Devistating report indicated only 10 percent of Snake River Sockeye survived in 2015

This year’s hot summer and low river flows devastated Snake River sockeye.

“We had August-like temperatures in late June, square on the shoulders of the sockeye migration,” said Ritchie Graves, with NOAA Fisheries.

It turns out 90 percent of Snake River sockeye were dead before they reached Ice Harbor Dam, the first of four dams on the lower Snake River.
