Jesse W. Thornton Lake Depth Map & Fishing Spots (KY)

Hatch outlook

Willow fly (summer mayfly)Active window

Typical here: Apr 1 – Oct 31 · recurring broods all summer — the heart of it is June–July, famously around July 4th on the Tennessee River lakes; any one hatch lasts days to ~3 weeks

dunhatches at dusk — clouds of bugs just before dark, continuing into the night — after hatching they fly to shoreline foliage — trees near lighted docks get covered; the feeding zone is the water under bug-loaded overhanging bushes and willows
spinnerthe following days: mating, egg drop and spent flies falling from the overhangs — the bream bite under the bushes runs as long as the bugs do

A two-level event: bream stack under the bug trees, and the big bass stack under the bream. Fish the same bushes twice — small for bream, big for the bass just outside them.

Crickets or small poppers under a float tight to the bug-covered bushes for bream; beetle spins and hair jigs just under the surface; for the bass, run a bluegill-pattern topwater or squarebill down the outside edge of the overhangs.

The event happens over under and just outside overhanging willows and bushes on steep banks; trees near lighted docks after dark

Fishing Jesse W. Thornton Lake: what the data says

43-acre lake in Warren County, Kentucky. The lake tops out around 8 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here is how the season plays out for each species, straight from the data behind the map.

The chart traces 1.7 miles of shoreline here. An index of 2.2 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. The basin spans about 0.4 mi end to end and 0.3 mi across at its widest. Warren County claims this one. If the bite dies, West Fork Drakes Creek Reservoir is 15 mi to the southwest.
