Canada Geese-Missouri River 



Four years of Canada goose production data have now been 

 collected on the Missouri River. In 1979, as in 1978, the river 

 was surveyed from the Carter ferry to Robinson Bridge, a total 

 of 16 3 miles. The 1976 survey was conducted from the Carter 

 ferry to the mouth of the Marias River and from Coal Banks Land- 

 ing to Robinson Bridge. In 1977, the survey was from the Carter 

 ferry to the PN ferry. A total of 447 nests was located over 

 the 4 years. Data on nest success, production, and nest site 

 selection were reported on for each year in the 1976, 1977, and 

 1978 job progress reports.
