ABSTRACT: Bathymetric and sedimentation surveys were conducted using a dual frequency (28/200 kHz) echo sounder system in two reservoirs (Lee Creek Reservoir and Lake Shepherd Springs) in the Ozark Plateau of northwestern Arkansas. Echo sounder survey data were merged within geographic information system (GIS) software to provide detailed visualization and analyses of current depths,
and a global positioning system (GPS) receiver and measuring tape were used to determine location and distance for mapping. In September and October of 2002 as water level elevation was returning to 167.6 m Costa Rica satellite remote sensing and empirical curves. By Dr. Sumedha Chakma,
respectively it is possible to assess quantities and rates of reservoir sedimentation. This data collection project was in cooperation with the Nebraska Department of Environmental Quality (NDEQ).
