Coverage, calculations & collection dates

Totals use comparable reports. Per hunter = summed ducks ÷ summed hunters. Population surveys are not harvest counts. Collected Oct 31, 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 2025-12-31T06:00Z for 2025-12-31T15:00Z–2025-12-31T15:00Z. 29°F; 3 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.

River flow · tentative date match: USGS-06906500: 30,500 ft^3/s; regional_proxy; daily_mean (calendar day, gauge local time). USGS-06909000: 31,100 ft^3/s; regional_proxy; daily_mean (calendar day, gauge local time). These readings do not establish pool depth or access.
