Multibeam surveys from USGS cover Crater Lake, Lake Tahoe and Mono Lake, and reservoir surveys from the Texas Water Development Board and the Bureau of Reclamation cover selected reservoirs. NOAA’s National Bathymetric Source adds measured depths for hundreds of lakes, lagoons and coastal ponds, from Lake Pontchartrain and the St. Johns River lakes to Lake Washington and Lake Pend Oreille; only the surveyed parts are used. NOAA nautical charts add Lake Okeechobee, Lake Champlain, the New York canal lakes and Michigan’s inland and harbour lakes from charted contours and soundings. Minnesota has its own page.
Each lake name below opens the studio framed to that lake’s survey area and generates its terrain. You can also search every surveyed lake or browse other regions.
Lakes with surveyed depth data
Sacramento County
- Sherman Lake About 88% of the lake is surveyed. NOAA National Bathymetric Source survey cells only; modelled fill is removed and uncovered parts use the basin model. Depths are below the surveys’ chart datum (MLLW on tidal water, low-water datum on the Great Lakes), not a live water level.
- Unnamed lake, Sacramento County Interpolated from NOAA nautical chart contours and soundings, which are generalized for navigation. Depths are below the chart sounding datum (MLLW on tidal water), not a live water level.
- Unnamed lake, Sacramento County About 60% of the lake is surveyed. NOAA National Bathymetric Source survey cells only; modelled fill is removed and uncovered parts use the basin model. Depths are below the surveys’ chart datum (MLLW on tidal water, low-water datum on the Great Lakes), not a live water level.
Contra Costa County
- Unnamed lake, Contra Costa County About 95% of the lake is surveyed. NOAA National Bathymetric Source survey cells only; modelled fill is removed and uncovered parts use the basin model. Depths are below the surveys’ chart datum (MLLW on tidal water, low-water datum on the Great Lakes), not a live water level.
- Unnamed lake, Contra Costa County About 97% of the lake is surveyed. NOAA National Bathymetric Source survey cells only; modelled fill is removed and uncovered parts use the basin model. Depths are below the surveys’ chart datum (MLLW on tidal water, low-water datum on the Great Lakes), not a live water level.
Los Angeles County
- Unnamed lake, Los Angeles County About 99% of the lake is surveyed. NOAA National Bathymetric Source survey cells only; modelled fill is removed and uncovered parts use the basin model. Depths are below the surveys’ chart datum (MLLW on tidal water, low-water datum on the Great Lakes), not a live water level.
San Joaquin County
- Unnamed lake, San Joaquin County About 95% of the lake is surveyed. NOAA National Bathymetric Source survey cells only; modelled fill is removed and uncovered parts use the basin model. Depths are below the surveys’ chart datum (MLLW on tidal water, low-water datum on the Great Lakes), not a live water level.
Solano County
- Unnamed lake, Solano County About 93% of the lake is surveyed. NOAA National Bathymetric Source survey cells only; modelled fill is removed and uncovered parts use the basin model. Depths are below the surveys’ chart datum (MLLW on tidal water, low-water datum on the Great Lakes), not a live water level.
- Unnamed lake, Solano County About 86% of the lake is surveyed. NOAA National Bathymetric Source survey cells only; modelled fill is removed and uncovered parts use the basin model. Depths are below the surveys’ chart datum (MLLW on tidal water, low-water datum on the Great Lakes), not a live water level.
Make a lake map from this data
- Open a lake from the list. The studio frames its survey area, turns on Water depth and generates the terrain. Widen the frame and regenerate if you want more shoreline.
- Check the warnings above the preview. The studio warns when survey coverage is partial or depths are estimated; how lake depths work explains why.
- Enter your sheet thickness in Terrain layers; the studio works out the layer count. If a deep lake needs more sheets than you want, Fit depth compresses it while keeping the shoreline. The custom lake map guide walks through the whole build.
- Turn on paint templates to spray only the water on each layer, and split the map if it is bigger than your laser bed.
- Export the SVG layers. The download’s ATTRIBUTION.txt credits the survey used.
