Summary
Abstract: This is a 1:2,000,000 coverage of streams for the conterminous United States.
This coverage was intended for use as a background display for the National
Water Summary program.

The stream layer was extracted from the 1:2,000,000 Digital Line Graph files.
Originally, each state was stored as a separate coverage. In this version, the
individual state coverages all have been appended.
