Summary
Abstract: The National Hydrography Dataset (NHD) is a comprehensive set of digital
spatial data that contains information about surface water features such as

water features are combined to form "reaches," which provide the framework for
linking water-related data to the NHD surface water drainage network. These
linkages enable the ... View entire text
