we have the data, we have the people, we have the technology...
Spatial analysts at the MD-DE-DC WSC use Geographic Information Systems to interpret data collected through field reconnaissance and downloaded from internal USGS, other federal, state, and local agencies, academic institutions, industry, and other professional contracting organizations. GIS is used to analyze the data using shapefiles and geodatabased information to help prove or disprove hypotheses and enhance deliverables by visualizing the data in the form of thematic or point-referenced interactive web products so they are easily understood, we use our geospatial expertise to create products that are focused on advancing our science and meeting our cooperators’ needs.
Metadata Record: NHDPlus V2.1 Reach Catchments and Upstream Watersheds
Attributes for NHDPlus V2.1 Describing a series of data sets of natural and anthropogenic features linked to NHDPlus Version 2.1’s nearly 2.7 million stream segments, catchments, and their upstream watersheds within the conterminous United States

The USGS is in the forefront of automatic, online data processing with the ability to store processed data for live, Web-based and journaled investigative reports supported by archived data, maps, and appendices.
Floodplain Ecosystem Service Mapper
Healthy floodplains and wetlands provide critical ecosystem services to local and downstream communities by retaining sediments, nutrients, and floodwaters. Land conversion and degradation diminish floodplain functionality and services.
Hydrologic Unit Maps
The U.S. is sub-divided into successively smaller hydrologic units which are classified into four levels: regions, sub-regions, accounting units, and cataloging units. Each unit is identified by a unique hydrologic unit code (HUC) consisting of two to eight digits based on its classification. This site provides information and data for current and historical hydrologic units, names, and numbers.

Dissolved Solids Sources, Loads, and Yields For the Conterminous U.S.
Using the SPARROW (SPAtially-Referenced Regression on Watershed Attributes) model, long-term mean annual conditions for dissolved-solids sources, loads, and yields were predicted for nearly 66,000 stream reaches and their corresponding incremental catchments that drain the Nation.
Eastern United States 2002 Nutrient Loading
The U.S. Geological Survey applied the SPARROW model to assess the loads delivered in 2002 for estuaries and coastal waters along the Atlantic Ocean and eastern Gulf of Mexico.
