462-acre lake in Sudbury District, Ontario. The lake tops out around 54 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. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Ridout Lake runs 471 acres with 12.2 miles of edge — one island included. A development index of 4 means a maze of bays and points: far more casting targets than a round bowl of the same size. 68% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Call it 4.1 mi long by 0.7 mi wide at the broadest reach. You'll find it in Sudbury District. For a second option, Little Ridout Lake lies 1 mi southeast.
When the water first warms, lake whitefish slide up into 15 to 45 ft. Summer is a 16 to 54 ft game here, winter a 16 to 54 ft one. Start at Deep basin. It's a deep basin holding about 46 ft of water and rates prime come summer. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | Break off the point (24 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 16 to 54 ft | dawn | Deep basin (46 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Break off the point (24 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 16 to 54 ft | midday & dawn | Deep basin (46 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Put Break off the point first on the milk run — a drop-off near 24 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (14 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (24 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (24 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Break off the point (24 ft) | Jigging spoon + minnow head, Rattle bait |
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 |
