What lies beneath Lake Tahoe?The Lake Tahoe Bathymetry Mapping Project is a collaborative effort between
the U.S. Geological Survey (USGS) Water Resources, National Mapping, and
Geologic programs. A bathymetric survey of Lake Tahoe was conducted on
August 1998 using the latest-generation multibeam system by the The bathymetry survey of Lake Tahoe is a special project conducted to study the terrain of the lake floor. The multibeam mapping system records both the bathymetric data (depth information) and the backscatter data (the strength of sound energy that bounces back). This information can help scientists identify the materials that make up the lake floor, such as rock, sand, or mud. New data can shed light on the history hidden by the waters of Lake Tahoe.
