147-acre lake near Yankton County. The lake tops out around 29 ft. The depth chart comes from South Dakota Game, Fish and Parks bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Species by species, here's what the data says the year looks like.
The outline encloses 147 acres, worked by 3.8 miles of shoreline. That shoreline is heavily fingered (development index 2.2) — bays, points and pockets everywhere, which multiplies the fishable edge. Littoral water — the productive band under ~15 ft — makes up 90% of this chart. Tip to tip the water measures near 1.4 mi with a 0.4-mi widest point. It sits in Yankton County. Its nearest charted neighbour, Beaver Lake, is 10 mi to the west.
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Warm water sends them out to 9 to 29.2 ft; cold water stacks them in 9 to 29.2 ft. Fish it in early morning and you'll meet the bite. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.
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 | 3 to 12 ft | midday & dawn | open water | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 9 to 29.2 ft chart-limited; documented 10 to 30 ft | dawn | open water | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 29.2 ft chart-limited; documented 12 to 35 ft | midday | open water | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 29.2 ft chart-limited; documented 15 to 35 ft | midday & dawn | open water | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for crappie tight to the bank in 2 to 8 ft. They move out to 10 to 25 ft in summer and finish the year down in 9 to 29.2 ft. Best bite is early morning and the evening. A jig trolled/spider-rigged or a small crankbait (trolled) is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | 1/16 oz jig + tube, Curly-tail grub |
| Summer | 10 to 25 ft | dawn & dusk | open water | Jig trolled/spider-rigged, Small crankbait (trolled) |
| Fall | 8 to 20 ft | dawn | open water | Jig + minnow combo, Small swimbait (1.5-2") |
| Winter | 9 to 29.2 ft chart-limited; documented 15 to 35 ft | midday | open water | Tungsten jig + soft plastic, Tiny jigging spoon |
When the water first warms, bluegill slide up into 1 to 6 ft. By summer they slide out to 4 to 15 ft, and by winter most fish are in 10 to 25 ft. In summer the feeding windows fall in 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 | open water | 1/32 oz jig + micro plastic, Tiny popper (evenings) |
| Summer | 4 to 15 ft | dawn & dusk | open water | Small sponge spider (fly), Micro tube jig |
| Fall | 6 to 18 ft | midday | open water | Micro jig + waxworm, Small spoon tipped |
| Winter | 10 to 25 ft | midday | open water | Tungsten ice jig + plastic, Tiny spoon |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Best bite is early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | open water | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | open water | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | open water | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | open water | Tip-ups, Large jigging spoon |
Spring puts walleye in skinny water — 4 to 15 ft is the zone. Warm water sends them out to 9 to 29.2 ft; cold water stacks them in 9 to 29.2 ft. Plan around the evening and early morning in the warm months. A crawler harness on bottom bouncer or a deep crankbait (trolled) covers the summer program.

Marindahl Lake is about 29.2 ft (9 m) deep at its deepest point. The depth chart comes from South Dakota Game, Fish and Parks bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Anglers target yellow perch, crappie, bluegill, northern pike, walleye on Marindahl Lake. This isn't a survey of the water — none is published for it — but an informed estimate from the species common to the region, narrowed by this water's depth, size and each species' range.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Marindahl Lake is regulated by the South Dakota Game, Fish and Parks. Check the official South Dakota regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
