Description: The New Hampshire Hydrography Dataset (NHHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the state's surface water drainage system. The NHHD, developed at 1:24,000 scale, is an extract from the high-resolution National Hydrography Dataset (NHD) housed at the US Geological Survey. The NHHD Shapefile Extract contains the NHDFlowline feature class from the original NHHD geodatabase. The shapefile covers the extent of the sixteen cataloging units that intersect the State of NH, and contain reach codes for networked features, stream order, flow direction, names, and centerline representations for areal water bodies. However, because this data is no longer contained in the original geodatabase, the networking capabilities of the NHDFlowline has been lost.
