Conclusions - 
In view of the fact that there were both increases and decreases in brood 
production, it is estimated that the fall duck flight from Idaho will be about the 
same as in 1955. It is estimated that there will be a small increase in the flight 
of Canada geese. 
UTAH 
Weather and Water Conditions - 
The spring run-off was normal for all of Utah except some limited water - 
fowl breeding areas in southern Utah. Most of Utah's reservoirs, ponds, and 
marshes had a good supply of water. Temperatures were slightly above normal, 
which probably started nesting earlier than usual. Water and weather conditions 
were ideal during the nesting and brood season.
