845-acre lake near Otter Tail County. The lake tops out around 30 ft. The depth chart comes from Minnesota Department of Natural Resources bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from a DNR lake survey. Species by species, here's what the data says the year looks like.
South Turtle maps at 845 acres behind 9.6 miles of shoreline. An index of 2.3 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. The shallow band under 15 ft claims about 72% of the surface — that's where the groceries are. End to end it runs roughly 2.3 mi, about 1.1 mi across. It sits in Otter Tail County. Fiske sits 1 mi south — the closest neighbouring chart.
The spring pattern is a shallow one: walleye in 4 to 15 ft. Midsummer fish sit out in 9 to 30 ft before dropping to 9 to 30 ft for winter. The spot to know is Deep basin, a deep basin in about 30 ft of water that rates prime for walleye in winter. Plan around the evening and early morning in the warm months. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) gets it done.
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 | 4 to 15 ft | dusk & dawn | Break off the point (4 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 9 to 30 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Deep basin (30 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 9 to 30 ft chart-limited; documented 12 to 40 ft | dusk & night | Deep basin (30 ft) | Jigging rap, Jig + big minnow |
| Winter | 9 to 30 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (30 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 10 to 30 ft before dropping to 9 to 30 ft for winter. Fall yellow perch concentrate at Deep basin, a prime-rated deep basin around 30 ft. Fish it in early morning and you'll meet the bite. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is an 8 to 20 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 1 ft, prime for spring. Best bite is early morning and the evening. Tie on a bucktail or a weedless spoon over cabbage and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (4 ft) | Bucktail, Weedless spoon over cabbage |

| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
Spring largemouth bass on South Turtle hold shallow, usually 2 to 10 ft. They move out to 8 to 20 ft in summer and finish the year down in 9 to 30 ft. Put Shallow bay flat first on the milk run — a weed flat near 1 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.
