Goetz and Quinn: Behavioral thermoregulation by adult Oncorhynchus tshawytscha prior to spawning 
269 
studies of Chinook and sockeye salmon at the locks; 
J. Newell for providing the sockeye salmon data used in this 
study; and E. Jeanes and C. Morello (R2), K. Kiyohara and 
P. Topping (WDFW), and B. Footen (Muckleshoot Indian 
Tribe) for their assistance with fish capture, tagging, and 
collection of telemetry and water-quality data. We espe¬ 
cially acknowledge C. Ebel, who guided the protection of 
salmon at the locks over his length of service with the U.S. 
Army Corp of Engineers.
