101-acre lake in Rainy River District, Ontario. The lake tops out around 43 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Boot Lake runs 100 acres with 3.4 miles of edge. The 2.4 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. About 65% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 1 mi of water from one end to the other, 0.5 mi at the beam. You'll find it in Rainy River District. The nearest mapped water is Crystal Lake, 2 mi to the north.
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 13 to 43 ft. Main-lake point is the standout, a point at roughly 11 ft, rated prime for fall smallmouth bass. Plan around early morning and the evening in the warm months. A drop shot (goby/minnow) or a ned rig covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (11 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (19 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (11 ft) | Jerkbait, Blade bait |
| Winter | 13 to 43 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (19 ft) | Blade bait, Hair jig |
