Service Description: The NHD is a national framework for assigning reach addresses to water-related
entities, such as industrial discharges, drinking water supplies, fish habitat areas,
wild and scenic rivers. Reach addresses establish the locations of these entities
relative to one another within the NHD surface water drainage network, much like
addresses on streets. Once linked to the NHD by their reach addresses, the
upstream/downstream relationships of these water-related entities--and any
associated information about them--can be analyzed using software tools ranging
from spreadsheets to geographic information systems (GIS). GIS can also be used
to combine NHD-based network analysis with other data layers, such as soils, land
use and population, to help understand and display their respective effects upon
one another. Furthermore, because the NHD provides a nationally consistent
framework for addressing and analysis, water-related information linked to reach
addresses by one organization (national, state, local) can be shared with other
organizations and easily integrated into many different types of applications to the
benefit of all.

Description: This data set contains regions representing areal NHD hydrographic waterbody features. Basic waterbodies such as lake/pond features are represented here. They portray the spatial geometry and the attributes of the feature. These water polygons may contain NHDFlowline artificial paths to allow the representation of water flow. Other NHDWaterbody features are swamp/marsh, reservoir, playa, estuary, and ice mass. 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. Medium resolution NHD is based on the content of the U.S. Geological Survey (USGS) 1:100,000-scale Digital Line Graph (DLG) hydrography data, integrated with reach-related information from the U.S. Environmental Protection Agency Reach File Version 3.0 (RF3). The FDEP is the NHD data steward for Florida. When received from FDEP, this data was originally in geodatabase format. When in shapefile format the data loses the network functionality of the geodatabase. Please contact the FDEP if you need the original geodatabase.
