Lake & reservoir mapping in California
California's reservoirs are the backbone of the state's water supply, and wildfire-driven sediment is changing them fast. Our volumetric and bottom-composition surveys quantify what has changed since the original capacity tables were drawn.
California has more than 1,400 named reservoirs. Lake Monitor AI provides on-site bathymetric depth mapping, aquatic vegetation mapping, bottom composition and hardness mapping, fish and habitat mapping, side-scan imagery and GIS deliverables for waterbodies of every size across the state — from private ponds to major reservoirs.

What California lake managers are dealing with
- Drought storage accounting and capacity loss
- Post-wildfire sediment and debris inflows
- Invasive Egeria densa, water hyacinth and quagga mussels
Each of these starts with an accurate map. Our surveys give you the baseline and the year-over-year comparison to act on.
