Potomac River just S of Mount Vernon Yacht Club

This stretch of the Potomac just south of Mount Vernon Yacht Club is classic snakehead water — shallow, weedy, and full of places for them to hide. Look for pads, matted grass, and laydown wood along the shoreline breaks; snakeheads stack up in this cover to ambush, and they'll hold tight to it even under boat traffic. Because this section is tidal, with the nearest NOAA reference at Marshall Hall about a mile off, water movement really dictates where the fish sit. On high tide, snakeheads push way back into flooded grass and shallow pockets, tough to reach and often uninterested. As the tide starts to fall, they slide out of the skinny stuff toward the drains, points, and current edges — that ebb movement is when the bite really turns on, concentrating fish in predictable ambush lanes.

Shore access is workable — there's mapped parking around 0.37 miles from the water — but a kayak or small boat gives you a real advantage here, letting you work the pad edges and wood at multiple tide stages. A boat ramp is mapped about 0.38 miles away for launching.

Tactics stay simple: walk a weedless frog or buzzbait right over the mats and grass, working pauses around any holes. Chatterbaits and weedless soft plastics fished along drop-offs and current seams cover the falling-tide bite well. Spool up 40-65 lb braid — you'll need it to horse fish out of cover once they eat.
