Brown Bridge Pond seven months after dam removal. The dam was breached on 6 October following drawdown of the lake over the summer. This dam removal is the first in a series of four dam removals in order to return the Boardman River to free-flowing status.

You can see remnants of the dam along the left side of the image. Restoration of the dam area is still ongoing.

This is the first growing season after the removal. Will try to do a series of repeat images to show development of plant community on the exposed bottom land

Zooming in to the stumps along the lower right side, you can see the extensive populations of (now ex-) zebra mussels.
