Hunting conditions

This past week saw hunting conditions switch from open water conditions to freezing up. Water levels on rivers and access channels within the game area are low and have begun freezing up. Launching boats may be hazardous.
Units 9-14 and 1-4 fields strips of corn. The huntable corn strips in 9-14 and 1-4 will vary from 6ft to 8 feet in height. 9-14 have been flooded and are about 16 inches deep with water. Units 1-4 are flooded, and water depth is about 20 inches.

Wahl Road Marsh unit water levels are full pool and have begun freezing up.

Zone 29 has had some marshmaster mowing performed before season to create openings. Water levels are at full pool. Access channel to the SW pullover for 29 has very low water levels. To hunt zone 29, it is recommended that duck hunters pull the dike at the 30s and motor to the 29 pullovers north of zone 36.
