The production trend survey in this area showed about the same number 
of young produced in the trend area. (See Table IV.) The non-breeding and 
unsuccessful breeding segments of the population reacted a little differently this 
year. They did not use the trend area for molting in 1956; hence the lower 
number of adults was seen in the production trend survey. Some areas had poor 
water conditions in 1956 which was reflected by poor production, particularly on 
Hewitt Lake and Wild Horse Reservoir.

The results of the production surveys in the Flathead Valley Unit are 
shown in the following summary. The decrease in goose production was probably 
due to a combination of the heavy out-of-State kill on the local goose population 
and exceptionally late spring in 1956.
