Where West Branch and the Central Valleys is

West Branch and the Central Valleys is drawn from 10 counties in Pennsylvania: Centre, Clinton, Columbia, Juniata, Lycoming, Mifflin, Montour, Northumberland, Snyder and Union. Those are the counties its shape on the DuckCast map is built from, so a hunter in any of them reads this region’s score.

When West Branch and the Central Valleys peaks

DuckCast’s season model puts the wood duck peak here around mid October. The timing follows the statewide curve; what differs here is how many birds the model expects, below. 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 state wildlife agency, linked below.

Which birds the model expects in West Branch and the Central Valleys

In DuckCast’s season model, the species that can score highest in West Branch and the Central Valleys are wood ducks, Canada geese and mallards. Against the state as a whole, it expects fewer snow geese, wigeon, gadwall, blue-winged teal and Canada geese in West Branch and the Central Valleys.

Those weights come from harvest records, survey counts and the kind of water, not from a count taken here each season. They cap how high each species’ score can climb; the weather still has to bring the birds.

What DuckCast watches upstream of West Branch and the Central Valleys

6 upstream stations feed this region's freeze line, nearest first: Binghamton, NY, about 105 miles northeast, Jamestown, NY, about 125 miles northwest, Montezuma NWR, NY, about 140 miles north, Buffalo, NY, about 155 miles northwest, Iroquois NWR, NY, about 155 miles north and Cape Vincent, NY, about 220 miles north.

Radar over West Branch and the Central Valleys

Each morning DuckCast reads the night’s NEXRAD data from KCCX, the National Weather Service radar at State College, about 40 miles west of the region’s weather point. That puts the radar just outside the region, near enough to see birds lifting off and passing close by. Radar sees every bird in the air, not only ducks, so it confirms or questions the score rather than moving it.
