Hi "A system for mapping Riparian Areas in the Western United States" can be downloaded from the US Fish and Wildlife Service website
http://www.fws.gov/wetlands/ There is much information on the above website for wetlands, including wetlands mapper. The city of Davis, California has a '400 acre Davis wetlands project'). Anybody interested here is the link with updated information http://www.ci.davis.ca.us/pw/water/wetlands.cfm They do a great job.
