65-acre reservoir near Bonham. Small CCC-built community fishing lake in Bonham State Park. The lake tops out around 19 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The rest of this page walks each species through its year, using the map's own scoring.
Bonham State Park Lake maps at 51 acres behind 1.3 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. About 75% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Tip to tip the water measures near 0.5 mi with a 0.2-mi widest point. It sits in Fannin County. If the bite dies, Lake Bonham is 8 mi to the north.
When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is a 6 to 19 ft game here, winter a 6 to 19 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. 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 (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 |
When the water first warms, channel catfish slide up into 3 to 12 ft. Summer is a 6 to 19 ft game here, winter a 6 to 19 ft one. Start at Deep basin. It's a deep basin holding about 16 ft of water and rates prime come winter. The feeding windows run after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| 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) |
Come spring, look for crappie tight to the bank in 2 to 8 ft. They move out to 6 to 19 ft in summer and finish the year down in 6 to 19 ft. If you only fish one area, make it Deep basin: a deep basin around 16 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 (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 6 to 19 ft | dawn & dusk | Break off the point (9 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 6 to 19 ft | dawn | Break off the point (9 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. By summer they slide out to 4 to 15 ft, and by winter most fish are in 6 to 19 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| 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 |
