12-acre lake in Algoma District, Ontario. The lake tops out around 22 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 1979, a decades-old survey (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
On the chart, Gunterman L. 19 draws 13 acres inside 0.7 miles of shoreline. Its 1.4 shoreline index means few bank features; the contours below do the pattern work. Littoral water — the productive band under ~15 ft — makes up 74% of this chart. Figure 0.3 mi of water from one end to the other. The water lies in Algoma District. The nearest mapped water is Strouth Lake, 0 mi to the south.
The spring pattern is a shallow one: brook trout in 2 to 15 ft. Midsummer fish sit out in 7 to 22 ft before dropping to 3 to 20 ft for winter. The spot to know is Deep basin, a deep basin in about 20 ft of water that rates prime for brook trout in summer. Plan around early morning and the evening in the warm months. Summer baits: a small spoon fished deep or a trolled lake-clear wobbler + worm gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (12 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 7 to 22 ft | dawn & dusk | Deep basin (20 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (12 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Deep basin (20 ft) | Small jigging spoon, Tungsten jig + plastic |
Structure-wise the chart holds 4 features, led in depth by Deep basin at roughly 20 ft.
