Usually the salmon return during the first three weeks of October with Thanksgiving being the peak weekend.

Jeremy Heighton, the event coordinator with the Adams River Salmon Society, says the salmon were a bit late in arriving, but they are there now.

The 2014 Salute to the Sockeye festival began Friday at Roderick Haig Brown Provincial Park north east of Kamloops.The festival runs until Oct 26.
