Antietam Creek (East & West Branches)

Slow, winding meadow-style limestone streams in southern Franklin County that drain south toward the Potomac River rather than the Susquehanna. Highly mineralized water with limestone-spring inputs.

Bank-fish where possible; wading the soft meadow channels muddies the run.

Sulphurs, olives, midges, scuds, sowbugs, caddis, and terrestrials are the right starting box.

Verify access, posted reaches, and current PFBC regulations before planning a trip.
