Hollow Body Frog Fishing on Carlyle Lake
Carlyle Lake · Illinois · Midwest
Carlyle Lake sits in Clinton County in Southern Illinois, impounded on the Kaskaskia River in the 1960s, covering approximately 26,000 surface acres when full. The fishery blends wide-open main-lake flats with flooded timber, laydown-lined creek arms, riprap causeways, and shallow grass pockets — a structural mix that supports a healthy largemouth population with occasional quality smallmouth in cleaner water near the dam. Clarity runs stained to slightly murky most of the year, improving near the dam pool and turning coffee-colored in the upper creek arms after significant rainfall.
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 Carlyle Lake
Lake: Pre-spawn largemouth push into shallow creek arms and flooded timber flats as water temps climb through the mid-50s into the low 60s, staging on the first hard bottom or gravel transitions they can find. A 3/8 oz War Eagle spinnerbait or a swimbait crawled along the 5–8 ft transition is a consistent producer before fish move up to beds in back pockets and timber edges.
Hollow Body Frog: Fish the edges of sparse early grass and around pads as water warms above 60°F.
Lake: Post-spawn fish scatter but consolidate again around main-lake brush piles in 15–22 ft once the thermocline locks in — local anglers drop marker buoys on specific piles and fish them vertically with a drop shot or a 3/4 oz football jig. Surface schooling activity over the main lake flats picks up by late August when shad start balling up ahead of the fall transition.
Hollow Body Frog: Prime season. Work across matted grass and punch into pockets. Midday bite can be excellent under mats.
Lake: Shad migration into the upper creek arms pulls largemouth shallow through October, with walking baits like the Heddon Super Spook Jr. and 3/8 oz lipless crankbaits producing aggressive reaction strikes in 3–8 ft of water. Fish typically follow the baitfish tightly, so mobility — running creek arm to creek arm until active fish are located — outperforms anchoring on a single spot.
Hollow Body Frog: Fish open pockets in dying grass. Work slowly as fish become less aggressive.
Lake: Carlyle's bass fishing slows considerably in January and February, but the deeper timber edges and channel swings in 18–25 ft hold suspended fish catchable on a blade bait like a 1/2 oz Silver Buddy worked with a lift-drop cadence. Water temps in the upper teens Celsius aren't uncommon near the dam pool, and those fish require a slower, more deliberate approach than most visitors offer.
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.
