11-acre lake in Nipissing District, Ontario. The lake tops out around 30 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 the Ontario MNRF survey of 1970, a decades-old survey (an MNRF lake survey). Species by species, here's what the data says the year looks like.
Traced from the shoreline, Barnett L. runs 11 acres with 0.6 miles of edge. Its 1.3 shoreline index means few bank features; the contours below do the pattern work. The water lies in Nipissing District. For a second option, Coppersand Lake lies 1 mi southwest.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 3 to 20 ft for winter. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 11 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
