Post Oak Savannah Duck Migration Forecast

Where Post Oak Savannah is

Post Oak Savannah is drawn from 24 counties in Texas: Bastrop, Bell, Bosque, Brazos, Burleson, Coryell, Falls, Fayette, Freestone, Grimes, Hamilton, Hill, Lee, Leon, Limestone, Madison, McLennan, Milam, Navarro, Robertson, Travis, Walker, Washington and Williamson. 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 Post Oak Savannah peaks

DuckCast’s season model puts the pintail peak here around mid January. 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 Post Oak Savannah

In DuckCast’s season model, the species that can score highest in Post Oak Savannah are green-winged teal, blue-winged teal and gadwall. Against the state as a whole, it expects fewer mallards in Post Oak Savannah.

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 Post Oak Savannah

3 upstream stations feed this region's freeze line, nearest first: Hugo, OK, about 215 miles north, Ardmore, OK, about 220 miles north and McAlester, OK, about 275 miles north. When those stations ice over, the score here starts climbing before anything changes in the local sky.

Radar over Post Oak Savannah

Each morning DuckCast reads the night’s NEXRAD data from KFWS, the National Weather Service radar at Fort Worth, about 115 miles north of the region’s weather point. That is well outside the region, so treat the radar reading as area context rather than a measurement of this ground. Radar sees every bird in the air, not only ducks, so it confirms or questions the score rather than moving it.

Locations stay generalized

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