123-acre lake near Hubbard County. The lake tops out around 6 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Loon runs 123 acres with 1.9 miles of edge. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 0.7 mi, about 0.4 mi across. The water lies in Hubbard County. The nearest mapped water is Ham, 1 mi to the north.
Spring puts northern pike in skinny water — 2 to 6 ft is the zone. Summer fish stay in 2 to 6 ft, and winter fish hold in 2 to 6 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage 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 | 2 to 6 ft chart-limited; documented 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 6 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 6 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |

Spring puts smallmouth bass in skinny water — 2 to 6 ft is the zone. Summer fish stay in 2 to 6 ft, and winter fish hold in 2 to 6 ft. Fall smallmouth bass concentrate at Main-lake point, a prime-rated point around 6 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.

| Spring | 2 to 6 ft chart-limited; documented 3 to 12 ft | dawn & dusk | Main-lake point (6 ft) | Ned rig, Tube jig |
| Summer | 2 to 6 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (3 ft) | Drop shot (goby/minnow), Ned rig |

| Winter | 2 to 6 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (3 ft) | Blade bait, Hair jig |
In spring, largemouth bass run shallow here, mostly 1 to 6 ft. Summer keeps them at 2 to 6 ft, and they winter in 2 to 6 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft chart-limited; documented 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |

| Winter | 2 to 6 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (3 ft) | Blade bait, Jigging spoon |
When the water first warms, rock bass slide up into 1 to 6 ft. There's no big seasonal slide here — summer means 2 to 6 ft, winter 2 to 6 ft. If you only fish one area, make it Main-lake point: a point around 6 ft that scores prime in summer. In summer the feeding windows fall in the evening. Keep a ned rig (small) or a marabou jig rigged through the warm months.

| Spring | 1 to 6 ft chart-limited; documented 2 to 10 ft | midday & dawn | Main-lake point (6 ft) | 1/16 oz jig + grub, Small inline spinner |

Spring puts crappie in skinny water — 2 to 6 ft is the zone. Summer fish stay in 2 to 6 ft, and winter fish hold in 2 to 6 ft. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 5 ft. Warm-month bites cluster around early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.

The spring pattern is a shallow one: bluegill in 1 to 6 ft. The depth story barely changes: 2 to 6 ft through summer, 2 to 6 ft in winter. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a small sponge spider (fly) or a micro tube jig gets it done.
