69-acre lake in Algoma District, Ontario. The lake tops out around 89 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Marten Lake runs 70 acres with 2.3 miles of edge. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 26% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.7 mi end to end and 0.4 mi across at its widest. You'll find it in Algoma District. The nearest mapped water is Chickenhawk L., 1 mi to the west.
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 6 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: burbot sit in 25 to 70 ft that time of year. Warm water sends them out to 27 to 89 ft; cold water stacks them in 15 to 60 ft. Top water on the chart: Deep basin, a deep basin in the 76 ft range, prime in summer. Fish it in after dark and midday and you'll meet the bite. Throw a heavy jig + cut bait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Deep basin (76 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 27 to 89 ft | night & midday | Deep basin (76 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (76 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (40 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
