If you're looking for a fight, go seek the Juniata River's muskies and big smallmouths. Purebred muskies are stocked all the way to Mapleton. Focus on long, deep pools, particularly ones that have a good amount of overhead cover. Also try the holes at mouths of larger tributary streams. Muskies gobble jointed surface plugs, but try plastic lizards rigged Texas-style too. The smallmouths thrive throughout the Juniata. Big fish lurk between Duncannon and Mifflintown. Public access points dot this area along Route 322. Focus on the tails of riffles and underwater ledges. Shallow-running Rapalas are a top choice. Flyfishermen prefer Clouser's Deep Minnow.
