Service Description: This set of layers delineates the boundaries of drainage basins, watersheds, and catchments in Tallahassee and Leon County, Florida. • Drainage Basins are the largest unit of drainage and typically drain into a major lake or river in cases where there is a significant drainage network of streams present. In areas where internal drainage is the dominant mechanism of water movement basin boundaries represent limits beyond which flow does not typically occur during normal hydrologic conditions. • Watersheds are the intermediate level unit of drainage delineated in the ESA datasets, smaller than basins and larger than catchments. • Catchments are the smallest unit of drainage delineated in the ESA datasets. This dataset was originally developed in 1999 to provide members of the Tallahassee/Leon County GIS Interlocal group with base data to use in their maps, projects and business processes. The ESA Watershed Refinement Project was initiated in 2005 as a consequence of the increased accuracy of topographic data acquired through the routine basemap update project (orthophoto and LiDAR capture). To maintain an internally consistent set of data layers requires that all layers derived from topographic data be updated to reflect the current Digital Elevation Model (DEM) data both because the new DEM data is more accurate due to technology advances (LiDAR) and because the new DEM data reflects structural on-the-ground changes (construction activity) since 1996.
