AIS Alert: Starry Stonewort Found in Long Lake (Hubbard County)














Just one month ago, the Long Lake Area Association (Hubbard County) Inc provided all Long Lake shoreland property owners a letter highlighting LLAA’s mission which includes education and communication. We also explained in that letter and at the LLAA annual meeting that a professional aquatic vegetation survey is planned for the entire lake every 5 years with 2023 being our next planned survey year.  

On Sunday morning, 8/13/23, during the aquatic vegetation survey, the team from vendor Aquatic Survey Professionals detected an Aquatic Invasive Species (AIS) called Starry Stonewort (SSW) in about a 5 foot diameter bright green patch underwater at a depth of about 10 feet. The SSW was confirmed by a DNR Invasive Species Specialist on 8/14/23.

Actions Underway:

  • The LLAA Ready Response to AIS team is currently working with the DNR Invasive Species Specialist and potential AIS management vendors for treatment and control to prevent further spread.
  • We will also reach out to the UMN Aquatic Invasive Species Research Center (MAISRC) to determine if current and past projects information or a pilot could be helpful.  

Check often for updates on this website ( and the Long Lake Living Facebook page.
