MISSISSIPPI FLYWAY 
MINNESOTA 
Weather and Water Conditions 
During May, dry conditions were very evident in the southwest 
sections of Minnesota. 
Moderate to heavy rains occurred in late May and June in both 
the Northwest and Southwest strata. In the central sections of Minnesota, 
water was available although levels were low in many lakes. However, 
steep banks, great depth, lack of vegetation and timber do not lend them- 
selves. to good areas for reproduction for some species of waterfowl.
