When we think of lake critters, we often think of fish, frogs, turtles, and plants. However, did you know there is an entire world within each lake that is virtually invisible? Join us for part two of this series to learn about even more critters that play vital roles in lakes that are “hidden” from most eyes. And don’t worry – you didn’t have to see part one to attend part two! Donations appreciated. Held at Presque Isle Community Library.
