Conclusions - 
It would appear that state-wide there was a definite increase in wood 
duck populations with a decrease in mallards, blacks and blue-winged teal. 
Over-all, it is estimated that the fall flight from Ohio will be similar to 1954.

Weather and Water Conditions - 
April.and May precipitation in the lake and pothole region was a half 
inch to 11/2 inches below normal. This deficiency was not considered 
detrimental to brood production, as unprecedented rains of October 1954, and 
the near normal precipitation during the winter months had left the breeding 
habitat in good condition. By the first of July 1955, some of the wetland study 
areas were beginning to show the effects of deficient rainfall but general and 
frequent rains between July 5 and July 15 restored them to normal levels.
