15-acre reservoir in Waupaca County, Wisconsin. The lake tops out around 12 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. Below is the species-by-species picture, pulled from the same data the map uses.
Keller Lake maps at 15 acres behind 0.9 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 0.3 mi, about 0.2 mi across. It sits in Waupaca County. Little Lake sits 1 mi east — the closest neighbouring chart.
Early season rainbow trout use the shallows, holding in 3 to 12 ft. Even in summer they hold at 3 to 12 ft; winter keeps them in 2 to 12 ft. Put Shoreline break first on the milk run — a drop-off near 5 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Inline spinner (silver), Small spoon |
| Summer | 3 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 3 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 2 to 12 ft | dawn | Shoreline break (5 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. They don't go far with the seasons — 4 to 12 ft covers summer, 4 to 12 ft covers winter. 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 | 4 to 12 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 12 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 12 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. Through summer count on 4 to 12 ft; the winter hold is 4 to 12 ft. If you only fish one area, make it Shoreline break: a drop-off around 5 ft that scores prime in winter. Best bite is early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 4 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 4 to 12 ft | midday & dawn | Shoreline break (5 ft) | Jerkbait, Blade bait |
| Winter | 4 to 12 ft | midday | Shoreline break (5 ft) | Blade bait, Hair jig |
When the water first warms, largemouth bass slide up into 2 to 10 ft. Summer is a 4 to 12 ft game here, winter a 4 to 12 ft one. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 12 ft | midday | Shoreline break (5 ft) | Blade bait, Jigging spoon |
Come spring, look for crappie tight to the bank in 2 to 8 ft. They move out to 4 to 12 ft in summer and finish the year down in 4 to 12 ft. If you only fish one area, make it Deep basin: a deep basin around 10 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 | 4 to 12 ft | dawn & dusk | Shoreline break (5 ft) | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 4 to 12 ft | dawn | Shoreline break (5 ft) | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 4 to 12 ft | midday | Deep basin (10 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 3 to 12 ft, and by winter most fish are in 4 to 12 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 | 3 to 12 ft | dawn & dusk | Shallow bay flat (3 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 4 to 12 ft | midday | Shoreline break (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 4 to 12 ft | midday | Deep basin (10 ft) | Tungsten ice jig + plastic, Tiny spoon |

Keller Lake is about 12 ft (4 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 rainbow trout, yellow perch, smallmouth bass, largemouth bass, crappie, bluegill on Keller Lake. 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. The interactive chart above rates every spot for each species and season.
For rainbow trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
