PACIFIC FLYWAY 
Conclusions - 

In summary, it can be said that, although a cold, late spring 
retarded the cycle of breeding activities, waterfowl production will 
approximate the level of the last two years. 
CALIFORNIA 
Weather and Water Conditions - 
The over-all rainfall in Central Valley was normal for the 
1954-55 season. However, most of the winter was dry, so that it took 
heavy rains to bring precipitation up to average. Parts of Northeastern 
California were extremely dry and some waterfowl areas, such as Horse 
Lake, and Honey Lake were either dry or in critical condition. 
Breeding Population Indices - 
A comparative summary of nesting pairs of waterfowl fora 
five- “year period is shown in Table 1.
