Invasive Watermilfoil Found on Lake Cadillac

Lake Cadillac is dealing with an unusually large invasion of Eurasian watermilfoil.

The invasive species has taken over 160 acres of the lake, the largest invasion since 2010.

The city of Cadillac partnered with Restorative Lake Sciences out of Spring Lake to survey and contain the invasive species.

Watermilfoil can grow quickly, and factors like an extended dry period and extended sun period can help the seeds grow.

Even though we experienced several of the factors this summer, it was still a surprise to see how much area the watermilfoil covered.

“We were able to make it quite a few years, 12 good years, before this happened again,” said Restorative Lake Sciences Water Resources Director and Owner Dr. Jennifer Lynn Jermalowicz-Jones. “It’s probably not going to be the last time unfortunately. We see this periodically with some lakes.”

Restorative Lake Sciences will be managing the watermilfoil this coming spring.
