| Abstract | Temperature data from above and below the Cougar Dam collected by the U.S. Geological Survey prior to the construction of the temperature control structure was analyzed to determine how the di®ering temperature regimes a®ect the growth and survival of threatened spring- run Chinook salmon. An ARIMA time-series model was used to approximate each temperature record and a MATLAB program was written to simulate the growth of an individual Chinook salmon from egg to fry. Given a spawning distribution, the model was used to \grow" several hundred ¯sh in each temperature regime for a given period of time, and the distributions of ¯sh weights were recorded in histograms. The distributions of ¯sh weights above and below the dam were signi¯cantly di®erent (p < 0:001) and the temperature regime above the dam produced larger ¯sh than the temperature regime below the dam (p < 0:001). We conclude that the temperature regime below the dam (prior to the construction of the temperature control structure) is less conducive to the survival of Chinook than the temperature regime above. |
