| Abstract/Description or Keywords | The tributaries of the Fraser River provide spawning habitat to large numbers of sockeye salmon that are known to be susceptible to both high flow and high temperature conditions. Twenty semi-weekly 10 day forecasts for flow and water temperature were made for the 2004 migration season (July 1-Sept. 15). The RMS error for daily average temperature was 0.86°C. The RMS error for daily average flow was 10.4%. The accuracy of the flow forecasts, the temperature forecasts and the weather forecasts (used to force the temperature forecast model) is shown to decrease with the length of the forecast. The instrumentation used to establish initial conditions for the models and for forecast validation is described. The report concludes with set of recommendations for improving the river forecast models and their operation. |
