17-acre lake in Cochrane District, Ontario. The lake tops out around 70 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.
Traced from the shoreline, Pearce L. 30 runs 17 acres with 0.7 miles of edge. Nearly circular (index 1.3), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 47% of this chart. End to end it runs roughly 0.3 mi. You'll find it in Cochrane District. For a second option, Pearce Lake 27 lies 1 mi south.
