Resource Abstract:
- description: Lake Okeechobee is located in south Florida and is bounded by the Kissimmee River Basin to the north and Everglades
National Park to the south. Lake Okeechobee is the largest lake (1890 km2) in Florida and encompasses a drainage area of over
14,200 km2. The lake provides agricultural water supply, back-up water supply for urban areas, flood protection to adjacent
communities, critical bird and fisheries habitats, is part of the Okeechobee Waterway navigation canal, and boating recreation.
Over the past 100 years, land use change and population increases have adversely impacted the health of the lake mostly by
extreme water level fluctuations and excessive nutrient loading mostly from agricultural activities. High-resolution bathymetric
mapping was conducted in 2001 in Lake Okeechobee by the USGS, in cooperation with SFWMD. High-resolution, acoustic bathymetric
surveying is a proven method to map sea and lake floor elevations. Survey tracklines were spaced 1000 meters apart and orientated
in a north-south direction. Tracklines collected in an east-west orientation (intersecting tracklines) functioned to serve
as a cross-check and to assess the relative vertical accuracy of the survey. Ideally, vertical data values at the crossing
should be exactly the same. In reality, this is not always the case due to random errors of survey system. Several perimeter
survey lines were also collected. Soundings were collected along each trackline at 3-meter spacing. Approximately 1,550 kilometers
of survey lines were collected. In shallow areas, data was collected in a minimum of 0.6 meters water depth except where there
is potential damage to the bottom environment or the boat/motors was a significant possibility. This report serves as an archive
of processed single-beam bathymetry data that were collected in Lake Okeechobee, Florida in 2001. Geographic information system
data products include XYZ data, bathymetric contours, USGS quadrangle maps, and associated formal Federal Geographic Data
Committee (FGDC) metadata.; abstract: Lake Okeechobee is located in south Florida and is bounded by the Kissimmee River Basin
