‘Lake Invaders: The Fight for Lake Huron’ Aug. 22

Next up in the Great Lakes Maritime Heritage Center’s Sanctuary Cinema Series is “Lake Invaders: The Fight for Lake Huron,” playing on Thursday, Aug. 22.

Doors open at 6:30 p.m., and the film starts at 7 p.m., free and open to the public, at Great Lakes Martime Heritage Center, 500 W. Fletcher St. in Alpena.

In this 2009 film by John Schmit, Lake Huron, one of the five parts comprising the Great Lakes, has been hit with numerous exotic species invasions over the last century.

Each invasion changes the ecosystem in ways that cannot be predicted.

Fish populations have collapsed, the entire food web completely altered, and a multi-million dollar industry has dried up.

Biologists are racing to understand these changes and restore balance to the third-largest lake in the world before the next invader arrives.

Run time is 56 minutes.
