109-acre lake in Kenora District, Ontario. The lake tops out around 46 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Grove Lake runs 110 acres with 2.3 miles of edge, broken up by an island. Index 1.6 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 33% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.8 mi end to end and 0.3 mi across at its widest. The water lies in Kenora District. For a second option, Unnamed Lake lies 0 mi north.
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.
