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.

Ducks per hunter: 2.2. Duck species: unavailable. Location kill-board records: unavailable for this area and date.

Goose components (CG / SBG / WFG; group names inferred from source field codes): CG: 1 · SBG: 1 · WFG: 0. These are separate from the duck count.

Historical weather observation · tentative report-date match: 28.4°F mean; 6.8 mph mean wind. Station USW00013991; 144 observations. Rainfall: unavailable (incomplete observations).

Archived forecast guidance · tentative date match: GFS MOS (MAV) via NWS/NCEP via IEM archive; station KMHL; issued 2025-01-03T06:00Z for 2025-01-03T15:00Z–2025-01-03T15:00Z. 25°F; 6 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.
