30-acre lake in Timiskaming District, Ontario. The lake tops out around 25 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. Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Geraldine Lake draws 30 acres inside 1 miles of shoreline. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. Figure 0.4 mi of water from one end to the other, 0.2 mi at the beam. The water lies in Timiskaming District. Closest neighbour on DepthScout: Dixon Lake, 0 mi east of here.
Start shallow in spring: brook trout sit in 2 to 15 ft that time of year. Warm water sends them out to 8 to 25 ft; cold water stacks them in 3 to 20 ft. Top water on the chart: Deep basin, a deep basin in the 14 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.
