68-acre lake in Nipissing District, Ontario. The lake tops out around 295 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 69 acres, worked by 2.8 miles of shoreline. With a shoreline index of 2.4, this water is all arms and coves — edge habitat well beyond its acreage. 15% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Figure 1.1 mi of water from one end to the other, 0.3 mi at the beam. Nipissing District claims this one. Its nearest charted neighbour, Lake Travers, is 5 mi to the northeast.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Shallow bay flat: a feeding flat around 6 ft that scores good in spring. 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 (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | 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 | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
