When Prairie Coteau peaks

DuckCast’s season model puts the mallard peak here around early November. This follows South Dakota's statewide curve; Prairie Coteau hasn't needed a curve of its own. 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 South Dakota Game, Fish and Parks.

What DuckCast watches upstream of Prairie Coteau

3 upstream stations feed this region's freeze line: Grand Forks, Fargo, Devils Lake. When those stations ice over, the score here starts climbing before anything changes in the local sky.

Locations stay generalized

Hunter reports for Prairie Coteau are always shown at the region level. DuckCast never collects or displays exact coordinates, so filing a report here never burns a spot.
