124-acre reservoir near Oneida. The lake tops out around 9 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. What the data behind the map says about each species, season by season:
Shoreline on the chart totals 5.3 miles. An index of 2.7 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. End to end it runs roughly 2.1 mi, about 0.4 mi across. You'll find it in Oneida County. Closest neighbour on DepthScout: Newton Reservoir, 38 mi east of here.
Early season cutthroat trout use the shallows, holding in 2 to 9 ft. Even in summer they hold at 3 to 9 ft; winter keeps them in 2 to 9 ft. Put Break off the point first on the milk run — a drop-off near 4 ft that grades prime for summer. In summer the feeding windows fall in early morning and the evening. Tie on a trolled spoon (small) or an inline spinner 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 9 ft chart-limited; documented 3 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver/gold), Small spoon |
| Summer | 3 to 9 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Break off the point (4 ft) | Trolled spoon (small), Inline spinner |
| Fall | 2 to 9 ft chart-limited; documented 5 to 25 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Inline spinner |
| Winter | 2 to 9 ft chart-limited; documented 10 to 40 ft | dawn | Break off the point (4 ft) | Small jigging spoon, Marabou jig |
The spring pattern is a shallow one: rainbow trout in 2 to 9 ft. The depth story barely changes: 2 to 9 ft through summer, 2 to 9 ft in winter. Top water on the chart: Break off the point, a drop-off in the 4 ft range, prime in winter. Time it for early morning and the evening. Summer baits: a dodger + spoon (deep troll) or a flutter spoon gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft chart-limited; documented 5 to 20 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 2 to 9 ft chart-limited; documented 8 to 30 ft | dawn & dusk | Break off the point (4 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 3 to 9 ft chart-limited; documented 10 to 35 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 2 to 9 ft chart-limited; documented 8 to 40 ft | dawn | Break off the point (4 ft) | Jigging spoon, Tube jig (white) |
In spring, largemouth bass run shallow here, mostly 2 to 9 ft. Summer keeps them at 3 to 9 ft, and they winter in 3 to 9 ft. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 9 ft chart-limited; documented 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
| Summer | 3 to 9 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 2 to 9 ft chart-limited; documented 4 to 15 ft | midday & dawn | Main-lake point (8 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 3 to 9 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (4 ft) | Blade bait, Jigging spoon |
Spring puts crappie in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 9 ft; cold water stacks them in 3 to 9 ft. Deep basin is the standout, a deep basin at roughly 8 ft, rated prime for winter crappie. Plan around early morning and the evening in the warm months. A jig trolled/spider-rigged or a small crankbait (trolled) covers the summer program.

Anglers target cutthroat trout, rainbow trout, largemouth bass, crappie on Stone Reservoir.
Break off the point is the top-rated area: a drop-off in about 4 ft of water that rates prime for cutthroat trout in summer. Every other rated spot, per species and season, is on the map above.
For cutthroat trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
