137-acre lake in Jackson County, Illinois. The lake tops out around 32 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. What the data behind the map says about each species, season by season:
Lake Murphysboro maps at 137 acres behind 5 miles of shoreline. The 3 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 66% of this chart, as modeled. The basin spans about 0.9 mi end to end and 0.6 mi across at its widest. Jackson County claims this one. Its nearest charted neighbour, Kinkaid Lake, is 5 mi to the northwest.
Come spring, look for bluegill tight to the bank in 1 to 6 ft. They move out to 4 to 15 ft in summer and finish the year down in 10 to 25 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 4 ft that scores prime in spring. Best bite is early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (4 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (4 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (4 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (27 ft) | Tiny spoon |
Come spring, look for channel catfish tight to the bank in 3 to 12 ft. Expect a summer slide to 8 to 25 ft, then a winter hold in 10 to 32 ft. Start at Deep basin. It's a deep basin holding about 27 ft of water and rates prime come winter. Prime time lands in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (4 ft) | |
| Summer | 8 to 25 ft | night & dusk | Deep basin (27 ft) | |
| Fall | 10 to 30 ft | dusk | Deep basin (27 ft) | |
| Winter | 10 to 32 ft | midday | Deep basin (27 ft) |
When the water first warms, crappie slide up into 2 to 8 ft. By summer they slide out to 10 to 25 ft, and by winter most fish are in 10 to 32 ft. If you only fish one area, make it Deep basin: a deep basin around 27 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a jig trolled/spider-rigged or a small crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (4 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | Deep basin (27 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Shallow bay flat (4 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 10 to 32 ft | midday | Deep basin (27 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
When the water first warms, flathead catfish slide up into 5 to 20 ft. Summer is an 8 to 30 ft game here, winter a 10 to 32 ft one. Start at Deep basin. It's a deep basin holding about 27 ft of water and rates prime come fall. The feeding windows run after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | night & dusk | open water | |
| Summer | 8 to 30 ft | night & dusk | Deep basin (27 ft) | |
| Fall | 9 to 32 ft | night & dusk | Deep basin (27 ft) | |
| Winter | 10 to 32 ft | midday | Deep basin (27 ft) |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 10 to 32 ft. Start at Shallow bay flat. It's a weed flat holding about 4 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
