Water temperature, river discharge, and adult sockeye salmon migration observations in the Babine watershed, 1946-2014: Fs97-4/3053E-PDF

Historical meteorological and hydrological data were assembled to review the influence of changes in these environmental factors on patterns of adult Sockeye migration in the Babine River, British Columbia. Regional air temperature data collected from Environment Canada meteorological stations were statistically related to intermittent water temperature time-series (2003-2014) recorded at the Babine fish fence to hind-cast daily water temperature in Babine River for 1910-2014. Flow data from two hydrometric stations in the Babine watershed were statistically-related to construct a continuous daily discharge time-series for 1945-2014. A stratified categorical frequency analysis of daily migration rates versus water temperature and flow conditions, lagged 0-7 days earlier, was used to discern the most likely combination of threshold values for temperature, discharge and associated time lags contributing to daily fence count variation.
