Rating depth structure for rainbow trout.

50-acre lake near Blaine. The lake tops out around 20 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. What the data behind the map says about each species, season by season:
Perkins Lake maps at 53 acres behind 1.5 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. About 69% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Call it 0.5 mi long by 0.3 mi wide at the broadest reach. It sits in Blaine County. Its nearest charted neighbour, Pettit Lake, is 4 mi to the northwest.
Spring rainbow trout on Perkins Lake hold shallow, usually 5 to 20 ft. Depth-wise the year is flat: 5 to 20 ft in summer, 4 to 20 ft once it turns cold. The chart's best answer is Break off the point — drop-off, 9 ft, prime for winter. Prime time lands in early morning and the evening. The summer box starts with a dodger + spoon (deep troll) or a flutter spoon.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 5 to 20 ft | dawn & dusk | Break off the point (9 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 6 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 4 to 20 ft | dawn | Break off the point (9 ft) | Jigging spoon, Tube jig (white) |
Early season arctic grayling use the shallows, holding in 2 to 10 ft. Expect a summer slide to 3 to 15 ft, then a winter hold in 6 to 20 ft. Put Deep basin first on the milk run — a deep basin near 17 ft that grades prime for winter. In summer the feeding windows fall in the evening and early morning. Tie on a dry fly (parachute adams, elk hair caddis) or a small inline spinner and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dusk | Shallow bay flat (3 ft) | 1/16 oz spinner (silver), Small dry fly (Adams, Griffith's) |
| Summer | 3 to 15 ft | dusk & dawn | Break off the point (9 ft) | Dry fly (parachute Adams, elk hair caddis), Small inline spinner |
| Fall | 6 to 20 ft | midday | Break off the point (9 ft) | Small spoon, Beadhead nymph under indicator |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (17 ft) | Tungsten jig + waxworm, Small jigging spoon (gold) |
