1,138-acre lake in Thunder Bay District, Ontario. The lake tops out around 7 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. Species by species, here's what the data says the year looks like.
Seagram Lake maps at 1,143 acres behind 16.5 miles of shoreline, broken up by 25 islands. That shoreline is heavily fingered (development index 3.5) — bays, points and pockets everywhere, which multiplies the fishable edge. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Tip to tip the water measures near 3.4 mi with a 1.5-mi widest point. It sits in Thunder Bay District. McKay Lake sits 3 mi south — the closest neighbouring chart.
Start shallow in spring: walleye sit in 2 to 7 ft that time of year. They don't go far with the seasons — 2 to 7 ft covers summer, 2 to 7 ft covers winter. Top water on the chart: Break off the point, a drop-off in the 3 ft range, prime in fall. Fish it in the evening and early morning and you'll meet the bite. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft | dusk & dawn | Main-lake point (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 2 to 7 ft | dusk & dawn | Break off the point (3 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 2 to 7 ft | dusk & night | Break off the point (3 ft) | Jigging rap, Jig + big minnow |
| Winter | 2 to 7 ft | dusk & dawn | Deep basin (7 ft) | Jigging spoon + minnow head, Rattle bait |
Spring northern pike on Seagram Lake hold shallow, usually 2 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 2 to 7 ft once it turns cold. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
