Heavy rains caused flash flooding on Friday that led to a number of closures throughout the park:
The entrance road to Great Falls closed for the day, but was expected to reopen on Saturday.
The visitor center was also expected to reopen on Saturday, but boat operations will not resume until canal conditions upstream are evaluated.
The Gold Mine, Ford Mine and Billy Goat Trails are closed due to high water and severe erosion.
Parking areas and towpath access at Pennyfield Lock, Rileys Lock and Viollettes Lock are closed until damage assessments can be completed and the areas are determined safe for visitor use.
Boat ramps throughout the park are open but will be silt covered as the Potomac River recedes. Towpaths have also been scored in some areas, and downed trees have created unsafe conditions throughout the park.
