26-acre lake in Algoma District, Ontario. The lake tops out around 69 ft. The depth data here comes from the Ontario MNRF survey of 1975, a decades-old survey (a transect sounding survey). What the data behind the map says about each species, season by season:
Winchester Lake maps at 26 acres behind 1.4 miles of shoreline. With a 2 development index there's bank structure worth casting at, in moderation. 26% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 0.5 mi of water from one end to the other, 0.2 mi at the beam. It sits in Algoma District. If the bite dies, Stewleen Lake is 1 mi to the northeast.
Spring brook trout on Winchester Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Secondary point — point, 8 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
