As the nation works to slow the spread of COVID-19, the U.S. Army Corps of Engineers reminds all visitors, volunteers, and employees that a face mask is required to be worn at all Blue Marsh Lake facilities. Masks must always be worn when entering any building including the Visitor Center, comfort stations, and administration buildings. Masks must be worn outdoors on Blue Marsh Lake property and recreation areas if physical distancing cannot be met, such as when hiking on trails or visiting sites that may be popular or crowded.
