From this information we can see very little change in the 
number of wood ducks in Michigan 
Population Ind:ces 
The brood survey comparisons follow:

Broods were fewer compared to th past few years but 
Similar to the past eight-year average, The number of young per brood 
was next to the lowest in the eight-year average and bachelor birds 
remained equal to the average for the vears recorded. 
Conclusions 
Waterfowl production in Michigan for 1957 was comparable 
to the past eight-year average but slightly below that of last year. 
It seems likely that there has been little change in the 
number of wood duck in the State.

Weather and Water Conditions 
This was an exceptionally wet spring with intermittent 
flooding common on most streams throughout the State. Inland lakes, 
ponds and streams carried a higher level of water than any spring during 
the past five years. Flooding was common even during the first two 
weeks of July when water level normally begin to recede rather rapidly.
