Hollow Body Frog Fishing on Fox Chain O' Lakes
Fox Chain O' Lakes · Illinois · Midwest
The Fox Chain O' Lakes is a glacial lake system strung together by the Fox River and natural channels in Lake County, Illinois, just south of the Wisconsin border. Water clarity tends toward stained to moderately clear depending on the individual lake and season, with abundant aquatic vegetation — milfoil, coontail, and lily pad beds — defining the primary bass habitat. The system holds largemouth, smallmouth, and northern pike, with largemouth dominating the shallow weedy bays and smallmouth concentrating in cleaner-bottomed areas with firmer substrate near current transitions.
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 Fox Chain O' Lakes
Lake: Largemouth push into lily pad flats and emergent reed edges as water temperatures climb through the low 60s, typically late April into May. Spawning fish use 2–5 ft of water over sand and gravel near vegetation transitions — swimbaits and jerkbaits draw strikes during the pre-spawn; Texas-rigged soft plastics excel once fish are on beds.
Hollow Body Frog: Fish the edges of sparse early grass and around pads as water warms above 60°F.
Lake: Thick milfoil and coontail mats form by mid-July and concentrate largemouth beneath and along the edges in 4–8 ft; frogging and punch-rigging become the most productive approaches. Smallmouth migrate toward rocky riprap stretches along the Fox River channel and the harder-bottomed flats of Bluff Lake and Pistakee Bay, where drop shots and tube baits outproduce anything else.
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 become the primary driver of bass movement in September and October; largemouth chase bait along the outside edges of dying vegetation in 6–10 ft. Swimbaits and lipless crankbaits like the Strike King Red Eye Shad in natural shad colors cover water quickly and locate active fish before the weed lines collapse.
Hollow Body Frog: Fish open pockets in dying grass. Work slowly as fish become less aggressive.
Lake: Bass fishing slows dramatically after water temps drop below 45°F, but fish don't disappear — they stack in the deepest available holes and channel bends, mostly 15–20 ft in this relatively shallow system. A finesse approach with a drop shot rigged with a Zoom Finesse Worm on 6 lb fluorocarbon can produce on warmwater discharge areas near the Fox River connection.
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.
