56-acre lake in Renfrew County, Ontario. The lake tops out around 30 ft. The depth data here comes from the Ontario MNRF survey of 1970, a decades-old survey (a transect sounding survey). Here's the year, species by species, as the scoring engine sees it.
On the chart, Harvey Lake draws 57 acres inside 2.9 miles of shoreline, with a single island in the mix. An index of 2.7 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 80% of the surface — that's where the groceries are. The basin spans about 0.6 mi end to end and 0.5 mi across at its widest. You'll find it in Renfrew County. Closest neighbour on DepthScout: Way Lake, 1 mi north of here.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 3 to 20 ft. The spot to know is Deep basin, a deep basin in about 28 ft of water that rates prime for brook trout in summer. Warm-month bites cluster around early morning and the evening. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
