Last week in review
Nov. 3–10, 2025
Weather
From Monday, Nov. 3 through Thursday, Nov. 6, skies were clear and sunny with high temperatures in the mid to upper 50s. Nighttime lows hovered around the freezing mark, dipping into the low 30s. On Friday, Nov. 7, skies turned cloudy with west winds and a high of 50 degrees. Saturday morning reached a high of 43 degrees before temperatures fell throughout the day, with an overnight low of 35. Sunday, Nov. 9 brought snow all day with north winds, a high of 37, and a low of 32. Monday, Nov. 10 saw high temperatures barely reaching 30 degrees and an overnight low of 21.
Waterfowl abundance
The refuge count was conducted on Nov. 10. Ice had begun forming in the refuge, which contributed to a decrease in bird numbers. It is expected that numbers will rebound as seasonal weather returns and ice breaks up. The latest count recorded 12,575 birds in the refuge, including:
Mallards: ~7,500
Wigeon: 2,000
Gadwall: 1,000
Pintail: 1,000
Black duck: 400
Green-winged teal: 400
Geese: 1,250
Hunting conditions
Water levels on rivers and access channels within the game area are low but manageable. Short-shaft outboards may experience difficulty in some areas. Managed units are at prescribed water levels and access channels should be navigable.
Units 9–14 and 1–4: Full of corn, harvested at the end of October. Corn strips range from 6 to 8 feet tall. Units 9–14 are flooded to about 15 inches; units 1–4 are flooded to about 20 inches.
30s: Soybeans with strips of planted corn. Soybeans have been harvested and the area is flooded. Corn ranges from 6 to 9 feet tall. Water depth varies from 12 to 24 inches.
Zones 6–8: Corn strips 5.5 to 6.5 feet tall with moist soil in between. Blinds are available in zones 6 and 7. Water depth is 15 inches.
40s (units 39–46): Corn strips range from 5.5 to 8 feet tall with moist soil between. Water depth ranges from 9 inches in the north to 18–24 inches in the southern zones.
