Bathymetry Survey Explained

High-Resolution Lake Depth & Volume Mapping

What Is a Bathymetry Survey?

A bathymetry survey is a depth-mapping assessment that produces a detailed model of your lakebed. Using drone-assisted sonar technology, the survey captures depth data across the full waterbody and generates contour maps and volume calculations.

It establishes a clear baseline of your lake’s underwater structure.

What Problem Does It Solve?

You should consider a bathymetry survey when:

• Planning dredging or sediment removal

• Estimating muck volume

• Investigating sediment buildup

• Updating outdated depth maps

• Supporting internal loading or nutrient modelling

• Establishing a depth baseline before intervention

Without accurate depth data, planning becomes assumption-based.

What Data Do You Receive?

Outputs typically include:

• Depth contour maps

• Digital elevation models of the lakebed

• Volume calculations

• Sediment accumulation indicators (where applicable)

• Processed imagery and supporting documentation

All deliverables are provided digitally and accessible via the Lake Pulse Portal.

How It Works

1. Exploratory scoping call

2. Mission planning and access coordination

3. Drone-based sonar survey

4. Data processing and modelling

5. Delivery of maps and summary outputs

Surveys may be repeated over time to measure sedimentation trends.

When Should You Use It?

Bathymetry is most valuable when:

• Budgeting for dredging

• Seeking grant funding

• Planning restoration projects

• Establishing long-term monitoring baselines

• Validating previous depth assumptions

Summary

A bathymetry survey provides the structural foundation for lake management planning. It replaces assumptions with measurable depth and volume data.
