Hydrographic surveys that map what lies beneath the water
Bathymetric surveys on rivers and lakes, with production of profiles. Talk to our team about your site, timeline and the standard your project must meet.
Why hydrographic surveys matters
Intakes, bridges, jetties and hydropower schemes all depend on knowing the shape of the river or lake bed. Bathymetric data reveals depths, channels and sediment so designers can place structures with confidence.

Our process
Step 1: Planning
We define survey lines, spacing and the control needed on the shoreline.
Step 2: Water survey
Depth soundings are captured along planned lines and tied to shore control.
Step 3: Processing
Soundings are cleaned, reduced to datum and modelled.
Step 4: Profiles and charts
We deliver cross sections, long profiles and bed contour plans.
Benefits of working with COGO
Safer structures
Foundations and intakes are placed on known ground.
Better hydraulics
Profiles support flow and capacity modelling.
Clear records
A baseline for monitoring sediment and bed change.
“Good water projects start with a clear view of the bed.”
