Conclusions 
In view of the near normal weather conditions plus the 
fact that there was little change in the size of the breeding population 
(plus three percent) it is estimated that the fall flight of ducks from 
California will be about the same as in 1956. 
A 25 percent increase in nesting pairs of Canada geese 
and good production which should result in an increase in the total 
fall population of this species. 
NEVADA 
Weather and Water Conditions 
Spring weather throughout the early nesting season was 
generally wet and cold over the bulk of the State's waterfowl nesting 
habitat. This period was characterized by frequent rains and some 
snow in the higher elevations and added materially to the earlier water 
forecast. This condition was particularly significant in the northeastern 
section of the State. Despite the inclement weather, conditions were in 
general not adverse to waterfowlproduction as early brood surveys 
indicate good to excellent production on most trend areas. 
Run-off on the Owyhee River and the Humboldt River in 
northeastern Nevada is forecast to range from 75 to 87 percent of 
normal, All reservoirs were at or near capacity at the start of the 
breeding season. This condition is very favorable to waterfowl pro- 
duction on these areas in that a gradual draw-down for irrigation 
minimizes nest loss due to flooding. 
Streams flowing into the west-central region of Nevada 
from the California Sierras were predicted to flow from 75 to 85 per- 
cent of normal. This flow proved to be adequate in providing for 
capacity or very near capacity water storage for all major lakes, 
reservoirs and marshes affording waterfowl nesting habitat in this 
section of the State. 
Production Data 
Ducks: Production on the reservoir trend areas in north- 
eastern Nevada appears to be comparable or slightly higher than last 
year. Production was up 75 percent last year over the preceding year
