13-acre lake in Muskoka District Municipality, Ontario. The lake tops out around 25 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 12 acres, worked by 0.6 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. 53% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Muskoka District Municipality claims this one. Its nearest charted neighbour, Loon Lake, is 1 mi to the north.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 8 to 25 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 21 ft that scores prime in summer. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 25 ft | dawn & dusk | Deep basin (21 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shoreline break (11 ft) | Small jigging spoon, Tungsten jig + plastic |
4 pieces of structure are mapped here — Deep basin, around 21 ft, is the deepest of them.
