151-acre lake in Vilas County, Wisconsin. The lake tops out around 19 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Little John Lake draws 153 acres inside 2.9 miles of shoreline. The shoreline is moderately structured (index 1.7) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 88% of this chart, as modeled. Call it 0.8 mi long by 0.5 mi wide at the broadest reach. You'll find it in Vilas County. Closest neighbour on DepthScout: Little John Junior Lake, 1 mi southeast of here.
Spring puts rainbow trout in skinny water — 5 to 19 ft is the zone. Summer fish stay in 5 to 19 ft, and winter fish hold in 4 to 19 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 9 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 19 ft | dawn & dusk | Break off the point (9 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 5 to 19 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 19 ft | dawn | Break off the point (9 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for walleye tight to the bank in 4 to 15 ft. Expect a summer slide to 6 to 19 ft, then a winter hold in 6 to 19 ft. Start at Break off the point. It's a drop-off holding about 9 ft of water and rates prime come fall. Prime time lands in the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 19 ft | dusk & dawn | Break off the point (9 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 19 ft | dusk & night | Break off the point (9 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 19 ft | dusk & dawn | Deep basin (16 ft) | Jigging spoon + minnow head, Rattle bait |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Warm water sends them out to 6 to 19 ft; cold water stacks them in 5 to 15 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 the evening and you'll meet the bite. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.
| 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 | 6 to 19 ft | dawn & dusk | Break off the point (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (9 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 |
In spring, muskellunge run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 6 to 19 ft before dropping to 6 to 19 ft for winter. Fall muskellunge concentrate at Break off the point, a prime-rated drop-off around 9 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a double-10 bucktail or a topwater (walk-the-dog / creeper) most summer days.
| 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 | 6 to 19 ft | dusk & dawn | Main-lake point (8 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 5 to 19 ft | midday & dusk | Break off the point (9 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 6 to 19 ft | midday | Deep basin (16 ft) | Large rubber, crawled slow |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 6 to 19 ft; cold water stacks them in 6 to 19 ft. Top water on the chart: Main-lake point, a point in the 8 ft range, prime in fall. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 6 to 19 ft | dawn & dusk | Break off the point (9 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 19 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 6 to 19 ft | midday | Break off the point (9 ft) | Blade bait, Hair jig |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 6 to 19 ft before dropping to 6 to 19 ft for winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for largemouth bass in spring. Plan around early morning and the evening in the warm months. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 6 to 19 ft | dawn & dusk | Break off the point (9 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 19 ft | midday | Break off the point (9 ft) | Blade bait, Jigging spoon |
