35,000-acre reservoir near Grenada. The largest lake wholly in Mississippi and its most famous crappie water. A USACE flood-control lake on the Yalobusha and Skuna known nationwide for magnum slab crappie. The lake tops out around 50 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. Below is the species-by-species picture, pulled from the same data the map uses.
Shoreline on the chart totals 104.1 miles, with 2 islands in the mix. An index of 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 63% of the surface on the model — that's where the groceries are. End to end it runs roughly 15.1 mi, about 9.3 mi across. You'll find it in Grenada County. The nearest mapped water is Texas Lake, 10 mi to the northwest.
The spring pattern is a shallow one: crappie in 2 to 8 ft. Midsummer fish sit out in 10 to 25 ft before dropping to 15 to 35 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 6 ft of water that rates prime for crappie in spring. Plan around early morning and the evening in the warm months. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Break off the point (23 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Sharp break (19 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 15 to 35 ft | midday | Break off the point (23 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 15 to 35 ft. Top water on the chart: Shallow bay flat, a weed flat in the 6 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Sharp break (19 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (13 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Break off the point (23 ft) | Blade bait, Jigging spoon |
Early season white bass use the shallows, holding in 2 to 12 ft. Expect a summer slide to 8 to 25 ft, then a winter hold in 15 to 40 ft. Put Main-lake point first on the milk run — a point near 13 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a slab spoon or a small topwater (schooling fish) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 12 ft | dawn & dusk | Shoreline point (5 ft) | Curly-tail jig (white), Small lipless crank |
| Summer | 8 to 25 ft | dawn & dusk | Main-lake point (13 ft) | Slab spoon, Small topwater (schooling fish) |
| Fall | 6 to 25 ft | dawn & dusk | Main-lake point (13 ft) | Jigging spoon, Blade bait |
| Winter | 15 to 40 ft | midday | Deep basin (43 ft) | Jigging spoon (deep), Blade bait |
Start shallow in spring: channel catfish sit in 3 to 12 ft that time of year. Warm water sends them out to 8 to 25 ft; cold water stacks them in 20 to 40 ft.
