1,046-acre lake near Brant Lake. The lake tops out around 14 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. The rest of this page walks each species through its year, using the map's own scoring.
Traced from the shoreline, Brant Lake runs 1,047 acres with 7.4 miles of edge. The shoreline is moderately structured (index 1.6) — enough points and pockets to pattern. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Call it 2.5 mi long by 1.2 mi wide at the broadest reach. The water lies in Lake County. The nearest mapped water is Long Lake, 3 mi to the west.
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 4 to 14 ft, and by winter most fish are in 4 to 14 ft. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.
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 | 4 to 14 ft chart-limited; documented 10 to 30 ft | dawn | open water | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 14 ft chart-limited; documented 12 to 35 ft | midday | open water | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 14 ft chart-limited; documented 15 to 35 ft | midday & dawn | open water | Tungsten jig + spikes, Rattle spoon (small) |
The spring pattern is a shallow one: crappie in 2 to 8 ft. As the season builds they drop to 4 to 14 ft, wintering in 4 to 14 ft. Time it for early morning and the evening. Summer baits: a jig trolled/spider-rigged or a small crankbait (trolled) gets it done.

Spring puts bluegill in skinny water — 1 to 6 ft is the zone. As the season builds they drop to 4 to 14 ft, wintering in 4 to 14 ft. Warm-month bites cluster around early morning and the evening. A small sponge spider (fly) or a micro tube jig covers the summer program.

The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 4 to 14 ft, wintering in 4 to 14 ft. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

When the water first warms, walleye slide up into 4 to 14 ft. There's no big seasonal slide here — summer means 4 to 14 ft, winter 4 to 14 ft. The feeding windows run the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.

Start shallow in spring: largemouth bass sit in 2 to 10 ft that time of year. Summer pushes them deeper, 4 to 14 ft, and winter fish settle into 4 to 14 ft. Warm-month bites cluster around early morning and the evening. Throw a texas-rigged 10" worm or a deep-diving crankbait until the fish tell you otherwise.

Brant Lake is about 14 ft (4 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, largemouth bass, brown bullhead on Brant 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.
