Fall chinook returning to the Snake River have set a new record for the third year in a row.
Data released by the Nez Perce Tribe show a new record of 9,345 redds, or gravel nests, were built by returning adults in the Snake River Basin between Lower Granite and Hells Canyon dams.
The previous record was set in 2014, when 6,714 redds were counted, according to the Columbia River Inter-Tribal Fish Commission. The new record coincides with the third highest adult Snake River fall chinook return, 59,300, since the four lower Snake River dams were completed in 1975.
