8-acre lake in Sudbury District, Ontario. The lake tops out around 16 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. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Chappise L. 8 runs 8 acres with 0.5 miles of edge. The basin is a simple one (shoreline index 1.3) — close to a bowl, so the structure on the chart matters more than the bank. The water lies in Sudbury District. The nearest mapped water is Seven Mile Lake, 1 mi to the south.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 5 to 16 ft; cold water stacks them in 2 to 16 ft. Top water on the chart: Deep basin, a deep basin in the 12 ft range, prime in summer. Fish it in early morning and the evening and you'll meet the bite. Throw a small spoon fished deep or a trolled lake-clear wobbler + worm until the fish tell you otherwise.
