Information of interest to watershed managers, researchers, and the general public is available free of charge on the Internet through World Wide Web. The number of Web sites that address watershed issues and information is so great that it is impossible to provide a complete catalog. The purpose of this appendix is to provide a brief list of sites representing examples of the types of information available. Links embedded within these sites allow the user to access other related sites. The following list includes sites that are primarily data sources as well as examples of sites maintained by watershed management agencies from the local to the national level. All the sites were active as of September 30, 1998.
