12-acre lake in Timiskaming District, Ontario. The lake tops out around 40 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 rest of this page walks each species through its year, using the map's own scoring.
On the chart, Burt L. 4 draws 12 acres inside 0.7 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. 59% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 0.3 mi. You'll find it in Timiskaming District. The nearest mapped water is Burt Lake, 1 mi to the north.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. As the season builds they drop to 10 to 30 ft, wintering in 3 to 20 ft. Winter brook trout concentrate at Shoreline break, a prime-rated drop-off around 6 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
