49-acre lake near Marshall County. The lake tops out around 15 ft. The depth chart comes from Minnesota Department of Natural Resources bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
On the chart, Unnamed (Florian Pk Res.) draws 49 acres inside 2.4 miles of shoreline. That shoreline is heavily fingered (development index 2.4) — bays, points and pockets everywhere, which multiplies the fishable edge. Tip to tip the water measures near 0.8 mi with a 0.3-mi widest point. The water lies in Marshall County. Closest neighbour on DepthScout: Bronson, 20 mi north of here.
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 5 to 15 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 5 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 8 ft | midday & dawn | Shallow bay flat (5 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 5 to 15 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (5 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 5 to 15 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (5 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (5 ft) | Tip-ups, Large jigging spoon |
When the water first warms, rock bass slide up into 2 to 10 ft. By summer they slide out to 4 to 15 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Secondary point: a point around 5 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.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (2 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 4 to 15 ft chart-limited; documented 5 to 20 ft | dusk | Secondary point (5 ft) | Ned rig (small), Marabou jig |

| Winter | 5 to 15 ft chart-limited; documented 12 to 30 ft | midday | Deep basin (15 ft) | Tungsten jig + plastic, Small spoon + spike |
Spring puts crappie in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 5 to 15 ft, wintering in 5 to 15 ft. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 15 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.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (5 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 5 to 15 ft chart-limited; documented 10 to 25 ft | dawn & dusk | Shallow bay flat (5 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |

The spring pattern is a shallow one: bluegill in 1 to 6 ft. As the season builds they drop to 4 to 15 ft, wintering in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 5 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.

When the water first warms, pumpkinseed slide up into 1 to 8 ft. By summer they slide out to 2 to 10 ft, and by winter most fish are in 5 to 15 ft.

In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 5 to 15 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 5 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.
