This dataset represents swallets (stream to sink features) discovered, researched and mapped by the Florida Department of Environmental Protection, Florida Geological Survey, Florida Swallet Survey. The Florida Swallet Survey was a mapping program funded by the Florida Department of Environmental Protection's Florida Springs Initiative. A swallet is a stream to sink feature, meaning there is a contribution area that concentrates runoff into identifiable streams that disappear underground at a specific point through a sinkhole. The streams may be either intermittent or continuously flowing. Data collected includes: GPS points from a Trimble ProXR and TSC-1 Data Logger; length and width of pools and basins using a range finder; pool depths, if possible, using a hand-held sonar depth finder; color, clarity and visibility of the water in the pool using a secchi disk; photos were taken and written assessments were made of the geology, topography, vegetation, and notations of anything within a 150-meter radius. This dataset represents swallet locations that were within the scope of the Florida Springs Initiative / Florida Swallet Survey project. As such, not all Florida swallets are included in this dataset, and it is by no means comprehensive. |
