From data collected at McClinton creek, Masset inlet, British Columbia, as a result of a comprehensive programme of investigation on the pink salmon, Oncorhynchus gorbuscha, a positive significant mathematical correlation is demonstrated between numbers of fish migrating from the sea to the stream each day and both the maximum daily water height in the creek and the daily rainfall in the area. A positive significant correlation also exists between the maximum water height and the rainfall. From available records no co-variation between numbers of migrants and changes in temperature can be shown.
