Data from each of the three counties is extracted from the service that each county offer and complied into one feature.Each county is responsible for their own data that they provide in their service.

The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.

A Building Line has been established along the coast as part of the Regulations Governing Beach Protection and the Use of Beaches. The Building Line, which parallels the coastline, is designated on DNREC maps. No construction may take place seaward of the Line without a Coastal Construction Permit or Coastal Construction Letter of Approval from the Department of Natural Resources and Environmental Control(DNREC)

This water is derived from the USGS/NHD Dataset, August 2014. The water that is in this datasets is taken from the USGS/NHD dataset. Streams that are designated as "artificial paths" have either been renamed to match the flow path they are related with, or have been removed. Artificial paths are parts of a stream that may run under a building, road or through a pond to maintain flow direction that is built into the original USGS/NHD flow dataset.
