Field Activity 2001-301-FA

Identifier 2001-301-FA
Purpose High-resolution bathymetric mapping was conducted in 2001 in Lake Okeechobee by the USGS, in cooperation with SFWMD. Of primary interest to the USGS and SFWMD is the quantification of the present day lakebed in Lake Okeechobee. This information can be used by water management decision-makers to better assess the water capacity of the lake at various levels.
Location Lake Okeechobee, FL
Summary Single-beam bathy lines (272); Raw GPS data from base stations (205 files) and boat (119 files); Raw GPS in Rinex format (116 base files, 87 boat files); Processed soundings (519,383) in comma-delimited and Esri point shapefile formats
Info derived Single beam bathymetry (x,y,z) data. Products are ASCII text files of the sounding data and point shapefiles representing seafloor elevations. Differential GPS (DGPS) data files for precise navigation.
Comments Additional Staff: Russel Peterson The survey area covered all of Lake Okeechobee except portions of the eastern section where water depths were insufficient for safe boat operations. All data were processed relative to the WGS84 (G1150) ellipsoid. Operation personnel were used to assist in surveying and staff rotation. Digital FACS logs were generated by N.T. DeWitt in March 2018 using the handwritten logbook to comply with data archiving requests.
