521-acre lake near Lambert Lake Township. The lake tops out around 60 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
The outline encloses 520 acres, worked by 6.6 miles of shoreline, broken up by an island. A middling shoreline index (2.1) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 33% of this chart. Tip to tip the water measures near 2.9 mi with a 0.5-mi widest point. It sits in Washington County. Spednic Lake sits 6 mi north — the closest neighbouring chart.
When the water first warms, brook trout slide up into 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. If you only fish one area, make it Main-lake point: a point around 8 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a small spoon fished deep or a trolled lake-clear wobbler + worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (32 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Back-bay flat (5 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for landlocked salmon tight to the bank in 1 to 15 ft. Expect a summer slide to 25 to 60 ft, then a winter hold in 10 to 40 ft. Start at Deep basin. It's a deep basin holding about 55 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A dodger + streamer down deep or a thin spoon on lead core is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Streamer flies (Grey Ghost) off boards, Thin spoon (Mooselook style) |
| Summer | 25 to 60 ft | dawn & dusk | Deep basin (55 ft) | Dodger + streamer down deep, Thin spoon on lead core |
| Fall | 5 to 30 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon at the mouths, Streamers |
| Winter | 10 to 40 ft | dawn | Break off the point (32 ft) | Small jigging spoon, Swedish pimple + smelt |
Spring brown bullhead on Lambert Lake hold shallow, usually 2 to 8 ft. By summer they slide out to 3 to 12 ft, and by winter most fish are in 10 to 25 ft. The chart's best answer is Shallow bay flat — weed flat, 2 ft, prime for spring. Prime time lands in after dark and the evening.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (2 ft) | |
| Summer | 3 to 12 ft | night & dusk | Back-bay flat (5 ft) | |
| Fall | 5 to 15 ft | dusk | Back-bay flat (5 ft) | |
| Winter | 10 to 25 ft | midday | Deep basin (55 ft) |
Spring puts pumpkinseed in skinny water — 1 to 8 ft is the zone. As the season builds they drop to 2 to 10 ft, wintering in 6 to 18 ft. Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Warm-month bites cluster around the evening and early morning. A micro tube or a sponge spider (fly) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (2 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (2 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Back-bay flat (5 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Back-bay flat (5 ft) | Tungsten ice jig + plastic, Tiny spoon |
Spring smallmouth bass on Lambert Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 20 to 45 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for fall. The feeding windows run early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.
| 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 | 10 to 30 ft | dawn & dusk | Break off the point (32 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (32 ft) | Blade bait, Hair jig |
When the water first warms, white perch slide up into 4 to 15 ft. By summer they slide out to 15 to 40 ft, and by winter most fish are in 20 to 50 ft. If you only fish one area, make it Break off the point: a drop-off around 32 ft that scores prime in fall. In summer the feeding windows fall in early morning. Keep a small spinner rig drifted or a 1/8 oz jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Back-bay flat (5 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 15 to 40 ft | dawn | Break off the point (32 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 15 to 45 ft | midday | Break off the point (32 ft) | Jigging spoon (small), Blade bait |
| Winter | 20 to 50 ft | dusk | Deep basin (55 ft) | Small rattle spoon, Tungsten + spikes |
