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.

River-flow charts & limitations
These USGS river measurements are regional proxies, not hunting-pool depth. Their dates are tentatively matched to MDC report dates. Separate gauges retain their own units and series.
