Bathymetric Surveying for Docks, Dredging, and Waterfront Projects
We map what’s under the water, not just what’s around it. Using a boat-mounted echo sounder tied to GPS, we chart depth and floor elevation across ponds, rivers, and coastline. Our team has been doing this for over 20 years; we’ve just traded waders for a boat along the way.
Sonar Data You Can Actually Trust
Our BathyCat echo sounder pairs with GPS to log water depth and floor elevation as we move across a site, running overlapping passes so the data cross-checks itself.
In side-by-side testing against old-school, wader-based manual measurements, it’s held up within 2 inches.
That’s not a marketing number, that’s what we checked against ourselves.
Residential, Commercial, and Municipal Projects
Bathymetric surveys show up across a wide range of work:
-
Dock construction and dredging projects for homeowners
-
Bridge and structural engineering projects built over water
-
Pond restoration and municipal waterfront work
-
Marine contractors and engineers who need existing-conditions data before design starts
We’ve worked this water throughout Connecticut and New York, including out at Fisher’s Island and Long Island.
Over 20 Years on the Water
We were running bathymetric surveys before most of today’s sonar technology existed to make it easier. That history, paired with modern equipment, means there’s very little we haven’t already handled, from a single residential dock to a full municipal pond restoration.
Frequently Asked Questions
What is the difference between a bathymetric and hydrographic survey?
Bathymetric surveying maps water depth and underwater terrain. Hydrographic surveying adds tides, currents, and navigational hazards on top of that. We focus on bathymetric work, but can pull in hydrographic elements depending on what your project needs.
How accurate is the data?
Verified within 2 inches against manual, wader-based measurements in direct testing, side-by-side.
Do I need any special permits for this?
Most standard projects don’t require special permitting. Larger open-water work can involve additional Coast Guard considerations, which we’ll walk you through case by case.
