87-acre reservoir in Oneida County, Wisconsin. The lake tops out around 11 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. The season-by-season read for each species follows, from the map's own numbers.
On the chart, Rocky Run Flowage draws 87 acres inside 4.9 miles of shoreline — one island included. That shoreline is heavily fingered (development index 3.7) — bays, points and pockets everywhere, which multiplies the fishable edge. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. End to end it runs roughly 1.1 mi, about 0.4 mi across. You'll find it in Oneida County. The nearest mapped water is Hughitt Lake, 2 mi to the northwest.
The spring pattern is a shallow one: rainbow trout in 3 to 11 ft. The depth story barely changes: 3 to 11 ft through summer, 2 to 11 ft in winter. Top water on the chart: Break off the point, a drop-off in the 5 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 | 3 to 11 ft | dawn & dusk | Main-lake point (8 ft) | Inline spinner (silver), Small spoon |
| Summer | 3 to 11 ft | dawn & dusk | Break off the point (5 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 3 to 11 ft | dawn & dusk | Main-lake point (8 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 2 to 11 ft | dawn | Break off the point (5 ft) | Jigging spoon, Tube jig (white) |
Spring yellow perch on Rocky Run Flowage hold shallow, usually 3 to 11 ft. Depth-wise the year is flat: 3 to 11 ft in summer, 3 to 11 ft once it turns cold. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 11 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 3 to 11 ft; cold water stacks them in 3 to 11 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.

In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 3 to 11 ft before dropping to 3 to 11 ft for winter. 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.

|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (3 ft) | Spinnerbait, Chatterbait |
