* About Invasive Species: Disclaimer: Aquatic invasive species (AIS) records are assigned statuses of "verified", "observed", or "no longer observed" based on AIS Status Guidance. In general, "verified" populations are established and have been verified by a taxonomic expert. Populations with the "observed" status have not been verified by a taxonomic expert or do not have established populations. Populations with the "no longer observed" status include populations where a reproducing population did not establish. Our inventories are not necessarily exhaustive so it is important to report occurrences. To report new discoveries visit: https://dnr.wisconsin.gov/topic/Invasives/report.html. See the Aquatic Invasive Species Guidance for information on how statuses are assigned. Personally identifiable information on data collection forms may be provided to requesters to the extent required by Wisconsin's Open Records Law [ss. 19.31-19.39, Wis. Stats.].

** About Boating Ordinances: Before boating on an unfamiliar Wisconsin waterways check for a sign at the public boat landing to determine if there are local regulations (more restrictive than state law) which may apply on that waterbody. Also be sure to review the document Wisconsin Boating Regulations to learn about statewide regulations. There may be a delay between the time an ordinance is passed and the time it gets into our database. Therefore, the only way to know for sure if a water body has an ordinance in effect is to look for a sign posted at a public boat landing.
