15-acre lake in Sudbury District, Ontario. The lake tops out around 65 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from a transect sounding survey by the Ontario MNRF. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Harrow L. 28 draws 14 acres inside 1 miles of shoreline. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 32% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.4 mi of water from one end to the other. You'll find it in Sudbury District. For a second option, White's Lake lies 2 mi east.
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 Main-lake point, a point in about 13 ft of water that rates prime for brook trout in spring. 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.
