45-acre lake in Rainy River District, Ontario. The lake tops out around 20 ft. The depth data here comes from the Ontario MNRF survey of 1975, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
The drawn water covers 46 acres wrapped in 1.5 miles of bank. With a 1.6 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 44% of this chart. End to end it runs roughly 0.5 mi, about 0.3 mi across. It sits in Rainy River District. If the bite dies, This Man Lake is 3 mi to the northeast.
In spring, walleye run shallow here, mostly 4 to 15 ft. Midsummer fish sit out in 6 to 20 ft before dropping to 6 to 20 ft for winter. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 18 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (7 ft) | 1/8 oz jig + minnow, Hair jig |

It's a weed flat holding about 6 ft of water and rates prime come spring. The feeding windows run early morning and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.
