581-acre lake near Chester. The lake tops out around 30 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The season-by-season read for each species follows, from the map's own numbers.
Loon Lake maps at 543 acres behind 9.4 miles of shoreline. An index of 2.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. 58% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. The basin spans about 2.3 mi end to end and 1.5 mi across at its widest. Its nearest charted neighbour, Brant Lake, is 8 mi to the east.
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 9 to 30 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 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 (4 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (20 ft) | Texas-rigged 10" worm, Deep-diving crankbait |

When the water first warms, smallmouth bass slide up into 3 to 12 ft. Summer is a 10 to 30 ft game here, winter a 9 to 30 ft one. Start at Main-lake point. It's a point holding about 11 ft of water and rates prime come fall. The feeding windows run early morning and the evening. Keep a drop shot (goby/minnow) or a ned rig rigged through the warm months.

The spring pattern is a shallow one: yellow perch in 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 30 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 4 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (4 ft) | Small jig + curly tail, Perch-pattern micro crank |

Come spring, look for brown bullhead tight to the bank in 2 to 8 ft. Expect a summer slide to 3 to 12 ft, then a winter hold in 10 to 25 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 after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (4 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (4 ft) | |

It's a weed flat holding about 4 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |

In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 9 to 30 ft before dropping to 9 to 30 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 20 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Creek inflow (2 ft) | 1/8 oz jig + minnow, Hair jig |
