Context and History…
Eighty-six years ago, the present day concrete Rapidan Mill dam was constructed in front of an earlier log dam, perhaps all or portions of which date back to 1772. Whenever exactly that earliest structure was completed, approximiately 500-1000 miles (depending on metrics used) of upstream habitat for American shad and other anadromous fish was instantly cut off. It’s unlikely that the Virginia hydro-entrepreneurs likely celebrating that first day of operation in a bedrock outcrop of what would later become Waugh’s Ford had any idea that they had just built a structure that blocked more upstream fishery than possibly any ever constructed in the Cheseapeake Bay watershed of what four years later would become the United States of America.
Also interesting is that six years later, the British would stretch a seine across the Schuylkill to stop Shad from reaching George Washington’s army at Valley Forge in the Spring of 1778. It wasn’t successful, according to Continental Soldier Nathan Hale – an uncommonly early run of the Shad saved Washington and his army – and our nation.
