149-acre lake in Bruce County, Ontario. The lake tops out around 5 ft. The depth data here comes from the Ontario MNRF survey of 1971, a decades-old survey (a transect sounding survey). The rest of this page walks each species through its year, using the map's own scoring.
Upper Andrew Lake maps at 150 acres behind 6.9 miles of shoreline — 12 islands included. With a shoreline index of 4, this water is all arms and coves — edge habitat well beyond its acreage. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 1 mi with a 0.6-mi widest point. Bruce County claims this one. If the bite dies, Moore Lake is 1 mi to the northeast.
In spring, yellow perch run shallow here, mostly 1 to 5 ft. Summer keeps them at 2 to 5 ft, and they winter in 2 to 5 ft. Shallow bay flat is the standout, a weed flat at roughly 1 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 5 ft | dawn | Deep basin (5 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 2 to 5 ft | midday | Deep basin (5 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 5 ft | midday & dawn | Deep basin (5 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 1 to 5 ft. Even in summer they hold at 2 to 5 ft; winter keeps them in 2 to 5 ft. Put Shallow bay flat first on the milk run — a weed flat near 1 ft that grades prime for spring. In summer the feeding windows fall in early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 5 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |

In spring, rock bass run shallow here, mostly 1 to 5 ft. Summer keeps them at 1 to 5 ft, and they winter in 2 to 5 ft. Summer rock bass concentrate at Main-lake point, a prime-rated point around 1 ft. Fish it in the evening and you'll meet the bite. You won't need more than a ned rig (small) or a marabou jig most summer days.
| Season | Depth | Best window | Start at | Go-to baits |

In spring, pumpkinseed run shallow here, mostly 1 to 5 ft. Summer keeps them at 1 to 5 ft, and they winter in 2 to 5 ft. Spring pumpkinseed concentrate at Shallow bay flat, a prime-rated weed flat around 1 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a micro tube or a sponge spider (fly) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
