Hollow Body Frog Fishing on Monroe Lake
Monroe Lake · Indiana · Midwest
Monroe Lake sits in Monroe and Brown counties in south-central Indiana, impounded by the U.S. Army Corps of Engineers on Salt Creek in 1965. The reservoir features a mix of standing and submerged timber in the upper arms, hard rocky points and bluff-adjacent banks in the mid-lake zones, and a cleaner main-lake basin near the dam — water clarity ranging from moderately stained in the creek arms to surprisingly clear in the lower lake after extended dry periods. Largemouth bass dominate the catch, with a healthy population of spotted bass that most visiting anglers underestimate.
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 Monroe Lake
Lake: Pre-spawn largemouth push into the upper creek arms of the Harrodsburg and Beanblossom arms once water temps climb above 55°F, staging on submerged timber edges in 8–14 ft before moving shallow to gravel and chunk-rock banks to spawn. A 3/8 oz swimbait or slow-rolled Keitech through those timber edges in late March can be one of the most productive windows on the whole lake.
Hollow Body Frog: Fish the edges of sparse early grass and around pads as water warms above 60°F.
Lake: Post-spawn fish scatter to main-lake points and ledges in 15–25 ft as surface temps push into the mid-80s°F; spotted bass school tightly on channel swings in the lower lake while largemouth tend to suspend near shaded bluff banks or tuck into docks along the mid-lake. A drop shot or football jig worked slowly through 18–22 ft accounts for the bulk of quality fish through July and August.
Hollow Body Frog: Prime season. Work across matted grass and punch into pockets. Midday bite can be excellent under mats.
Lake: Shad migrations pull both largemouth and spots into the creek arms and upper coves as water temps fall through the 60s°F in October and November — topwater and squarebill crankbaits around riprap and rocky points can produce fast-action windows at first light before the bite transitions to reaction baits along channel edges.
Hollow Body Frog: Fish open pockets in dying grass. Work slowly as fish become less aggressive.
Lake: Winter fishing on Monroe slows considerably but doesn't shut down; spotted bass in particular hold on main-lake points and channel ledges in 25–35 ft, responding to a drop shot or shaky head fished with near-motionless patience when water temps dip into the upper 40s°F.
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.
