73-acre lake near Benzie County. The lake tops out around 20 ft. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
The drawn outline gives you 1.4 miles of bank to pick apart. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. About 89% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Call it 0.6 mi long by 0.2 mi wide at the broadest reach. You'll find it in Benzie County. The nearest mapped water is Bass Lake, 5 mi to the east.
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 6 to 20 ft, and by winter most fish are in 6 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 20 ft that scores prime in winter. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (6 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 20 ft | dusk & dawn | Main-lake point (6 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 20 ft | dusk & night | Main-lake point (6 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 20 ft | dusk & dawn | Deep basin (20 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, yellow perch slide up into 3 to 12 ft. Summer is a 6 to 20 ft game here, winter a 6 to 20 ft one. Start at Back-bay flat. It's a weed flat holding about 5 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Back-bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 6 to 20 ft | midday & dawn | Deep basin (20 ft) | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. Midsummer fish sit out in 6 to 20 ft before dropping to 6 to 20 ft for winter. The spot to know is Main-lake point, a point in about 6 ft of water that rates prime for smallmouth bass in fall. Plan around early morning and the evening in the warm months. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (6 ft) | Ned rig, Tube jig |
| Summer | 6 to 20 ft | dawn & dusk | Main-lake point (6 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 6 to 20 ft | midday & dawn | Main-lake point (6 ft) | Jerkbait, Blade bait |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) | Blade bait, Hair jig |
Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Warm water sends them out to 8 to 20 ft; cold water stacks them in 6 to 20 ft. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Fish it in early morning and the evening and you'll meet the bite. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Shallow bay flat (2 ft) | Spinnerbait, Chatterbait |
| Summer | 8 to 20 ft | dawn & dusk | Back-bay flat (5 ft) | Texas-rigged 10" worm, Deep-diving crankbait |
| Fall | 4 to 15 ft | midday & dawn | Main-lake point (6 ft) | Squarebill crankbait (shad), Spinnerbait |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) | Blade bait, Jigging spoon |
Spring rock bass on Turtle Lake hold shallow, usually 2 to 10 ft. They move out to 5 to 20 ft in summer and finish the year down in 6 to 20 ft. Put Main-lake point first on the milk run — a point near 6 ft that grades prime for summer. The feeding windows run the evening. The summer box starts with a ned rig (small) or a marabou jig.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (6 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (6 ft) | Ned rig (small), Marabou jig |
| Fall | 6 to 20 ft | midday | Main-lake point (6 ft) | Small tube jig, Inline spinner |
| Winter | 6 to 20 ft | midday | Deep basin (20 ft) | Tungsten jig + plastic, Small spoon + spike |
Spring puts white perch in skinny water — 4 to 15 ft is the zone. As the season builds they drop to 6 to 20 ft, wintering in 6 to 20 ft. Summer white perch concentrate at Deep basin, a prime-rated deep basin around 20 ft. Warm-month bites cluster around early morning. A small spinner rig drifted or a 1/8 oz jigging spoon covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk | Back-bay flat (5 ft) | Small jig + curly tail, Inline spinner (silver) |
| Summer | 6 to 20 ft | dawn | Deep basin (20 ft) | Small spinner rig drifted, 1/8 oz jigging spoon |
| Fall | 6 to 20 ft | midday | Deep basin (20 ft) | Jigging spoon (small), Blade bait |
| Winter | 6 to 20 ft | dusk | Deep basin (20 ft) | Small rattle spoon, Tungsten + spikes |

Turtle Lake is about 20 ft (6 m) deep at its deepest point. The depth chart comes from published agency bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target walleye, yellow perch, smallmouth bass, largemouth bass, rock bass, white perch, bluegill, pumpkinseed, freshwater drum on Turtle Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species listed for the nearest surveyed lakes in the region, filtered to this lake's depth and habitat.
Deep basin is the top-rated area: a deep basin in about 20 ft of water that rates prime for walleye in winter. Scroll up to the map for the complete spot list by species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
