Summary 
The waterfowl migration and breeding ‘schedule in Manitoba averaged two weeks 
later than usual due to a late break-up and a cold, wet spring. A tremendous run-off 
resulted in a super-abundance of surface water. Low evaporation rates and frequent 
rains permitted most potholes to remain full throughout the summer. 
In southern Manitoba an increase in breeding ducks approximating 15 percent 
was recorded. This was off-set, however, by reduced numbers further north, All parts 
of Manitoba considered, the trend in breeding stock was downward. 
In southern Manitoba, despite increased breeding numbers, production dropped 
below the 1949 level. Northern Manitoba also apparently fared badly in producing water- 
fowl. For the Province as a whole, the trend was downward. 
As a part of the breeding ground survey, 7,135 ducks were banded.
