The bridge is the dam crossing. The trail goes around the lake and crosses the dam. It winds around through the woods, but never too far from the banks of the lake. Very nice trail.
Ahhh yes, the beautiful ladies of the lake! They look harmless enough until they lure you in with their beautiful smiles and get you under their spell. Then they turn you into a hopelessly lame-for-life shark, right Gramps? ;)
