Key Watersheds in the Southeast Coast I&M Network (SECN) - Individual Watershed/Subwatershed Boundaries

Published by National Park Service | Department of the Interior | Catalog Last Checked: August 01, 2026 at 03:57 AM | Dataset Last Updated: January 01, 2009 at 12:00 AM
This dataset consists of the individual watersheds/subwatersheds that contain water features that flow or contribute to those that flow directly into SECN parks. The watersheds/subwatersheds are displayed and described at the HUC-10 (Watershed) or HUC-12 (Subwatershed) level; attributes have also been added to provide the HUC-2 (Region), HUC-4 (Subregion), HUC-6 (Basin), and HUC-8 (Subbasin) numbers and descriptions of each watershed/subwatershed. Furthermore, the individual watersheds/subwatersheds are grouped by park so as to create an overall custom drainage basin for each park. If individual watershed/subwatershed boundaries are not needed, please refer to the dataset titled 'Key Watersheds in the Southeast Coast I&M Network (SECN) - Custom Drainage Basin Boundaries' in order to access the overall custom drainage basins as single polygon shapefiles. Note: for the purposes of this dataset and for the remainder of this metadata file, the term "watershed" will refer to individual watershed/subwatershed units while the term "drainage basin" will refer to the collection of individual watershed/subwatershed units that contribute to the condition of each park.
