Scientists study invasive Northern snakeheads in Philadelphia-area waters
Biologists with Pennsylvania's fish commission are investigating the ecological impact and contamination levels of invasive Northern snakeheads in Phiโฆ
Documented northern snakehead water in Delaware County, Pennsylvania. Lower Delaware drainage. 5 USGS specimen records (2011โ2023); status: established. Location verified from the USGS Nonindigenous Aquatic Species database.
Darby Creek is classic snakehead water โ a tidal system where fish tuck into the pockets and edges rather than roam open water. Look for them holding tight to pads, matted grass, and downed wood along the banks, especially where current breaks against structure. Snakeheads here ambush from cover, so any seam between thick vegetation and slightly deeper water is worth working slowly.
Because Darby Creek is tidal, with the nearest reference at Wanamaker Bridge, timing matters as much as location. On the high water, fish push shallow into flooded grass and brush, tough to reach but often aggressive if you can get a bait in front of them. As the tide starts to fall, snakeheads slide off that cover toward the drains and current edges, and this ebb stage is when the bite really turns on โ moving water concentrates baitfish and pulls predators into feeding mode.
Shore access is solid, with parking mapped as close as roughly 0.05 mi from the water, making it easy to slip in and fish likely pockets on foot. For those wanting to cover more skinny water, a boat ramp about 0.34 mi away gives kayak and small boat anglers a way to reach quieter backwaters.
Go-to tactics: weedless topwater frogs and buzzbaits worked over matted cover, chatterbaits along edges, and weedless soft plastics punched into thicker grass. Spool up with 40-65 lb braid to horse fish out of snags once hooked.

Coordinates are approximate, for finding the general area. Snakehead is an invasive species โ regulations on catching, keeping, transporting and killing it vary by state and change often. Never move a live snakehead between waters. Always confirm current rules with your state wildlife agency before you fish.
