INVASIVE SPECIES [ZEBRA MUSSELS] | Rick Dahlstrom

Zebra and quagga mussels are in Long Lake!

Zebra Mussels

Zebra mussels are a well-known invasive species in the Great Lakes region. Together with their cousin the quagga mussel (which can grow a little larger and live in deeper waters, but looks the same), they have spread into inland waters and the Great Lakes since they arrived in Lake St. Clair.

The Zebra mussel population in Long Lake has continued to increase every year since they were first spotted in Long Lake around 2020. Recent observations show no sign of population decline in 2026. Calcium levels in Long and Mickey lakes remain at levels at which Zebra Mussels can reproduce. Ruth Lake calcium levels are lower; as a result, Zebra Mussels are unlikely to flourish in Ruth.

As we have noted in past communications, there is no method to control or eradicate Zebra mussels. However, there are a few things we can do.

  1. Be careful when you are handling or walking around large clusters of these shells. Their edges are sharp and can inflict a skin cut.
  2. If you come upon a large cluster by the shoreline, carefully remove it and get it out of the water. Doing so removes a potential hazard and an unwanted invader from the water.
  3. Avoid transporting them to other water bodies! Please clean your boat before entering and upon exiting any lake. Make sure guests and renters are doing the same. Please use the existing cleaning station at the Charter Township of Long Lake Hall. While Zebra Mussels have already entered our lakes, we can still prevent other invasive species from gaining access.

Thank you for all that you do to maintain the high quality of our lakes. Have a safe and enjoyable Summer!

FEMALES CAN PRODUCE A MILLION EGGS A YEAR!

In 2021 zebra mussels are again reproducing in Long Lake. Each female can produce a million eggs in a year. As you see in our lake they are often found attached to clamshells. If you see Zebra Mussels on rocks, clams, dock stands, or anything else, please immediately remove them from the lake. We should all stay vigilant while enjoying our time in the water.
