07/21/2026 - ZEBRA MUSSELS IN BIG SAND
Big Sand Lake Property Owner,
The BSLA Board is reaching out to help all of us better recognize the three highest‑risk aquatic invasive plant species that could seriously affect the health of Big Sand Lake. As we discussed at the annual meeting, now that zebra mussels have been confirmed in the lake, it is even more important to prevent additional AIS from becoming established. Multiple invasive species interacting together can create a multiplying, long‑term impact on water quality and habitat.
Early detection is one of the most effective tools we have. The sooner an invasive plant is identified, the greater the chance that treatment can be successful. We can all contribute simply by staying alert as we boat, fish, swim, or enjoy the shoreline — but to do that, we need to know what to look for.
To support that effort, we’ve attached a short identification flyer for each of the three priority species, including photos and key characteristics:
Please take a few minutes to review these materials and familiarize yourself with these potential invaders. Your awareness truly makes a difference.
If you’d like to learn more, the Minnesota AIS Research Center offers an excellent, free AIS identification guide (PDF) at: https://drive.google.com/file/d/1uathenpxUq2SkBe3ZHKwSVJjTNun7i6Y/view
A printed, bound version is also available through the University of Minnesota Bookstore.
Thank you for helping keep Big Sand Lake healthy and thriving for generations to come.
