22-acre lake near Gladwin 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. The season-by-season read for each species follows, from the map's own numbers.
Round Lake maps at 25 acres behind 0.8 miles of shoreline. The basin is a simple one (shoreline index 1.2) — close to a bowl, so the structure on the chart matters more than the bank. The shallow band under 15 ft claims about 63% of the surface — that's where the groceries are. End to end it runs roughly 0.3 mi, about 0.2 mi across. Gladwin County claims this one. Lake Four sits 5 mi north — the closest neighbouring chart.
Spring brook trout on Round Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Deep basin first on the milk run — a deep basin near 29 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (5 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Deep basin (29 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (5 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (14 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring puts brown trout in skinny water — 3 to 25 ft is the zone. As the season builds they drop to 9 to 30 ft, wintering in 4 to 30 ft. Summer brown trout concentrate at Break off the point, a prime-rated drop-off around 14 ft. Warm-month bites cluster around after dark and early morning. A spoon at the thermocline or a deep stickbait (night) covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | Main-lake point (5 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 9 to 30 ft | night & dawn | Break off the point (14 ft) | Spoon at the thermocline, Deep stickbait (night) |
| Fall | 5 to 30 ft | dusk & dawn | Main-lake point (5 ft) | Jerkbait over gravel, Casting spoon |
| Winter | 4 to 30 ft | dawn | Break off the point (14 ft) | Jigging spoon, Small stickbait (slow) |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 10 to 30 ft, and winter fish settle into 9 to 30 ft. The spot to know is Shallow bay flat, a weed flat in about 8 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (8 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (29 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft | midday | Deep basin (29 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (29 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, largemouth bass slide up into 2 to 10 ft. By summer they slide out to 8 to 20 ft, and by winter most fish are in 9 to 30 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 8 ft that scores prime in spring. In summer the feeding windows fall in early morning and the evening. Keep a texas-rigged 10" worm or a deep-diving crankbait rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (8 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (8 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (5 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 9 to 30 ft | midday | Break off the point (14 ft) | Blade bait, Jigging spoon |
The spring pattern is a shallow one: rock bass in 2 to 10 ft. Midsummer fish sit out in 5 to 20 ft before dropping to 12 to 30 ft for winter. The spot to know is Main-lake point, a point in about 5 ft of water that rates prime for rock bass in summer. Plan around the evening in the warm months. Summer baits: a ned rig (small) or a marabou jig gets it done.
| 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 | 5 to 20 ft | dusk | Main-lake point (5 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Break off the point (14 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Deep basin (29 ft) | Tungsten jig + plastic, Small spoon + spike |
When the water first warms, bluegill slide up into 1 to 6 ft. Summer is a 4 to 15 ft game here, winter a 10 to 25 ft one. Start at Shallow bay flat. It's a weed flat holding about 8 ft of water and rates prime come summer. The feeding windows run early morning and the evening. Keep a small sponge spider (fly) or a micro tube jig rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 6 ft | midday & dusk | Shallow bay flat (8 ft) | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | Shallow bay flat (8 ft) | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | Shallow bay flat (8 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | Deep basin (29 ft) | Tungsten ice jig + plastic, Tiny spoon |
