Coverage, calculations & collection dates

Totals use comparable reports. Per hunter = summed ducks ÷ summed hunters. Population surveys are not harvest counts. Collected Oct 13, 2026; the latest advertised and current seasons are checked daily; older archives retain their original collection dates. Older seasons before 2021–22 have harvest only; weather, forecasts and river matches are unavailable in this package.

Archived forecast guidance · tentative date match: GFS MOS (MAV) via NWS/NCEP via IEM archive; station KMHL; issued 2024-01-05T06:00Z for 2024-01-05T15:00Z–2024-01-05T15:00Z. 30°F; 5 knots; 1 forecast point(s). GFS MOS is statistical guidance for the station, not the NWS public forecast hunters read. Issue time is the nominal cycle time; public availability lagged ~4h, so only cycles issued >=6h before window start are used. Valid times are the 3-hourly points inside the assumed hunt window.
