Description: Point shapefile depicting Chesapeake Bay Nutrient Monitoring sites in the Susquehanna River Basin. These points include 'Group A' and 'Group B' sites. These points are used in the Susquehanna River Basin Commission's "Susquehanna Nutrient Assessment Program."

Description: Dataset represents the main stems of the Susquehanna River Basin including the Susquehanna River, West Branch Susquehanna River, Juniata River, and Chemung River. This dataset also includes the Cohocton River, Raystown Branch Juniata River, and Frankstown Branch Juniata River in order to display a more widespread coverage. The high resolution National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nations surface water drainage system. High resolution NHD 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.) Like the 1:100,000-scale NHD, high resolution NHD contains reach codes for networked features and isolated lakes, flow direction, names, stream level, and centerline representations for areal water bodies. Reaches are also defined to represent 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 set out by the Federal Geographic Data Committee.
