Historically, Polander Lake had an abundance of emergent aquatic plants and provided a good staging area for migrating waterfowl. The area of emergent vegetation declined over the years and has been replaced by submerged vegetation. The changes were caused by sedimentation, wave action, and water velocities that increase turbidity, inhibit the growth of rooted aquatic plants, and decrease the lake’s structural diversity.
