Kansas Duck Migration Forecast

Where KS birds come from

Kansas fills from one state, and it is one DuckCast already scores. That makes four in a row: a front can be followed from prairie Canada through North Dakota, South Dakota and Nebraska to the night it drops mallards onto Cheyenne Bottoms. The eight Nebraska stations sit at two latitudes because the same freeze is two or three days out from central Nebraska and about half a day out from the state line.

DuckCast watches Nebraska for the freeze and snow that start birds moving, then reads NEXRAD after dark to see whether they actually flew. The upstream picture is why a score can rise here before anything changes in your own sky.

The 9 regions we score in Kansas

Every region gets its own daily score. Reports are generalized to the region, so nobody burns your spot.

• Cheyenne Bottoms

  Forty-one thousand acres of shallow marsh in the Smoky Hills, plus the Kanopolis and Wilson country east of it. The best pintail water in Kansas, and the first to lock.

• Quivira and the Rattlesnake

  Salt marsh on Rattlesnake Creek down through the Reno and Pratt sand prairie. Holds three weeks past Cheyenne Bottoms and hunts a different zone.

• North Central Reservoirs

  Glen Elder, Kirwin, Webster and Lovewell across the Solomon and Republican valleys. Big water that fills late in December and freezes before the east does.

• Northeast Reservoirs and the Kaw

  Tuttle Creek, Milford and Perry, the Kansas River through Topeka and the Missouri along the Doniphan bluffs. The deepest water in the state and the last of it to go.

• East Central Lakes

  Clinton, Melvern, Pomona and John Redmond, with the Marais des Cygnes bottoms running east to the Missouri line. Reservoir roosts and creek-bottom feeds.

• Southeast Timber

  Neosho and Verdigris bottoms, Elk City, Fall River and Big Hill. Flooded timber and backwater that stays open when the reservoirs skim, and the last good water in Kansas.

• South Central and the Arkansas

  Cheney and El Dorado either side of Wichita, the Arkansas River running southeast, and the Slate Creek marshes down toward the Oklahoma line.

• Southwest Playas

  Playa basins scattered through the feedlot country, the upper Arkansas through Dodge City, and the Cimarron grassland in the far corner. Good when the basins fill and quiet when they do not.

• Northwest High Plains

  Cedar Bluff and Sebelius with scattered playas between them, in the driest corner of the state. Thin country that hunts on whatever water is left.

Common questions about Kansas

When does the duck migration peak in Kansas?

DuckCast's season model puts the mallard peak in Kansas around mid November to late December. The timing is not uniform across the state: the model peaks Cheyenne Bottoms around mid November and Southeast Timber around late December, which is why each region carries its own season curve rather than sharing one. That is a modelled typical curve, not a prediction for any single year: the actual push depends on cold fronts and freeze-up upstream, which is what the daily score tracks. Always confirm season dates with the Kansas Department of Wildlife and Parks.

Where do Kansas's ducks come from?

Kansas fills from one state, and it is one DuckCast already scores. That makes four in a row: a front can be followed from prairie Canada through North Dakota, South Dakota and Nebraska to the night it drops mallards onto Cheyenne Bottoms. The eight Nebraska stations sit at two latitudes because the same freeze is two or three days out from central Nebraska and about half a day out from the state line. DuckCast reads conditions across Nebraska and watches for the freeze that pushes birds south, so a KS hunter sees the push building before it arrives.

Which parts of Kansas does DuckCast cover?

All 9 regions: Cheyenne Bottoms, Quivira and the Rattlesnake, North Central Reservoirs, Northeast Reservoirs and the Kaw, East Central Lakes, Southeast Timber, South Central and the Arkansas, Southwest Playas, Northwest High Plains. Each gets its own daily score. Locations are always region-level; DuckCast never collects or shows exact hunting spots.

Does DuckCast use weather radar in Kansas?

Yes. DuckCast decodes raw NEXRAD Level II volumes from the 5 National Weather Service radar sites covering Kansas, and reads how much bird mass lifted off after sunset and which way it tracked. Separately, 8 upstream weather stations across Nebraska feed the freeze line; those are weather reports, not radar. Radar sees every bird in the air, not just ducks, so read it as evidence that a migration happened rather than a duck count.

When is the best time to duck hunt in Kansas?

For mallard, the modelled peak in Kansas falls around mid November to late December, and the strongest hunting is usually the weeks on either side of it. The timing is not uniform across the state: the model peaks Cheyenne Bottoms around mid November and Southeast Timber around late December, which is why each region carries its own season curve rather than sharing one. Inside that window the best mornings follow a cold front with a hard freeze across Nebraska and a north wind behind it, which is exactly what the daily KS score measures. Season dates are set by the Kansas Department of Wildlife and Parks, and the peak is a modelled typical year rather than a promise about this one.

Where can I find a Kansas waterfowl report?

Kansas Wildlife and Parks publishes the official Kansas regulations and, during the season, survey counts and reports, so start there for anything legal. DuckCast adds a daily migration score for each of the 9 KS regions, built from live weather, the freeze across Nebraska, crop progress and hunter reports, and each morning it reads NEXRAD radar to say whether birds actually moved over the region after dark. Hunter reports filed in the app are generalized to the region, never to a spot.
