Although the waters of the Great Falls/Potomac River

Although the waters of the Great Falls/Potomac River Gorge in Washington, D.C. and Maryland may appear calm on the surface, Joint Base Myer-Henderson Hall officials warn that the waters contain strong currents and jagged rocks. Since 2001, two dozen people have lost their lives — including a Joint Base Myer-Henderson Hall-based Soldier — in the park’s waters. JBM-HH officials are reminding service members that aquatic activities in certain portions of the Great Falls area are not only off limits under a Military District of Washington directive, but are also illegal.
