National Hydrography Dataset (NHD) definition:National Hydrography Dataset (NHD) definition: The NHD is a comprehensive set of digital spatial data that contains information about surface water The NHD is a comprehensive set of digital spatial data that contains information about surface water

features such as lakes, ponds, streams, rivers, springs and wells. The NHD interconnects and features such as lakes, ponds, streams, rivers, springs and wells. The NHD interconnects and uniquely identifies the stream segments or reaches that make up the Nation's surface water uniquely identifies the stream segments or reaches that make up the Nation's surface water drainage system. The NHD is a national framework for spatial position or surface water features, drainage system. The NHD is a national framework for spatial position or surface water features, their attribution, their connectivity in a flow network, and an addressing system of linking additional their attribution, their connectivity in a flow network, and an addressing system of linking additional related data known as events. Each reach in this framework is referenced by a permanent feature related data known as events. Each reach in this framework is referenced by a permanent feature identifier known as a reach code. Each linear reach is also segmented into linear addresses identifier known as a reach code. Each linear reach is also segmented into linear addresses measures along the reach. The USGS is the authority for reach codes and measures. Because the measures along the reach. The USGS is the authority for reach codes and measures. Because the NHD provides a nationally consistent framework for addressing and analysis, water-related 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 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 other organizations and easily integrated into many different types of applications to the benefit of all. all.
