Conclusions ~ In view of the small decrease in breeding population in 
Northern Alberta and Northwest Territories this year it is anticipated that 
there will be a slight reduction in the fall flight from these areas as compared 
to last year. 
ALASKA 
Weather and Water Conditions - The winter in Alaska was more mild 
and open than usual, Polar air masses were weak, Water levels during the 
spring and summer were unusually low and runoff has been light. Although 
some shallow lakes are drying up, there is no shortage of suitable waterfowl 
habitat, No unseasonable storms or cold weather developed and, in general, 
it can be said that conditions were favorable for waterfowl production, 
Breeding Population Index - The breeding population appeared to be slightly 
up in some areas and slightly down in others, In general, the breeding 
- population in Alaska seemed to be about the same as last year, 
Production Index ~ Brood production in all areas studied seemed to be about 
the same as last year, 
Conclusions = The fall flight from Alaska will be about the same as last year,
