21-acre lake in Parry Sound District, Ontario. The lake tops out around 63 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 1971, a decades-old survey (an MNRF lake survey). Below is the species-by-species picture, pulled from the same data the map uses.
The outline encloses 21 acres, worked by 0.8 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 65% of this chart. Tip to tip the water measures near 0.3 mi. Parry Sound District claims this one. If the bite dies, Lambs Lake is 1 mi to the north.
Spring brook trout on East Tower L. hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Shoreline break first on the milk run — a drop-off near 6 ft that grades prime for winter. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shoreline break (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Shoreline break (6 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 (6 ft) | Small jigging spoon, Tungsten jig + plastic |
