465-acre lake in Rainy River District, Ontario. The lake tops out around 60 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Below is the species-by-species picture, pulled from the same data the map uses.
Drawn out, this is 467 acres of water rimmed by 8.7 miles of bank, with 5 islands in the mix. A development index of 2.9 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 49% of the water is 15 ft or less, the band where the food chain lives. Figure 1.8 mi of water from one end to the other, 0.8 mi at the beam. You'll find it in Rainy River District. The nearest mapped water is Bullmoose Lake, 1 mi to the northwest.
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 20 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 15 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
