87-acre lake near Ogemaw County. The lake tops out around 16 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.
On the chart, Flowage Lake draws 66 acres inside 2.1 miles of shoreline. Index 1.9 on the shoreline: a few honest points and pockets, nothing labyrinthine. End to end it runs roughly 0.7 mi, about 0.4 mi across. You'll find it in Ogemaw County. Closest neighbour on DepthScout: Peach Lake, 3 mi northeast of here.
Spring yellow perch on Flowage Lake hold shallow, usually 3 to 12 ft. They move out to 5 to 16 ft in summer and finish the year down in 5 to 16 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 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 12 ft | midday & dawn | Shallow bay flat (6 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 16 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 16 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts smallmouth bass in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 5 to 16 ft; cold water stacks them in 5 to 16 ft. Main-lake point is the standout, a point at roughly 5 ft, rated prime for fall smallmouth bass. Plan around early morning and the evening in the warm months. A drop shot (goby/minnow) or a ned rig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (5 ft) | Ned rig, Tube jig |
| Summer | 5 to 16 ft | dawn & dusk | Break off the point (9 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 5 to 16 ft | midday & dawn | Main-lake point (5 ft) | Jerkbait, Blade bait |
| Winter | 5 to 16 ft | midday | Break off the point (9 ft) | Blade bait, Hair jig |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 5 to 16 ft before dropping to 5 to 16 ft for winter. Spring largemouth bass concentrate at Shallow bay flat, a prime-rated weed flat around 6 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 10 ft | dawn & dusk | Shallow bay flat (6 ft) | Spinnerbait, Chatterbait |

| Fall | 4 to 15 ft | midday & dawn | Main-lake point (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 5 to 16 ft | midday | Break off the point (9 ft) | Blade bait, Jigging spoon |
When the water first warms, rock bass slide up into 2 to 10 ft. Summer is a 4 to 16 ft game here, winter a 5 to 16 ft one. Start at Main-lake point. It's a point holding about 5 ft of water and rates prime come summer. The feeding windows run the evening. Keep a ned rig (small) or a marabou jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (5 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 4 to 16 ft | dusk | Main-lake point (5 ft) | Ned rig (small), Marabou jig |

Deep basin is the standout, a deep basin at roughly 15 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.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | 1/16 oz jig + tube, Curly-tail grub |
