Five seasons of area totals.

What MDC published for each managed area, 2021-2022 through 2025-2026. Whole-area numbers only. MDC does not publish blind or pool history, so this is each area as a whole, not a spot within it.

Grand Pass by season

Season	Days	Ducks	Hunters	Per hunter
2021-2022	57	16,300	5,177	3.15
2022-2023	57	13,154	4,333	3.04
2023-2024	61	19,406	5,843	3.32

2025-2026	60	10,236	5,066	2.02

Per hunter is total ducks divided by total hunters for the season. 3 posted records are left out because MDC posted more than one for the same day or gave no hunter count.

2021-2022 day by day

Every row shares the same dates, so read straight down. Gaps are days MDC did not report, not zero-bird days. Tap a season in the table above to switch.

By morning temperature, all five seasons

Temp	Days	Ducks	Hunters	Per hunter
Below 25°F	30	4,603	2,616	1.76
25 to 35°F	104	27,862	9,949	2.80
35 to 45°F	88	24,665	7,789	3.17
45 to 55°F	53	13,127	4,375	3.00
55°F and up	21	4,360	1,321	3.30

By morning wind, all five seasons

Wind	Days	Ducks	Hunters	Per hunter
Under 5 mph	65	13,800	5,929	2.33
5 to 10 mph	129	31,878	11,034	2.89
10 to 15 mph	78	22,293	7,148	3.12
15 mph and up	24	6,646	1,939	3.43

By river trend, all five seasons

River	Days	Ducks	Hunters	Per hunter
Falling	62	13,713	5,341	2.57
Steady	206	55,395	18,315	3.02
Rising	28	5,509	2,394	2.30

Falling or rising means the river moved 10% or more over the three days before the posted date. River is Missouri River at Glasgow, MO, about 25 miles from the area. It is a river reading, not the water level in any pool, and MDC controls pool water with pumps and gates.

These tables describe past days. They are not a forecast, a small day count means a shaky number, and one thing lining up with another does not mean it caused it. Temperature and wind are from Marshall CAA Airport, about 14 miles away, for sunrise to mid-morning on MDC's posted date.
