George William Stephens, Jr. and Associates, Inc. (GWS) is pleased to announce the addition of a new service, Bathymetric Surveys. In addition to conventional and GPS survey data collection, GWS also performs Bathymetric Surveys of ponds, lakes, rivers and other water bodies. We utilize GPS equipment along with a sub-surface measuring device to accurately map the "beds" or "floors" of water bodies.

Information gathered is used to determine volumes of dredged material, available storage of ponds or storm water management facilities, design of bridge placements at water crossings and more.

For additional information, or a bathymetric quote, please contact our survey department at 410-297-2340.
