Nestled on the Virginia side of the Potomac River within the Lyndon B. Johnson Memorial Grove, Pentagon Lagoon is a premier inshore fishing destination in the Washington, D.C. metropolitan area. This manmade, sheltered lagoon is fed by the Boundary Channel and offers a quiet, non-tidal environment distinct from the main river's strong currents. Its calm waters, extensive vegetation, and proximity to deep-water structure make it a consistent producer for several sought-after species, providing a reliable fishing option when conditions on the open Potomac are unfavorable.
