Modeling the bathymetry of Catahoula Lake: Specialized technology for wetland management

Abstract

Catahoula Lake is the largest natural freshwater lake in Louisiana, covering more than 46 square miles (120 km2) (fig. 1). The lake is a principal stopover and wintering site for hundreds of thousands of migratory waterfowl and shorebirds. Scientists from the USGS National Wetlands Research Center are applying some of the research facility's specialties?wetland plant research, aerial and ground surveys, digital mapping, and computer modeling?to facilitate wetland management at Catahoula Lake.
