USGS Water Data for the Nation Site serves as the publicly available portal to a geographically seamless set of much of the water data maintained within NWIS (additional background). HYDROGRAPHY_HIGHRES_WATERBODYLINEAR_NHD_USGS.SHP is derived from the high-resolution version of the National Hydrography Dataset (NHD), which was … USGS Water Data for the Nation Site provides access to water data from over 1.5 million sites in all 50 States and additional border and territorial sites. Stream levels are useful in the retrieval algorithms which traverse the Reach File. For instance, the Mississippi River is a level-one stream, the Ohio River is a level-two stream, and the Tennessee River is a level-three stream. This map layer was formerly distributed as Hydrography Features of the United States.

The U.S. Geological Survey, in cooperation with the Missouri Department of Natural Resources, designed and operates a network of monitoring stations on streams and springs throughout Missouri known as the Ambient Water-Quality Monitoring Network (AWQMN). HYDROGRAPHY_HIGHRES_WATERBODYLINEAR_NHD_USGS.SHP is a polygon shapefile that contains features of rivers, inundation areas, canals, ditches, submerged streams and other linear waterbody areas in watersheds in and around Indiana.

To assess whether these chemicals are entering our Nation's streams, the Toxic Substances Hydrology Program of the U.S. Geological Survey (USGS) collected and analyzed water samples from 139 streams in 30 states during 1999 and 2000. A "level path" can be followed to identify all mainstem reaches of a given river.
