538-acre lake in Rainy River District, Ontario. The lake tops out around 210 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 538 acres, worked by 11.6 miles of shoreline. With a shoreline index of 3.6, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 58% of the surface on the model — that's where the groceries are. Figure 2.2 mi of water from one end to the other, 1.1 mi at the beam. It sits in Rainy River District. Its nearest charted neighbour, Three Island Lake, is 1 mi to the west.
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Put Break off the point first on the milk run — a drop-off near 95 ft that grades prime for summer. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
