When Cheyenne River and the Hills peaks
DuckCast’s season model puts the mallard peak here around mid November. Cheyenne River and the Hills carries its own season curve rather than sharing South Dakota's statewide one, because the timing here genuinely differs from the rest of the state. 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 Cheyenne River and the Hills
3 upstream stations feed this region's freeze line: Dickinson, Williston, Bismarck. When those stations ice over, the score here starts climbing before anything changes in the local sky.
Locations stay generalized
Hunter reports for Cheyenne River and the Hills are always shown at the region level. DuckCast never collects or displays exact coordinates, so filing a report here never burns a spot.
