2,517-acre lake in Kenora District, Ontario. The lake tops out around 25 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 a transect sounding survey by the Ontario MNRF. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Rugby Lake runs 2,528 acres with 24.2 miles of edge, broken up by 6 islands. A development index of 3.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Roughly 84% of the water is 15 ft or less, the band where the food chain lives. Figure 5.6 mi of water from one end to the other, 2.7 mi at the beam. The water lies in Kenora District. For a second option, Wickens Lake lies 2 mi east.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

When the water first warms, cisco (lake herring) slide up into 6 to 25 ft. There's no big seasonal slide here — summer means 8 to 25 ft, winter 8 to 25 ft. If you only fish one area, make it Deep basin: a deep basin around 25 ft that scores prime in spring. In summer the feeding windows fall in early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
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 | 6 to 25 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (25 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 8 to 25 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (25 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Gravel shoal (3 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 8 to 25 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (25 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Early season walleye use the shallows, holding in 4 to 15 ft. Summer is an 8 to 25 ft game here, winter an 8 to 25 ft one. The chart's best answer is Break off the point — drop-off, 10 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Gravel shoal (3 ft) | 1/8 oz jig + minnow, Hair jig |

When the water first warms, sauger slide up into 4 to 18 ft. Summer is an 8 to 25 ft game here, winter an 8 to 25 ft one. Start at Deep basin. It's a deep basin holding about 25 ft of water and rates prime come winter. The feeding windows run early morning and the evening. Keep a bottom bouncer + crawler or a 3-way rig with stickbait rigged through the warm months.

Spring yellow perch on Rugby Lake hold shallow, usually 3 to 12 ft. By summer they slide out to 8 to 25 ft, and by winter most fish are in 8 to 25 ft. The chart's best answer is Deep basin — deep basin, 25 ft, prime for fall. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Fall northern pike concentrate at Break off the point, a prime-rated drop-off around 10 ft. Warm-month bites cluster around early morning and the evening. 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 (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (10 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (10 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Feeding flat (10 ft) | Tip-ups, Large jigging spoon |
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. As the season builds they drop to 8 to 25 ft, wintering in 8 to 25 ft. Winter smallmouth bass concentrate at Break off the point, a prime-rated drop-off around 10 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.
