460-acre section. Shallow, weedy Sturgeon Bay off Waubaushene: a muskie and pike bay with largemouth in the cabbage and panfish everywhere. The lake tops out around 12 ft. The depth chart is built from real NOAA hydrographic survey soundings, so the humps, channels and drop-offs you see are measured, not guessed. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 463 acres, worked by 3.5 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. Call it 1.4 mi long by 0.6 mi wide at the broadest reach. Georgian Bay - Midland Bay sits 2 mi west — the closest neighbouring chart.
Early season largemouth bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 4 to 12 ft, then a winter hold in 4 to 12 ft. Put Weed flat first on the milk run — a weed flat near 8 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 | Weed flat (8 ft) | Spinnerbait, Chatterbait |
| Summer | 4 to 12 ft | dawn & dusk | Sharp break (5 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 3 to 12 ft | midday & dawn | Shoreline point (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 4 to 12 ft | midday | Sharp break (5 ft) | Blade bait, Jigging spoon |
Spring smallmouth bass on Georgian Bay - Sturgeon Bay hold shallow, usually 3 to 12 ft. Depth-wise the year is flat: 4 to 12 ft in summer, 4 to 12 ft once it turns cold. The chart's best answer is Shoreline point — point, 5 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a drop shot (goby/minnow) or a ned rig.

|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Shoreline point (5 ft) | Ned rig, Tube jig |

Spring northern pike on Georgian Bay - Sturgeon Bay hold shallow, usually 2 to 8 ft. By summer they slide out to 4 to 12 ft, and by winter most fish are in 4 to 12 ft.

Spring muskellunge on Georgian Bay - Sturgeon Bay hold shallow, usually 3 to 12 ft. Depth-wise the year is flat: 4 to 12 ft in summer, 4 to 12 ft once it turns cold. Put Sharp break first on the milk run — a drop-off near 5 ft that grades prime for fall. The feeding windows run the evening and early morning. The summer box starts with a double-10 bucktail or a topwater (walk-the-dog / creeper).

Start shallow in spring: walleye sit in 3 to 12 ft that time of year. They don't go far with the seasons — 4 to 12 ft covers summer, 4 to 12 ft covers winter. The spot to know is Sharp break, a drop-off in about 5 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dusk & dawn | Shoreline point (5 ft) | 1/8 oz jig + minnow, Hair jig |

Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Summer fish stay in 4 to 12 ft, and winter fish hold in 4 to 12 ft. Spring yellow perch concentrate at Weed flat, a prime-rated weed flat around 8 ft. Warm-month bites cluster around early morning. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.
