54-acre reservoir in Oneida County, Wisconsin. The lake tops out around 16 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 54 acres, worked by 2.8 miles of shoreline. That shoreline is heavily fingered (development index 2.7) — bays, points and pockets everywhere, which multiplies the fishable edge. Figure 0.7 mi of water from one end to the other, 0.4 mi at the beam. It sits in Oneida County. If the bite dies, McCabe Lake is 1 mi to the east.
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 5 to 16 ft; cold water stacks them in 5 to 16 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 16 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 16 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for crappie tight to the bank in 2 to 8 ft. They move out to 5 to 16 ft in summer and finish the year down in 5 to 16 ft. If you only fish one area, make it Deep basin: a deep basin around 14 ft that scores prime in winter. Best bite is early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 5 to 16 ft | dawn & dusk | Deep basin (14 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 5 to 16 ft | dawn | Deep basin (14 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 5 to 16 ft | midday | Deep basin (14 ft) | Tungsten jig + soft plastic, Tiny jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. By summer they slide out to 4 to 15 ft, and by winter most fish are in 5 to 16 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 3 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (3 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 5 to 16 ft | midday | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 16 ft | midday | Deep basin (14 ft) | Tungsten ice jig + plastic, Tiny spoon |
The spring pattern is a shallow one: pumpkinseed in 1 to 8 ft. As the season builds they drop to 2 to 10 ft, wintering in 5 to 16 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for the evening and early morning. Summer baits: a micro tube or a sponge spider (fly) gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 5 to 16 ft | dawn | Deep basin (14 ft) | Tungsten ice jig + plastic, Tiny spoon |

Frederick Flowage is about 16 ft (5 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target yellow perch, crappie, bluegill, pumpkinseed on Frederick Flowage. These come from the Wisconsin DNR's per-lake fish listing; where the DNR lists a group (panfish, catfish, trout) the specific species are resolved from Wisconsin's fish distribution by the lake's location, depth and habitat.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Open the map above to see every rated spot for each species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
