138-acre lake in Leeds and Grenville United Counties, Ontario. The lake tops out around 35 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 1968, a decades-old survey (an MNRF lake survey). Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Little Crosby Lake draws 138 acres inside 2.7 miles of shoreline. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. Littoral water — the productive band under ~15 ft — makes up 96% of this chart. Tip to tip the water measures near 0.9 mi with a 0.4-mi widest point. You'll find it in Leeds and Grenville United Counties. For a second option, Crosby Lake lies 2 mi west.
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 15 to 35 ft, and by winter most fish are in 11 to 35 ft. If you only fish one area, make it Break off the point: a drop-off around 18 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (18 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 11 to 35 ft | dusk & night | Break off the point (18 ft) | Jigging rap, Jig + big minnow |
| Winter | 11 to 35 ft | dusk & dawn | Deep basin (34 ft) | Jigging spoon + minnow head, Rattle bait |
