On Thursday September 29th Chris Jurek, DNR aquatic invasive species specialist reported to the GLSA that Starry Stonewort was found on West Lake Sylvia at the public access. The access has been posted to notify boaters of this new infestation.
Starry stonewort are grass-like algae that are not native to North America. The plant was first confirmed in Minnesota in Lake Koronis, near Paynesville in Stearns County, in late August of 2015. Since that time, the DNR has reported infestations at Lake Winnibigoshish, Moose Lake , Rice Lake , Upper Red Lake and Cass Lake.
The GLSA Board is meeting with the DNR on Monday to discuss treatment options.
As new information is available we will post it on our website.
You can read more about Starry Stonewort, its impact and how to identify it in the latest Loon Calls and on the Lake Sylvia AIS page.http://lakesylvia.org/AIS
The map below shows the location of the plants (red dots) and the other surveyed locations (yellow).
A crew from Anchor Dock and Lift discovered a Zebra Mussel in about 15ft of water at the southernmost part of the East Lake and attached to weeds. We conducted subsequent searches with the DNR, Blue Water Science and volunteers. We found a single ZM in a second location also on the East Lake. Based on these findings, the DNR has classified Lake Sylvia as infested with Zebra Mussels and has posted a warning sign at the public access.
Steve McComas of Blue Water Science has prepared a report for the GLSA Board of the search efforts and our options for treatment. After consulting with Steve and Chris Jurek (Aquatic Invasive Species Specialist ) of the DNR the GLSA board has concluded that there is no viable treatment option for our infestation that would allow us to eradicate Zebra Mussels in Lake Sylvia.
