Where Southwest Coastal Marsh is
Southwest Coastal Marsh is drawn from 2 parishes in Louisiana: Cameron and Vermilion. Those are the parishes its shape on the DuckCast map is built from, so a hunter in any of them reads this region’s score.
When Southwest Coastal Marsh peaks
DuckCast’s season model puts the pintail peak here around mid December. This follows the statewide pintail curve. 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.
What DuckCast watches upstream of Southwest Coastal Marsh
3 upstream stations feed this region's freeze line, nearest first: El Dorado, AR, about 235 miles north, Texarkana, TX, about 255 miles north and Pine Bluff, AR, about 305 miles north. When those stations ice over, the score here starts climbing before anything changes in the local sky.
Radar over Southwest Coastal Marsh
Each morning DuckCast reads the night’s NEXRAD data from KLCH, the National Weather Service radar at Lake Charles, about 25 miles northwest of the region’s weather point. That is close enough for the radar to sample the air over the region itself. 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 Southwest Coastal Marsh are always shown at the region level. DuckCast never collects or displays exact coordinates, so filing a report here never burns a spot.
