Temperature differences and slow-moving water at the confluence of the Clearwater and Snake rivers in Idaho might delay the migration of threatened fall Chinook salmon salmon and allow them to grow larger before reaching the Pacific Ocean. To find out if that's the case, a team of researchers is implanting young fish with acoustic and radio tags to track their movement and using hydrological sensors to measure water temperature and speed.
