335-acre lake near Presque Isle County. The lake tops out around 98 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. Here's the year, species by species, as the scoring engine sees it.
Rainy Lake's chart carries 3.7 miles of bank. A middling shoreline index (1.8) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 53% of this chart. The basin spans about 1.3 mi end to end and 0.7 mi across at its widest. Presque Isle County claims this one. Kelsey Lake sits 2 mi east — the closest neighbouring chart.
Come spring, look for rainbow trout tight to the bank in 5 to 20 ft. They move out to 8 to 30 ft in summer and finish the year down in 8 to 40 ft. If you only fish one area, make it Break off the point: a drop-off around 16 ft that scores prime in winter. Best bite is early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (6 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Break off the point (16 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Break off the point (16 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (16 ft) | Jigging spoon, Tube jig (white) |
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 15 to 35 ft, and winter fish settle into 20 to 40 ft. The spot to know is Break off the point, a drop-off in about 16 ft of water that rates prime for walleye in fall. Warm-month bites cluster around the evening and early morning. Throw a crawler harness on bottom bouncer or a deep crankbait (trolled) until the fish tell you otherwise.

|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (6 ft) | 1/8 oz jig + minnow, Hair jig |
