Upper Bay and Susquehanna Flats Duck Migration Forecast
Cecil and Harford counties at the head of the Bay: the Susquehanna Flats and the first big water below the river. Fresh to barely brackish, and the first of the Bay to ice.
When Upper Bay and Susquehanna Flats peaks
DuckCast’s season model puts the wood duck peak here around mid November. Upper Bay and Susquehanna Flats carries its own season curve rather than sharing Maryland'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 the Maryland Department of Natural Resources.
What DuckCast watches upstream of Upper Bay and Susquehanna Flats
5 upstream stations feed this region's freeze line: Harrisburg, Williamsport, Wilkes-Barre, Binghamton, Montezuma. When those stations ice over, the score here starts climbing before anything changes in the local sky.
Locations stay generalized
Hunter reports for Upper Bay and Susquehanna Flats are always shown at the region level. DuckCast never collects or displays exact coordinates, so filing a report here never burns a spot.
