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 Mountain Lake: what the data says

220-acre reservoir in Carter County, Oklahoma. The lake tops out around 40 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.

Mountain Lake maps at 218 acres behind 5.1 miles of shoreline. An index of 2.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 46% of the surface — that's where the groceries are. Tip to tip the water measures near 1.3 mi with a 0.7-mi widest point. It sits in Carter County. Lake Jean Neustadt sits 8 mi southeast — the closest neighbouring chart.

Crappie fishing at Mountain Lake

Come spring, look for crappie tight to the bank in 2 to 8 ft. They move out to 10 to 25 ft in summer and finish the year down in 15 to 35 ft. If you only fish one area, make it Deep basin: a deep basin around 40 ft that scores prime in winter. Best bite is early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 8 ft	midday & dawn	Shallow bay flat (1 ft)	1/16 oz jig + tube, Curly-tail grub
Summer	10 to 25 ft	dawn & dusk	Break off the point (24 ft)	Jig trolled/spider-rigged, Small crankbait (trolled)
Fall	8 to 20 ft	dawn	Shallow feeding flat (10 ft)	Jig + minnow combo, Small swimbait (1.5-2")
Winter	15 to 35 ft	midday	Deep basin (40 ft)	Tungsten jig + soft plastic, Tiny jigging spoon

Largemouth Bass fishing at Mountain Lake

When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is an 8 to 20 ft game here, winter a 15 to 35 ft one. Start at Break off the point. It's a drop-off holding about 24 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.

Season	Depth	Best window	Start at	Go-to baits
Spring	2 to 10 ft	dawn & dusk	Shallow bay flat (1 ft)	Spinnerbait, Chatterbait
Summer	8 to 20 ft	dawn & dusk	Break off the point (24 ft)	Texas-rigged 10" worm, Deep-diving crankbait
Fall	4 to 15 ft	midday & dawn	Main-lake point (1 ft)	Squarebill crankbait (shad), Spinnerbait
Winter	15 to 35 ft	midday	Break off the point (24 ft)	Blade bait, Jigging spoon
