109-acre lake in Kenora District, Ontario. The lake tops out around 28 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 the Ontario MNRF survey of 1979, a decades-old survey (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
On the chart, Pritchard Lake draws 108 acres inside 1.7 miles of shoreline. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 0.5 mi of water from one end to the other, 0.5 mi at the beam. You'll find it in Kenora District. The nearest mapped water is Flambeau Lake, 1 mi to the southwest.
Spring cisco (lake herring) on Pritchard Lake hold shallow, usually 7 to 28 ft. Depth-wise the year is flat: 8 to 28 ft in summer, 8 to 28 ft once it turns cold. Put Deep basin first on the milk run — a deep basin near 23 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a vertical flutter spoon (small) or a drop-shot micro plastic.
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 | 7 to 28 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (23 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 8 to 28 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (23 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (13 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 8 to 28 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (23 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 8 to 28 ft, and by winter most fish are in 8 to 28 ft. If you only fish one area, make it Break off the point: a drop-off around 13 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Break off the point (13 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 28 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (13 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 28 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (13 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 28 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (23 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is an 8 to 28 ft game here, winter an 8 to 28 ft one. Start at Deep basin. It's a deep basin holding about 23 ft of water and rates prime come fall. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 28 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (23 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 28 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (23 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 28 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (23 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: northern pike in 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. The spot to know is Break off the point, a drop-off in about 13 ft of water that rates prime for northern pike in fall. Plan around early morning and the evening in the warm months. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.
| 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 (13 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (13 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Break off the point (13 ft) | Tip-ups, Large jigging spoon |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 23 ft.
