160.8-acre reservoir near LeRoy. The lake tops out around 24 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
The drawn water covers 153 acres wrapped in 4.5 miles of bank. An index of 2.6 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 75% of this chart. End to end it runs roughly 1.2 mi, about 0.5 mi across. McLean County claims this one. If the bite dies, Lake Clinton is 17 mi to the south.
Spring puts saugeye in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 8 to 22 ft; cold water stacks them in 7 to 24 ft. Break off the point is the standout, a drop-off at roughly 17 ft, rated prime for fall saugeye. Plan around the evening and early morning in the warm months. A crawler harness (shallow) or a jig + crawler covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + twister tail, Blade bait |
| Summer | 8 to 22 ft | dusk & dawn | Main-lake point (8 ft) | Crawler harness (shallow), Jig + crawler |
| Fall | 7 to 24 ft chart-limited; documented 8 to 28 ft | dusk & dawn | Break off the point (17 ft) | Blade bait, Jigging rap |
| Winter | 7 to 24 ft chart-limited; documented 12 to 30 ft | dusk & dawn | Deep basin (24 ft) | Jigging spoon + minnow head, Blade bait |
Early season channel catfish use the shallows, holding in 3 to 12 ft. Expect a summer slide to 7 to 24 ft, then a winter hold in 7 to 24 ft. Put Deep basin first on the milk run — a deep basin near 24 ft that grades prime for winter. In summer the feeding windows fall in after dark and the evening.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (6 ft) | |
| Summer | 7 to 24 ft chart-limited; documented 8 to 25 ft | night & dusk | Deep basin (24 ft) | |

Spring crappie on Dawson Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 7 to 24 ft, and by winter most fish are in 7 to 24 ft. The chart's best answer is Deep basin — deep basin, 24 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a jig trolled/spider-rigged or a small crankbait (trolled).

| 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 | 7 to 24 ft chart-limited; documented 10 to 25 ft | dawn & dusk | Break off the point (17 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | Break off the point (17 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 7 to 24 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (24 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 7 to 24 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.

Dawson Lake is about 24 ft (7 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target saugeye, channel catfish, crappie, largemouth bass on Dawson Lake.
Break off the point is the top-rated area: a drop-off in about 17 ft of water that rates prime for saugeye in fall. Open the map above to see every rated spot for each species and season.
For saugeye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
