Way North Chesapeake Bay Fishing Report (10/30): Susquehanna Flats Slot Rockfish, Garrett Island Catfish & Conowingo Action

Angler casting along the scenic misty Susquehanna River shoreline near Havre de Grace during fall foliage

Crisp late-autumn mornings and dropping water temperatures have kicked off an aggressive late-season feeding frenzy across the northern reaches of the Chesapeake Bay. According to the latest FishTalk Magazine Way North Fishing Report (10/29), the shallow-water striped bass bite across the Susquehanna Flats has rebounded with authority after earlier warm spells, resulting in light-tackle anglers connecting with a solid grade of keeper slot fish. Farther up the river, heavyweight blue catfish and flatheads are packing into deep channel contours and current seams below the dam - offering fast, rod-bending action for both shoreline families and boaters alike.

As baitfish clear out of tidal tributaries and head down the main stem, predatory rockfish and catfish are taking full advantage of the seasonal turnover. Whether you're planning to launch a cartop skiff onto the Flats, wade the rocky current breaks at Susquehanna State Park, or set up camp chairs along the Havre de Grace promenade with the kids, the late-October bite is delivering some of the most consistent action of the entire fall calendar.

Key Takeaways: What’s Biting Across Northern Chesapeake Waters

  • Susquehanna Flats Light-Tackle Slot Stripers: The Flats bite has hit its autumn stride. Anglers working underwater ditches, contour ledges, and deeper grass edges are finding an excellent grade of legal slot rockfish. Light-tackle jigging with 4- to 5-inch soft plastic paddletails on 1/2-oz jigheads has been the top producer, while shallow jerkbaits and topwater walking plugs draw violent reaction strikes during low-light dawn and dusk windows.
  • Deep-Channel Catfish Stacking Around Garrett Island: Dropping water temperatures have pushed trophy-class blue catfish and flatheads off mid-depth flats and into deeper bottom trenches. The deep channel ledges surrounding Garrett Island and the lower Susquehanna River are stacked with fish, with heavy fish-finder bottom rigs baited with fresh cut gizzard shad or eel producing steady double-digit hauls.
  • Conowingo Dam Tailrace Generation Timing: Water release schedules at the Conowingo Hydroelectric Dam continue to dictate the bite below the pool. During periods of active turbine generation, feeding stripers and catfish push tight against the current seams. Anglers casting 3/4-oz jigheads, heavy spoons, and white swimbaits into the moving wash are finding fast strikes around the rocks.
  • Shoreline Perch & Bank Access: White perch are vacating summer shallows and staging in deeper holes (15 to 25 feet) off river points and bridge pilings. Bank anglers fishing from the Havre de Grace City Yacht Basin piers and Millard Tydings Memorial Park are picking up a mix of perch and panfish using simple bottom rigs tipped with bloodworms or nightcrawlers.

Working the open Flats requires dialing in your presentation based on depth and current speed. When drifting across 4- to 8-foot drop-offs near the channel edges, casting a soft plastic paddle tail swimbait paired with a weedless jighead allows you to bounce right above the dying submerged aquatic vegetation where rockfish wait in ambush. During slack tides or calm early mornings, switching over to a shallow-diving jerkbait or a classic surface walker like the Heddon Zara Spook topwater plug triggers explosive topwater boils from roving schoolies.

For catfish enthusiasts targeting the deep cuts around Garrett Island, having gear that can withstand brutal river current and heavy abrasion is paramount. Rigging up stout 7- to 8-foot medium-heavy casting rods with braided main line and heavy-duty circle hooks on sliding sinker rigs ensures clean corner-of-the-mouth hooksets when a 30-pound blue cat picks up your cut bait in 30 feet of water. If you are braving the cold wind on the riverbank, staying dry with layered thermal gear from Simms outerwear and waders will keep you out on the water long after uninsulated anglers pack it in.

Why This Matters for Maryland Families

Late fall along the lower Susquehanna offers one of the most accessible and rewarding outdoor experiences in Harford and Cecil counties. Summer jet-ski traffic and crowded boat ramps have disappeared, leaving riverfront parks peaceful and easy to navigate. If you have kids who get fidgety waiting hours for finicky summer fish to bite, the northern river's invasive blue catfish bite provides near-instant rod action. A simple setup with a lawn chair, a bell clamped to your rod tip, and a chunk of bait can produce arm-tiring battles with 10- to 20-pound fish within casting distance of public park benches.

Finally, taking the family out to harvest blue catfish is an exceptional conservation lesson. Blue catfish are apex predators that consume vast amounts of native crabs, perch, and baby rockfish throughout the watershed. By taking home a cooler full of blue cats, families help protect the Upper Bay ecosystem while stocking their home freezer with dozens of mild, delicious, flaky white fillets for easy autumn fish tacos and chowders.

Baltimore Mom Tip: 3 Secrets for a Smooth Susquehanna Day Trip

  1. Check the Conowingo Generation Schedule Before Leaving Home: Water levels and currents below the dam change dramatically when the floodgates or hydroelectric turbines open. Call the official Conowingo Dam generation hotline (888-457-4076) before packing the car. Fishing near the dam rocks is best approached on low or stabilizing water for shoreline safety.
  2. Family-Friendly Bank Fishing at Susquehanna State Park: If you're fishing with younger children, avoid the steep boulder fields directly below the dam. Instead, head to the Lapidum boat ramp area within Susquehanna State Park or the paved promenade at Millard Tydings Memorial Park in Havre de Grace. Both locations provide level ground, restrooms, easy parking, and deep-water casting access.
  3. Bundle with a 3-Layer System: River valleys channel cold autumn winds directly across the water. Even if inland temperatures reach 55°F, it will still feel ten degrees colder along the open riverbank. Dress kids in moisture-wicking base layers, an insulated mid-layer, and a wind-blocking shell - and pack a heavy thermos of hot cocoa to keep spirits high between bites!
