Basin Plan Maps - Supplemental

Five separate maps have been created that represent all water bodies listed in the Basin Plan. At this time, these maps have not been approved as Basin Plan amendments, although they have been carefully reviewed for accuracy. They should be considered as a draft work product, to be used for informational purposes only. If you have any comments or corrections concerning these maps, please contact Regional Board staff Dave Woelfel at dwoelfel@waterboards,ca.gov or (951) 782-7960.
