600-acre lake near Wollaston Lake. The lake tops out around 16 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. The rest of this page walks each species through its year, using the map's own scoring.
The outline encloses 599 acres, worked by 15 miles of shoreline, with 9 islands in the mix. A development index of 4.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 3.7 mi long by 0.6 mi wide at the broadest reach. It sits in Division No. 18. If the bite dies, Henday Lake is 4 mi to the west.
Spring puts lake whitefish in skinny water — 5 to 16 ft is the zone. Summer fish stay in 5 to 16 ft, and winter fish hold in 5 to 16 ft. Summer lake whitefish concentrate at Deep basin, a prime-rated deep basin around 14 ft. Warm-month bites cluster around early morning. A blade bait vertical or a small jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 16 ft | midday & dawn | open water | Small jig + waxworm, Blade bait (small) |
| Summer | 5 to 16 ft | dawn | Deep basin (14 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 4 to 16 ft | dusk | Main-lake point (8 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 5 to 16 ft | midday & dawn | Deep basin (14 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Spring northern pike on Mcmahon Lake hold shallow, usually 2 to 8 ft. They move out to 5 to 16 ft in summer and finish the year down in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| 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 | 5 to 16 ft | dawn & dusk | Main-lake point (8 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 5 to 16 ft | midday & dawn | Main-lake point (8 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 |
