24-acre lake in Sudbury District, Ontario. The lake tops out around 20 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. Here is how the season plays out for each species, straight from the data behind the map.
Drawn out, this is 24 acres of water rimmed by 0.9 miles of bank. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. The basin spans about 0.4 mi end to end and 0.2 mi across at its widest. The water lies in Sudbury District. The nearest mapped water is Cunningham L. 793844, 8 mi to the northeast.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 6 to 20 ft; cold water stacks them in 3 to 20 ft. Deep basin is the standout, a deep basin at roughly 15 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. 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 |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Small inline spinner (gold), Tiny spoon |

| Winter | 3 to 20 ft | dawn | Deep basin (15 ft) | Small jigging spoon, Tungsten jig + plastic |
