90-acre lake in Peterborough County, Ontario. The lake tops out around 60 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
On the chart, Loucks Lake draws 91 acres inside 3 miles of shoreline, with a single island in the mix. With a shoreline index of 2.3, this water is all arms and coves — edge habitat well beyond its acreage. The shallow band under 15 ft claims about 34% of the surface — that's where the groceries are. Call it 1 mi long by 0.3 mi wide at the broadest reach. You'll find it in Peterborough County. Closest neighbour on DepthScout: Buzzard Lake, 1 mi southeast of here.
Start shallow in spring: lake trout sit in 10 to 40 ft that time of year. Warm water sends them out to 18 to 60 ft; cold water stacks them in 15 to 60 ft. Top water on the chart: Deep basin, a deep basin in the 60 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a white tube jig (deep) or a magnum spoon on downrigger until the fish tell you otherwise.
