Hollow Body Frog Fishing on Pymatuning Reservoir
Pymatuning Reservoir · Pennsylvania / Ohio · Northeast
Pymatuning is a large, shallow impoundment — average depth hovers around 10–12 feet — built in 1934 on the Shenango River watershed, making it one of the oldest and largest man-made lakes in the Northeast. The basin holds a mixed bag of largemouth bass, walleye, muskellunge, crappie, and perch, but its largemouth fishery is built on submerged timber fields, expansive weed flats, and flooded brushy shoreline cover. Water clarity tends toward stained or slightly turbid, especially on the Pennsylvania side, which pushes bass tight to visible structure and rewards high-contrast presentations over finesse.
A soft, hollow body with two upturned hooks that rides over surface vegetation completely weedless. Work it across mats, let it fall into pockets, and work it around pad edges. When a bass grabs it from below, the soft body collapses and the hooks drive home. Big-fish technique — frog fishing consistently produces 4+ pound fish.

Seasonal Tactics on Pymatuning Reservoir
Lake: Largemouth push into the flooded brush and emerging milfoil flats in the 4–6 ft range as water temperatures climb through the mid-50s into the low 60s, typically late April through mid-May. The northern Pennsylvania shoreline shallows warm first and hold the earliest pre-spawn concentrations.
Hollow Body Frog: Fish the edges of sparse early grass and around pads as water warms above 60°F.
Lake: Post-spawn bass scatter to deeper weed edges and submerged timber lines in 8–14 ft of water as surface temps push into the upper 70s. Milfoil and coontail mat up through July and August, creating punching and frog opportunities along the main basin flats.
Hollow Body Frog: Prime season. Work across matted grass and punch into pockets. Midday bite can be excellent under mats.
Lake: Shad and perch schools drive bass into aggressive feeding windows from late September through October. Largemouth stack near channel edges and the deeper weed lines in 10–16 ft, responding well to swimbait and crankbait presentations targeting transitional depth breaks.
Hollow Body Frog: Fish open pockets in dying grass. Work slowly as fish become less aggressive.
Lake: Ice cover is common from late December through February on Pymatuning, and ice-fishing pressure for perch and walleye is heavy. Open-water bass fishing essentially shuts down; any late-fall window before hard freeze finds bass lethargic in 12–18 ft near submerged timber, requiring slow-dragged jigs to generate bites.
Hollow Body Frog: Not applicable — bass leave shallow vegetation in cold water.
Best Conditions
Thick grass mats, lily pads, surface vegetation, shallow water in summer, post-spawn through fall, morning and evening
Wait on the hookset. After the explosion, lower the rod tip slightly and wait until you feel pressure before sweeping hard. Premature hooksets cost half your fish.
