160-acre lake in Oneida County, Wisconsin. The lake tops out around 25 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Franklin Lake runs 160 acres with 2.5 miles of edge — one island included. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. 77% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.7 mi with a 0.6-mi widest point. You'll find it in Oneida County. Closest neighbour on DepthScout: Torpy Lake, 1 mi northeast of here.
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is an 8 to 25 ft game here, winter an 8 to 25 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| 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 | 8 to 25 ft | dawn | Deep basin (24 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 25 ft | midday | Deep basin (24 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 25 ft | midday & dawn | Deep basin (24 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (15 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: muskellunge sit in 3 to 12 ft that time of year. Warm water sends them out to 8 to 25 ft; cold water stacks them in 8 to 25 ft. Top water on the chart: Break off the point, a drop-off in the 15 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a double-10 bucktail or a topwater (walk-the-dog / creeper) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk | Shallow bay flat (3 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Break off the point (15 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 7 to 25 ft | midday & dusk | Break off the point (15 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 8 to 25 ft | midday | Deep basin (24 ft) | Large rubber, crawled slow |
In spring, smallmouth bass run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 8 to 25 ft for winter. Winter smallmouth bass concentrate at Break off the point, a prime-rated drop-off around 15 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 8 to 25 ft | dawn & dusk | Break off the point (15 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Break off the point (15 ft) | Jerkbait, Blade bait |

Spring puts largemouth bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 8 to 25 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring largemouth bass. Plan around early morning and the evening in the warm months. A texas-rigged 10" worm or a deep-diving crankbait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (15 ft) | Texas-rigged 10" worm, Deep-diving crankbait |

In spring, crappie run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 10 to 25 ft before dropping to 8 to 25 ft for winter. Winter crappie concentrate at Deep basin, a prime-rated deep basin around 24 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a jig trolled/spider-rigged or a small crankbait (trolled) most summer days.
