23-acre lake near T4 R5 NBKP. The lake tops out around 11 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
The outline encloses 23 acres, worked by 1 miles of shoreline — one island included. A middling shoreline index (1.5) gives it some bays to work without being a maze. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. End to end it runs roughly 0.3 mi, about 0.2 mi across. It sits in Somerset County. If the bite dies, Big Grenier Pond is 1 mi to the northeast.
Come spring, look for brook trout tight to the bank in 1 to 11 ft. Through summer count on 3 to 11 ft; the winter hold is 2 to 11 ft. Start at Deep basin. It's a deep basin holding about 9 ft of water and rates prime come summer. Prime time lands in 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 | 1 to 11 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 3 to 11 ft | dawn & dusk | Deep basin (9 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 1 to 11 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 11 ft | dawn | Deep basin (9 ft) | Small jigging spoon, Tungsten jig + plastic |
