water into a dewatering bag on shore, and sends clear water straight back. Here is exactly how it works.
Step by step Five steps.
Five steps.
One clean operation.
Scroll to run a full job on a model of our DINO6, from the first look at your water to the bag drying on the bank.
Skip the 3D walkthroughA 3D model of the DINO6 dredge working a pond, shown in a cut-away section. Scrolling runs the job: the auger cuts the mud off the bottom lane by lane, the slurry runs through a floating pipeline to shore, polymer is added, the dewatering bag fills on the bank, clear water drains back to the pond, and the bag dries for months while the pond stays at full depth.
- PHASE: DREDGING
The auger head goes down
The dredge floats out and lowers its auger cutterhead to the bottom. The rotating auger loosens the mud and silt while the pump creates a vacuum effect that pulls the sediment up and into the discharge line. The bottom gets cut clean, pass by pass.
- PHASE: TRANSPORT
The floating pipeline carries it
From the dredge, the slurry travels through a floating pipeline: pipe sections clamped together, kept on the surface by sealed float pipes riding alongside. The line is rigged with cables so it stays exactly where we set it, all the way to shore.
- PHASE: CONTAINMENT
Ninety degrees to the bag
At the bank the pipeline makes its turn out of the water and runs onto land, straight into a geotextile dewatering bag. The bag is staged on flat, level ground and anchored in place before we ever start pumping, so everything we pull off your lake bottom ends up contained, not spread across your shoreline.
- PHASE: DEWATERING
Dewatering, polymer, and cleanup
Inside the bag, polymer treatment separates the water from the sand and mud. Clear water drains back to your lake while the solids stay behind. Our crew walks the bag to work the material and keep it draining. The bag then stays anchored in place for three to six months, until the material is fully dried and ready for final placement or haul-off.
The part nobody expects
The bag stays for three to six months
Once the dredging is done, the dewatering bag stays behind, anchored on flat, level ground, draining and drying for somewhere around three to six months before the material is hauled off or put to final use. Your water is back to full depth that whole time. The bag just needs its space on shore, and we plan that spot with you from day one.
Why it matters
What you get back
Depth comes back
Years of accumulation removed, restoring the water to its intended depth.
Water quality improves
Less muck means clearer, cooler, healthier water from top to bottom.
Habitat recovers
Fish and the ecosystem they depend on get their room back, safely.
No draining, ever
The entire operation runs while your water stays full and in use.
Common questions Asked before
Asked before
every project
If your question is not here, call us. You will talk to the person who runs the dredge.
Will you have to drain my pond or lake?
No. The whole system works from the surface. Your water stays full and usable the entire time we are dredging.
What happens to the mud you remove?
Everything is pumped into a geotextile dewatering bag on shore. Polymer separates the solids from the water, the clear water drains back into your lake, and the dried material is ready for placement or haul-off.
How long does a project take?
It depends on the size of the water and how much sediment has built up. Give us a call or send us an email and we can get you an estimate on how long it is going to be.
How long does the dewatering bag stay on site?
Plan on three to six months, depending on how much material is in it and how it drains. The bag needs flat, level ground and stays anchored in place the whole time it is working. It is the part of the project most people do not expect, so we make sure it is planned from day one.
Where can you work?
Anywhere there is enough water to float the barge. The dredge trailers to your site and launches in places full-size equipment cannot reach.
