In view of a change in sampling procedure this year, the 1955 data were 
reviewed and portions were selected which were thought to be reasonably 
comparable with 1956. A re-calculation of the 1955 indices using these data 
resulted in a revised population index of 79, 787 birds for the Cariboo, 
Chilcotin, and Prince George areas. On this basis, a decrease of 21 per= 
cent between 1955 and 1956 is indicated. Since it is doubtful that our 
sampling is intensive enough to measure changes as small as 20 percent, we 
are of the opinion that a ''no change'' status exists throughout the areas 
surveyed. . 
Production Indices - 
Midsummer counts on sample lakes in Cariboo and Kamloops regions 
show waterfowl numbers to compare favorably with those of last year. 
Water conditions are good and production is forecast to be equal to past 
several years. 
Conclusions - 
The fall flight from,British Columbia should be about the same as last 
year. | 
OREGION 
Weather and Water Conditions - 
An abundance of rain and snow fell throughout the State during the 
winter. This along with an unusually large amount of rain early in the 
spring left all marshes and potholes full and in excellent condition for water- 
fowl production. 
Production Data - 
Canada goose production in Oregon is about the same as for 1955. 
Samples at Summer Lake and in the Klamath Basin were nearly the same. 
In Warner Valley rising waters flooded many nests, leaving production 
about 60 percent of normal.
