Air temperature data, adjusted and homogenized for climate analyses, were obtained for a regional meteorological station (at Williams Lake), and statistically related to intermittent water temperature time-series (spanning 1996-2012) in the Chilko and Chilcotin rivers to hind-cast daily mean water temperature for 1940-2012 at key sites along the migration route. Flow data from two hydrometric stations in the watershed were statistically-related to construct continuous daily discharge time-series for 1927-2012 at the same sites. A stratified categorical frequency analysis of daily water temperature and flow levels versus standardized daily migration lagged 0-20 days earlier was used to discern the most likely combination of threshold values for temperature, discharge, and time lag contributing to daily migration rate variation. The resulting critical thresholds were applied in exceedance analyses to review trends in flow & temperature events pertinent to Chilko Sockeye migration"--Abstract, p. v. |
