Search for Starry Stonewort

Join others around the state to search for one of Minnesota's newest aquatic invasive species, starry stonewort (and other invaders) on August 18th. Starry stonewort is an invasive algae that was first found in Lake Koronis in 2015 and has since spread to 11 Minnesota lakes (learn more about starry stonewort here).

Help is needed to search other lakes to better understand its distribution in Minnesota. You do not need to live on a lake to participate, and lots of volunteers are needed to visit lakes that may not have residents searching. No experience necessary! Learn more and register here!




Also, on Aug 2nd & Oct. 10th, 2017, we had Blue Water Science come out and search for Starry Stonewort at the Bob's Bay landing area, Hwy 24 and the Black Pool landing area. They did not detect any Starry Stonewort. Below are two videos they took of the underwater view.
