2,538-acre lake near Princeton. 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.
The outline encloses 2,537 acres, worked by 31.3 miles of shoreline, with 30 islands in the mix. With a shoreline index of 4.4, this water is all arms and coves — edge habitat well beyond its acreage. Roughly 74% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 4.1 mi end to end and 2.7 mi across at its widest. Washington County claims this one. If the bite dies, Crawford Lake is 7 mi to the south.
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 15 to 35 ft. Start at Shallow bay flat. It's a weed flat holding about 5 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (5 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Sharp break (13 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Secondary point (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | Sharp break (13 ft) | Blade bait, Jigging spoon |
When the water first warms, smallmouth bass slide up into 3 to 12 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 12 to 40 ft. If you only fish one area, make it Sharp break: a drop-off around 13 ft that scores prime in winter. In summer the feeding windows fall in early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Secondary point (5 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Sharp break (13 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Sharp break (13 ft) | Jerkbait, Blade bait |
| Winter | 12 to 40 ft | midday | Sharp break (13 ft) | Blade bait, Hair jig |
Early season white perch use the shallows, holding in 4 to 15 ft. Summer is a 15 to 40 ft game here, winter a 12 to 40 ft one. The chart's best answer is Creek inflow — inflow / creek mouth, 6 ft, prime for spring. Best bite is early morning. Tie on a small spinner rig drifted or a 1/8 oz jigging spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Creek inflow (6 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 15 to 40 ft | dawn | Deep basin (39 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 12 to 40 ft | midday | Deep basin (39 ft) | Jigging spoon (small), Blade bait |
| Winter | 12 to 40 ft | dusk | Deep basin (39 ft) | Small rattle spoon, Tungsten + spikes |
Come spring, look for brown bullhead tight to the bank in 2 to 8 ft. They move out to 3 to 12 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 5 ft that scores prime in spring. Best bite is after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (5 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (5 ft) | |
| Fall | 5 to 15 ft | dusk | Old creek channel (8 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (39 ft) |
Start shallow in spring: chain pickerel sit in 2 to 10 ft that time of year. Summer pushes them deeper, 3 to 15 ft, and winter fish settle into 5 to 18 ft. The spot to know is Shallow bay flat, a weed flat in about 5 ft of water that rates prime for chain pickerel in spring. Warm-month bites cluster around early morning and the evening. Throw a weedless spoon + trailer or a buzzbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Shallow bay flat (5 ft) | Inline spinner (silver), Small spoon (red/white) |
| Summer | 3 to 15 ft | dawn & dusk | Shallow bay flat (5 ft) | Weedless spoon + trailer, Buzzbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (5 ft) | Jerkbait along weed edges, Spinnerbait |
| Winter | 5 to 18 ft | dawn | Shallow bay flat (5 ft) | Jigging spoon (through ice) |
Start shallow in spring: pumpkinseed sit in 1 to 8 ft that time of year. Warm water sends them out to 2 to 10 ft; cold water stacks them in 6 to 18 ft. Top water on the chart: Shallow bay flat, a weed flat in the 5 ft range, prime in spring. Fish it in the evening and early morning and you'll meet the bite. Throw a micro tube or a sponge spider (fly) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (5 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (5 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Shallow bay flat (5 ft) | Tungsten ice jig + plastic, Tiny spoon |
