South Dakota Duck Season 2026-27: Zones, Dates, and Timing

South Dakota hunts four duck zones on three schedules, and the spread is five weeks. Here are the 2026-27 dates, and why the Coteau is finished in early December while the Missouri reservoirs hunt into January.

Updated August 23, 2026. Season dates cite the agency sources listed at the bottom of this page.

2026-27 South Dakota duck season by zone

Low Plains North and Middle

September 26 to December 8, 2026

The earliest opener of any state DuckCast covers, and the earliest close. Both zones run the same dates, so the Coteau and the James valley hunt one schedule.

Low Plains South

October 24, 2026 to January 5, 2027

Opens a month after the north and runs four weeks longer, because the lower Big Sioux and the Missouri confluence hold water after the prairie basins are hard.

High Plains

October 10, 2026 to January 14, 2027

West of the Missouri River, plus the reservoir corridor. The latest close in the state, and the extra days are a federal allocation to the High Plains unit rather than a sign of more birds.

Teal, and the youth season

  • No separate September teal season. Two bonus blue-winged teal during the first nine days of each zone's own season.
  • Youth waterfowl: September 12-13, 2026

Goose seasons are set separately and are deliberately not listed here, because we have not verified those dates against SDGFP and an invented date that looks right is worse than an absent one. Read the goose dates, the daily bag limits and the legal zone boundaries off South Dakota Game, Fish and Parks rather than any summary, this one included. A zone boundary is exactly the kind of detail a summary gets wrong.

Three schedules, three different peaks

These windows come from the same per-region season curves the live DuckCast forecast runs on, so the guide and the product cannot disagree.

Prairie Coteau, Sand Lake, Glacial Lakes, mid James

Peak around November 6, prime October 25 to November 21

Big Sioux corridor and Lewis and Clark

Peak around November 18, prime November 3 to December 3

Oahe, Grand River, Cheyenne River

Peak around November 15, prime November 3 to November 30

Notice the peaks sit within twelve days of each other while the closing dates are five weeks apart. That is the honest shape of it: the birds move through on roughly one schedule, and what differs is how long each part of the state can still hold them afterwards.

Why the west hunts longest, and what that does not mean

The High Plains zone closes on January 14, five weeks after the northeast. It would be easy to read that as five extra weeks of birds. It is not.

Most of those extra days are a federal allocation: the High Plains Mallard Management Unit gets a longer framework than the Low Plains, which is a decision about season length rather than a count of ducks. By mid January the bulk of the mallards are in Nebraska and Kansas.

What is real is smaller and worth knowing. Oahe is a mainstem reservoir kept open by winter releases when every prairie basin around it is locked, so a remnant sits on the river and the tailwaters into January. Our curve carries that as a modest late tail rather than a second peak, which is why a January score out west reads as worth a look and not as November.

South Dakota fills from exactly one direction

South Dakota fills from one state and one state only. Everything arrives down the James and the Missouri out of North Dakota, which means the front that closes the season up there is the same front that starts the best week down here.

That makes the upstream watch unusually simple here and unusually useful. DuckCast tracks 8 North Dakota stations at two latitudes, because a freeze at 48 degrees north is two or three days out and the same freeze at 47 is about half a day, and reads NEXRAD radar after dark to check whether the birds actually flew. One state north, the same front is the end of the season. Here it is the beginning of the best week.

Common questions

What are the South Dakota duck season dates for 2026-27?

South Dakota hunts four duck zones, and because Low Plains North and Middle share dates it comes to three schedules. Low Plains North and Middle run September 26 through December 8, 2026. Low Plains South runs October 24, 2026 through January 5, 2027. High Plains, west of the Missouri River, runs October 10, 2026 through January 14, 2027. There is no separate September teal season; instead each zone allows two bonus blue-winged teal during the first nine days of its own season. Youth waterfowl is September 12-13, 2026. Goose season dates are set separately and are not listed here, so read those off South Dakota Game, Fish and Parks directly.

What are the South Dakota duck zones?

Four: High Plains, Low Plains North, Low Plains Middle and Low Plains South. The High Plains line follows the Missouri River, so as a rough orientation everything west of the river is High Plains and everything east is one of the three Low Plains zones, running north to south. The boundaries are legal descriptions that follow specific rivers and highways, so a county near a line can be split, and that is exactly where a summary like this one will fail you. Confirm yours against the SDGFP zone map before you hunt.

Why does South Dakota have four duck zones?

Because five weeks separate the close in the northeast from the close in the west. Low Plains North shuts on December 8 while High Plains hunts to January 14, and the reason is water rather than latitude: the Prairie Coteau is shallow glacial basins that lock early, and the Missouri mainstem reservoirs stay open on winter releases when everything around them is frozen. A single statewide season would either close the west while birds were still sitting on open river, or hold the northeast open over ice.

When is peak duck migration in South Dakota?

Early to mid November in most of the state, and the DuckCast per-region curves put it at about November 6 across the Prairie Coteau, Sand Lake, the Glacial Lakes and the mid James, around November 18 in the Big Sioux corridor and along the Missouri at Lewis and Clark, and around November 15 through Oahe and the west river country. South Dakota is a staging state rather than a wintering one, so the peak is sharper and earlier than Arkansas or Missouri and the season is largely over by the time theirs is getting good.

Is there a September teal season in South Dakota?

No separate one. South Dakota is a duck production state, and like North Dakota it takes the bonus instead: two extra blue-winged teal on top of the daily limit during the first nine days of each zone's regular season. Because Low Plains North opens September 26, that bonus window is still in September for hunters in the northeast, which is the closest thing the state has to a teal season. Youth waterfowl runs September 12-13, 2026.

Where does South Dakota get its birds from?

One state, almost entirely: North Dakota. Everything arrives down the James and the Missouri, which makes South Dakota unusual among the states DuckCast covers, since Missouri fills from two corridors and Arkansas from several. The practical consequence is that the front closing the season in North Dakota is the same front opening the best week in South Dakota. DuckCast watches eight North Dakota stations at two latitudes for exactly that reason: a freeze at 48 degrees north is two or three days out, and the same freeze at 47 is about half a day.

DuckCast forecasts South Dakota nightly

Regional migration scores built from live weather, the upstream freeze line, crop progress and hunter reports, then checked against NEXRAD radar to see whether birds actually moved after dark. Dates tell you when the season is open; the forecast tells you which mornings inside it are worth burning a vacation day on.
