322-acre lake in Kenora District, Ontario. The lake tops out around 112 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. Below is the species-by-species picture, pulled from the same data the map uses.
Holstein Lake maps at 326 acres behind 7 miles of shoreline — 2 islands included. A development index of 2.7 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 39% of the water is 15 ft or less as modeled, the band where the food chain lives. End to end it runs roughly 1.2 mi, about 0.8 mi across. Kenora District claims this one. Bartley Lake sits 1 mi west — the closest neighbouring chart.
Early season lake trout use the shallows, holding in 10 to 40 ft. Summer is a 34 to 112 ft game here, winter a 20 to 80 ft one. The chart's best answer is Deep basin — deep basin, 95 ft, prime for summer. Best bite is early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (28 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 34 to 112 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (95 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (28 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (50 ft) | White tube jig, Airplane jig |
Spring puts cisco (lake herring) in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 40 to 80 ft; cold water stacks them in 20 to 60 ft. Break off the point is the standout, a drop-off at roughly 50 ft, rated prime for winter cisco (lake herring). Plan around early morning in the warm months. A vertical flutter spoon (small) or a drop-shot micro plastic covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | open water | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (95 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Break off the point (50 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 15 to 35 ft. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 6 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Shallow bay flat (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | open water | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | open water | Tungsten jig + spikes, Rattle spoon (small) |
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 8 to 20 ft, then a winter hold in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a texas-rigged 10" worm or a deep-diving crankbait and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (6 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Shallow bay flat (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 15 to 35 ft | midday | open water | Blade bait, Jigging spoon |
Spring puts rock bass in skinny water — 2 to 10 ft is the zone. Warm water sends them out to 5 to 20 ft; cold water stacks them in 12 to 30 ft. Main-lake point is the standout, a point at roughly 28 ft, rated good for fall rock bass. Plan around the evening in the warm months. A ned rig (small) or a marabou jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | open water | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Main-lake point (28 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | open water | Tungsten jig + plastic, Small spoon + spike |
