33-acre lake near Sunday Lake. The lake tops out around 20 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
Drawn out, this is 33 acres of water rimmed by 1 miles of bank. Nearly circular (index 1.2), so the story is the bottom, not the bank. About 90% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.4 mi, about 0.2 mi across. The water lies in Snohomish County. The nearest mapped water is Bryant Lake, 5 mi to the east.
Come spring, look for cutthroat trout tight to the bank in 3 to 15 ft. They move out to 6 to 20 ft in summer and finish the year down in 5 to 20 ft. If you only fish one area, make it Break off the point: a drop-off around 19 ft that scores prime in summer. Best bite is early morning and the evening. A trolled spoon (small) or an inline spinner is the honest summer answer here.
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 | 3 to 15 ft | dawn & dusk | Main-lake point (9 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 6 to 20 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Break off the point (19 ft) | Trolled spoon (small), Inline spinner |
| Fall | 4 to 20 ft chart-limited; documented 5 to 25 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon, Inline spinner |
| Winter | 5 to 20 ft chart-limited; documented 10 to 40 ft | dawn | Break off the point (19 ft) | Small jigging spoon, Marabou jig |
In spring, brown bullhead run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 3 to 12 ft, and winter fish settle into 6 to 20 ft. Deep basin is the standout, a deep basin at roughly 19 ft, rated prime for winter brown bullhead. Time it for after dark and the evening.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 12 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 5 to 15 ft | dusk | Shallow bay flat (3 ft) | |
| Winter | 6 to 20 ft chart-limited; documented 10 to 25 ft | midday | Deep basin (19 ft) |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. As the season builds they drop to 8 to 20 ft, wintering in 6 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a texas-rigged 10" worm or a deep-diving crankbait gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (19 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (9 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 20 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (19 ft) | Blade bait, Jigging spoon |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 6 to 18 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (3 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Deep basin (19 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 6 to 20 ft, then a winter hold in 6 to 20 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
