Water Resources Maps and GIS Information http://water.usgs.gov/maps.html A link to 12 data sources with map data from the USGS or organizations connected with the USGS.

Hydrologic Unit Maps (HUC)

Description http://water.usgs.gov/GIS/huc.html

Get the data http://water.usgs.gov/lookup/getspatial?huc250k

The 8-digit hydrologic cataloging units are the basic water resources subdivision of the United States

EPA Reach File 1 (RF1), Version 2.0

Description http://water.usgs.gov/GIS/metadata/usgswrd/XML/erf1_2.xml

Get the data http://water.usgs.gov/GIS/dsdl/erf1_2.e00.gz   It used to be that you could get RF1 for each 2-digit water resources region of the nation separately, but it appears that is no longer the case, and this file contains RF1 for the whole nation.
