Lake depth chart

6,152-acre lake near Ortonville. The lake tops out around 15 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 the Minnesota DNR survey of 1958, a decades-old survey (the DNR's original lake-survey map). Species by species, here's what the data says the year looks like.
Big Stone Lake's chart carries 66.9 miles of bank — 9 islands included. A development index of 4.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. End to end it runs roughly 24.5 mi, about 4.7 mi across. It sits in Big Stone County. If the bite dies, Barry is 10 mi to the north.
The spring pattern is a shallow one: walleye in 4 to 15 ft. The depth story barely changes: 5 to 15 ft through summer, 5 to 15 ft in winter. The spot to know is Break off the point, a drop-off in about 15 ft of water that rates prime for walleye in fall. 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 | Gravel shoal (3 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 15 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (15 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 15 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (15 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 15 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (15 ft) | Jigging spoon + minnow head, Rattle bait |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Midsummer fish sit out in 5 to 15 ft before dropping to 5 to 15 ft for winter. Spring yellow perch concentrate at Shallow bay flat, a prime-rated weed flat around 3 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.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 15 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season northern pike use the shallows, holding in 2 to 8 ft. Summer is a 5 to 15 ft game here, winter a 5 to 15 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 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.

| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |

| Winter | 5 to 15 ft | midday | Shallow flat (5 ft) | Tip-ups, Large jigging spoon |
Spring largemouth bass on Big Stone Lake hold shallow, usually 2 to 10 ft. They move out to 5 to 15 ft in summer and finish the year down in 5 to 15 ft. 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 and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.

| Winter | 5 to 15 ft chart-limited; documented 15 to 35 ft | midday | Break off the point (15 ft) | Blade bait, Jigging spoon |
In spring, rock bass run shallow here, mostly 2 to 10 ft. Summer pushes them deeper, 4 to 15 ft, and winter fish settle into 5 to 15 ft. Gravel shoal is the standout, a gravel shoal at roughly 3 ft, rated prime for spring rock bass. Time it for the evening. You won't need more than a ned rig (small) or a marabou jig most summer days.

The spring pattern is a shallow one: white bass in 2 to 12 ft. As the season builds they drop to 5 to 15 ft, wintering in 5 to 15 ft. Top water on the chart: Main-lake point, a point in the 6 ft range, prime in fall. Time it for early morning and the evening. Summer baits: a slab spoon or a small topwater (schooling fish) gets it done.
