Information about Aquatic Invasive Species in Oregon

The Online Atlas of Oregon Lakes (OAOL) is committed to helping reduce the risk of the introduction and spread of Aquatic Invasive Species (AIS).  We believe this can be accomplished through a public that is well informed on how Clean-Drain-Dry and other practices can reduce the spread of AIS, how to keep an eye out for AIS, how to report suspicious species, and the waterbodies that are infested with AIS. Funding for presenting AIS distribution data and other AIS information on the Online Atlas of Oregon Lakes was provided through the Oregon State Marine Board’s AIS Prevention Program.  Links to a wealth of information about AIS are provided below.
