166-acre lake in Algoma District, Ontario. The lake tops out around 140 ft. The depth data here comes from the Ontario MNRF survey of 1972, a decades-old survey (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
Traced from the shoreline, Bobowash Lake runs 167 acres with 6.8 miles of edge, broken up by 8 islands. A development index of 3.7 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 19% of the water is 15 ft or less, the band where the food chain lives. End to end it runs roughly 1 mi, about 0.7 mi across. You'll find it in Algoma District. The nearest mapped water is Dollyberry Lake, 1 mi to the south.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 50 to 120 ft; cold water stacks them in 20 to 80 ft. Top water on the chart: Main-lake point, a point in the 10 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (136 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (46 ft) | White tube jig, Airplane jig |
Bobowash Lake carries 7 mapped structure features, topping out (or rather bottoming out) at Deep basin, about 136 ft down.
