Of primary interest to the South Florida Water Management District (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.

Vertical accuracy is +/- 8 cm (3 in). Lineage: Process_Step: Process_Description: The USGS has developed a hydrographic survey system specifically designed to map in very shallow water. A survey quality 200 kHz depth sounder was used to acquire water depth measurements and a motion sensor measured heave, pitch, and roll of the boat. A measurement was collected every second or about every 3 m (10 ft) along a survey line. To achieve horizontal accuracy of +/- 4 cm (1.6 in) and vertical accuracy of +/- 8cm (3 in), the boat could not be operated more than 20 km from any one GPS base station. It was anticipated that two GPS base stations would be used. Several new survey benchmarks were established around the lake perimeter for GPS base station occupation. Survey track line spacing was 1000 m apart oriented in a north-south direction. A perimeter survey line and several east-west lines were collected also. In addition random crossing lines were collected daily. Crossing lines were used to crosscheck and verify the survey. Soundings were collected along each track line at 3 m (10 ft) spacing. A minimum of 1550 kilometers of survey line were collected. In shallow areas, data were collected in a minimum of 2 feet water depth except where there was potential damage to the bottom environment or the boat/motors.
