National Hydrographic database (NHD)
The National Hydrography Dataset is now available in a new database design that allows better web-based access and query, as well as truly seamless data that can be downloaded in various extents. The new database design provides a distribution format called NHDinGEO. Data requests in NHDinGEO can be extracted by subbasin, county, congressional district or by topographic map quad. Pre-staged personal geodatabases by subregion are now available on the ftp site ftp://nhdftp.usgs.gov/SubRegions. Select the High, Local, or Medium folder. See also http://nhd.usgs.gov/data.html
