151-acre lake near Mason County. The lake tops out around 25 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 151 acres wrapped in 2 miles of bank. A shoreline index of 1.1 says round and simple: fish relate to depth changes here, not shoreline features. About 61% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 0.8 mi end to end and 0.5 mi across at its widest. It sits in Mason County. Its nearest charted neighbour, Spencer Lake, is 1 mi to the north.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 8 to 25 ft, then a winter hold in 3 to 20 ft. Put Creek inflow first on the milk run — an inflow / creek mouth near 25 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
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 | 2 to 15 ft | dawn & dusk | Main-lake point (1 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 8 to 25 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Creek inflow (25 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (1 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (9 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring rainbow trout on Phillips Lake hold shallow, usually 5 to 20 ft. By summer they slide out to 7 to 25 ft, and by winter most fish are in 5 to 25 ft. The chart's best answer is Creek inflow — inflow / creek mouth, 25 ft, prime for summer. 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 | Break off the point (9 ft) | Inline spinner (silver), Small spoon |
| Summer | 7 to 25 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Creek inflow (25 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 7 to 25 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Old creek channel (25 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 5 to 25 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (9 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for bluegill tight to the bank in 1 to 6 ft. Expect a summer slide to 4 to 15 ft, then a winter hold in 10 to 25 ft. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A small sponge spider (fly) or a micro tube jig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (1 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (1 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Break off the point (9 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (25 ft) | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for largemouth bass tight to the bank in 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 8 to 25 ft. If you only fish one area, make it Break off the point: a drop-off around 9 ft that scores prime in winter. Best bite is early morning and the evening. A texas-rigged 10" worm or a deep-diving crankbait is the honest summer answer here.
