Manager's update

Week in Review

Sept. 13–19

Weather

Temperatures remained well above average for mid-September. Daytime highs were in the mid- to upper 70s. Winds were calm to start the week, with northeast winds dominating toward the end. The week was precipitation-free, further amplifying the drought conditions we are currently experiencing.

Waterfowl Abundance

Refuge numbers continue to build as we move into fall. Teal and mallards make up the majority of the current species. Birds are beginning to venture out of the refuge as water is added to the hunting zones.

Hunting Conditions

North:
Zones 2–3: Corn cover averages 8 feet tall; water depth varies in Zone 3 (6–8 inches), with Zone 2 being dry.
Zones 4–6: Corn cover averages 8 feet tall; water depth varies 4–6 inches, with Zone 4 being the driest at the north end.
Zone 7: Corn cover 6–8 feet tall; zone is dry.
Zone 8: Corn cover 5–8 feet tall, planted in two blocks; shortest on the north end. Water depth varies 6–12 inches.

Zone 23: Corn cover averages 8 feet tall with some thin spots on the south end; sheet water at the south end.
Zone 24: Sparse corn cover 4–7 feet tall; 5 feet tall at the blind. South of the blind, no corn. Water depth varies 4–10 inches.
Zone 25: Corn cover averages 8 feet tall with some thin spots; water depth varies 4–8 inches.

Marshes:
The north marsh will remain at low pool or be drawn down to complete a winter burn in 2025–26. Water has been added to the east marsh. All marshes will be lower than full pool levels due to drought and falling Great Lakes water levels.

Hunter Numbers

Zones are currently available on a first-come, first-served basis for the early Canada goose season. For the week, we had eight hunter trips.

Waterfowl Harvest

Hunters harvested two Canada geese this week.

What to Expect This Week

Temperatures are expected to remain above normal for this time of year. The week starts off with rain in the forecast, gradually clearing as the week progresses. Highs are expected to be in the mid- to upper 70s. Winds are expected to be light for most of the week.
