Hatch outlook

Fall shad migrationActive window

Typical here: Sep 1 – Dec 15 · upper ends and stained creeks turn on first, the main lake follows; Deep-South creeks hold bait into December

adultall day, best mid-afternoon as the sun warms the bait — the rare pattern where you can sleep in — follow the bait, not the structure: gulls, herons and egrets diving or stacked in a creek mean the shad (and the bass) are there — run and gun until you find flickering bait or surface activity

Concentrates hard but unevenly — whole stretches go empty while one creek loads up. The birds are the map.

Creek-arm run-and-gun: lipless crankbait and squarebill through the flats and ditches, walking topwater over surface schools, a 3/8 oz spinnerbait around isolated cover along the creek channel. Downsize to match the young-of-year shad; jerkbaits are the sleeper.

The event happens over backs of creek arms, pockets and ditches, secondary points on the way in, and main-lake flats where the bait balls roam

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 Blue Cat Lake: what the data says

80-acre lake near Williamsport. TWRA Williamsport family fishing lake; surveyed max 19 ft. The lake tops out around 19 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here's the year, species by species, as the scoring engine sees it.

Traced from the shoreline, Blue Cat Lake runs 83 acres with 2.5 miles of edge. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. The shallow band under 15 ft claims about 83% of the surface on the model — that's where the groceries are. End to end it runs roughly 0.7 mi, about 0.5 mi across. The water lies in Maury County. The nearest mapped water is Whippoorwill Lake, 0 mi to the north.

Largemouth Bass fishing at Blue Cat Lake

Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 6 to 19 ft, wintering in 6 to 19 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 10 ft	dawn & dusk	Shallow bay flat (3 ft)	Spinnerbait, Chatterbait
Summer	6 to 19 ft	dawn & dusk	Break off the point (9 ft)	Texas-rigged 10" worm, Deep-diving crankbait
Fall	4 to 15 ft	midday & dawn	Main-lake point (8 ft)	Squarebill crankbait (shad), Spinnerbait
Winter	6 to 19 ft	midday	Break off the point (9 ft)	Blade bait, Jigging spoon

Bluegill fishing at Blue Cat Lake

Start shallow in spring: bluegill sit in 1 to 6 ft that time of year. Summer pushes them deeper, 4 to 15 ft, and winter fish settle into 6 to 19 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for bluegill in spring. Warm-month bites cluster around early morning and the evening. Throw a small sponge spider (fly) or a micro tube jig until the fish tell you otherwise.

Season	Depth	Best window	Start at	Go-to baits
Spring	1 to 6 ft	midday & dusk	Shallow bay flat (3 ft)	1/32 oz jig + micro plastic, Tiny popper (evenings)
Summer	4 to 15 ft	dawn & dusk	Shallow bay flat (3 ft)	Small sponge spider (fly), Micro tube jig
Fall	6 to 18 ft	midday	Break off the point (9 ft)	Micro jig + waxworm, Small spoon tipped
Winter	6 to 19 ft	midday	Deep basin (16 ft)	Tiny spoon

Channel Catfish fishing at Blue Cat Lake

Spring puts channel catfish in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 6 to 19 ft, wintering in 6 to 19 ft. Winter channel catfish concentrate at Deep basin, a prime-rated deep basin around 16 ft. Warm-month bites cluster around after dark and the evening.

Season	Depth	Best window	Start at
Spring	3 to 12 ft	dusk	Shallow bay flat (3 ft)
Summer	6 to 19 ft	night & dusk	Deep basin (16 ft)
Fall	6 to 19 ft	dusk	Deep basin (16 ft)
Winter	6 to 19 ft	midday	Deep basin (16 ft)

Blue Catfish fishing at Blue Cat Lake

It's a deep basin holding about 16 ft of water and rates prime come winter. The feeding windows run early morning and the evening.

Season	Depth	Best window	Start at
Spring	4 to 19 ft	dusk	Break off the point (9 ft)
Summer	5 to 19 ft	dawn & dusk	Deep basin (16 ft)

White Bass & Hybrids fishing at Blue Cat Lake

In spring, white bass & hybrids run shallow here, mostly 3 to 15 ft. Summer pushes them deeper, 6 to 19 ft, and winter fish settle into 6 to 19 ft. Main-lake point is the standout, a point at roughly 8 ft, rated prime for fall white bass & hybrids. Time it for early morning and the evening. You won't need more than a jigging spoon or a topwater (when schooling) most summer days.

Season	Depth	Best window	Start at	Go-to baits
Spring	3 to 15 ft	midday & dawn	Main-lake point (8 ft)	Rooster tail / inline spinner, Curly-tail jig (white/chartreuse)
