335-acre lake near Mason County. The lake tops out around 30 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Drawn out, this is 335 acres of water rimmed by 3 miles of bank. A shoreline index of 1.2 says round and simple: fish relate to depth changes here, not shoreline features. 59% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. End to end it runs roughly 1.1 mi, about 0.7 mi across. You'll find it in Mason County. Closest neighbour on DepthScout: Phillips Lake, 1 mi south of here.
Come spring, look for cutthroat trout tight to the bank in 3 to 15 ft. Expect a summer slide to 9 to 30 ft, then a winter hold in 8 to 30 ft. Start at Creek inflow. It's an inflow / creek mouth holding about 7 ft of water and rates prime come spring. Prime time lands in 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 | Creek inflow (7 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 9 to 30 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Creek inflow (7 ft) | Trolled spoon (small), Inline spinner |
| Fall | 5 to 25 ft | dawn & dusk | Creek inflow (7 ft) | Casting spoon, Inline spinner |
| Winter | 8 to 30 ft chart-limited; documented 10 to 40 ft | dawn | Deep basin (30 ft) | Small jigging spoon, Marabou jig |
Spring puts rainbow trout in skinny water — 5 to 20 ft is the zone. As the season builds they drop to 8 to 30 ft, wintering in 6 to 30 ft. Spring rainbow trout concentrate at Creek inflow, a prime-rated inflow / creek mouth around 7 ft. Warm-month bites cluster around early morning and the evening. A dodger + spoon (deep troll) or a flutter spoon covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Creek inflow (7 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Creek inflow (7 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 9 to 30 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Old creek channel (7 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 6 to 30 ft chart-limited; documented 8 to 40 ft | dawn | Deep basin (30 ft) | Jigging spoon, Tube jig (white) |
The spring pattern is a shallow one: largemouth bass in 2 to 10 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 9 to 30 ft for winter. The spot to know is Old creek channel, a creek channel in about 7 ft of water that rates prime for largemouth bass in fall. Plan around early morning and the evening in the warm months. 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 (1 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | open water | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Old creek channel (7 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 9 to 30 ft chart-limited; documented 15 to 35 ft | midday | Deep basin (30 ft) | Blade bait, Jigging spoon |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. Warm water sends them out to 10 to 30 ft; cold water stacks them in 9 to 30 ft. Top water on the chart: Creek inflow, an inflow / creek mouth in the 7 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.

| Winter | 9 to 30 ft chart-limited; documented 20 to 45 ft | midday | Deep basin (30 ft) | Blade bait, Hair jig |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 9 to 30 ft. If you only fish one area, make it Deep basin: a deep basin around 30 ft that scores prime in fall. Best bite is early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
