How to fish Pentagon Lagoon
Pentagon Lagoon is a quiet, non-tidal lake, so you're not chasing a moving current here—you're chasing light and cover. Snakehead in this lagoon relate hard to whatever vegetation and wood they can find, sitting tight to pads, matted grass edges, and any laydown or brush pile that breaks up open water. Because the level stays steady day to day, the fish settle into predictable ambush spots and don't get pushed around by tide swings, so once you find a good mat or grass line, it's worth returning to.
Since there's no tide to plan around, focus on low light—first hour of daylight and the last hour before dark are prime, especially on wind-blown cover where baitfish get pushed into the vegetation. Midday in summer heat, look for shade lines along grass edges or under overhanging brush where snakehead slide to cool off and ambush.
Shore access is solid, with parking mapped nearby, closest about 0.21 mi from the water, so you can walk in and work the bank without much hassle. If you'd rather cover more water, there's a boat ramp mapped nearby too, roughly 0.25 mi off, good for a kayak or small boat to slip along the grass lines quietly.
Rig up with 40-65 lb braid and go weedless—topwater frogs and buzzbaits worked slow over matted vegetation draw vicious strikes, while chatterbaits and weedless soft plastics punched into pockets in the grass close the deal when they won't commit on top.
