Waseca had almost 14" of rain in 2 days time. Heavy(4"+) in many places in southern MN. Maple Grove had 10.39" in 1 spot last night. NE Iowa had major rains and flooding too. Eau Claire area of WI is flooded too.
In a nutshell, the ducks could be anywhere with all the standing water where ever they had heavy rains.
So will the rains hurt where you would normally hunt?
Heck I bet some will not even go due to flooded basement, etc.
I bet MLDS will not being going as he and his crew likely are in Corcoran and MG area helping residents with their flooded basements, I bet he'll be super busy for the next 2 weeks.
BTW, more heavy rains are possible for SAT PM
The map below are rainfall amounts as of 3 in the morning--it was still raining in southern and SE Mn till daybreak.
