Table II shows that of 282 water sites censused twice during these surveys, 
72 percent showed no change or more water during the second coverage as compared 
to the first coverage, Late June and early July experienced below normal precipita- 
tion. However, plenty of water remained for waterfowl] production.

Breeding Population Trends 
V;isconsin has as its principal breeding ducks, the blue-winged teal, mallard, 
black duck, wood duck, and ringneck. All of these species demonstrated an increase. 
in breeding pairs except the wood duck, with the blue-winged teal increasing its status 
over 1952 by 200 percent (Table III). Table V summarizes the breeding pair and 
production trends for the period 1951-1953,
