395-acre lake near Lake County. The lake tops out around 30 ft. The depth data here comes from the Minnesota DNR survey of 1976, a decades-old survey (the DNR's original lake-survey map). Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 395 acres of water rimmed by 8 miles of bank. A development index of 2.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. 48% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 1.6 mi, about 0.8 mi across. You'll find it in Lake County. The nearest mapped water is Tanner, 1 mi to the southeast.
Come spring, look for walleye tight to the bank in 4 to 15 ft. Expect a summer slide to 9 to 30 ft, then a winter hold in 9 to 30 ft. Start at Break off the point. It's a drop-off holding about 19 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 (6 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 9 to 30 ft | dusk & dawn | Break off the point (19 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 9 to 30 ft | dusk & night | Break off the point (19 ft) | Jigging rap, Jig + big minnow |
| Winter | 9 to 30 ft | dusk & dawn | Deep basin (30 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 9 to 30 ft. If you only fish one area, make it Back-bay flat: a weed flat around 6 ft that scores prime in spring. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (30 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft | midday | Deep basin (30 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (30 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, muskellunge run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 8 to 25 ft before dropping to 9 to 30 ft for winter. Fall muskellunge concentrate at Break off the point, a prime-rated drop-off around 19 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 | Back-bay flat (6 ft) | Smaller bucktail (#8 blades), 6" glide bait |
| Summer | 8 to 25 ft | dusk & dawn | Secondary point (15 ft) | Double-10 bucktail, Topwater (walk-the-dog / creeper) |
| Fall | 8 to 30 ft | midday & dusk | Break off the point (19 ft) | Big rubber (Bull Dawg style), 10"+ glide bait |
| Winter | 9 to 30 ft | midday | Deep basin (30 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 10 to 30 ft; cold water stacks them in 9 to 30 ft. Top water on the chart: Secondary point, a point in the 15 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 (6 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (19 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Secondary point (15 ft) | Jerkbait, Blade bait |
| Winter | 9 to 30 ft | midday | Break off the point (19 ft) | Blade bait, Hair jig |
Early season rock bass use the shallows, holding in 2 to 10 ft. Summer is a 5 to 20 ft game here, winter a 12 to 30 ft one. The chart's best answer is Main-lake point — point, 6 ft, prime for summer. Best bite is the evening. Tie on a ned rig (small) or a marabou jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Dumbbell Lake Fishing Pier (6 ft) | 1/16 oz jig + grub, Small inline spinner |
