Pacific Northwest fishermen have good and very good news this Christmas.
The good news is timely releases of stored water from reservoirs like Lake Roosevelt behind Grand Coulee Dam kept stream levels up and water temperatures down. That helped young salmon migrate to the ocean and adults return home to spawn.
Overall, 2.3 million mature salmon passed through Bonneville Dam, making it the second-strongest year on record for the entire Columbia Basin.
The return numbers were positive upstream as well. According to the East Oregonian, Pendleton, a record number of fall Chinook salmon swam past McNary Dam just south of the TriCities to spawning grounds at Hanford Reach, the Snake River and Yakima Basin. In total, more than 456,000 were counted, breaking the facility’s previous high of 454,991 set in 2013.
Above the reservoirs, however, the record low mountain snow pack — less than 10 percent of normal — and a dry spring and summer took its toll.
Unseasonably low and warmer water all but decimated some endangered Snake River sockeye. The good news is fisheries biologists were able to release 600 hatchery sockeye into Idaho’s Redfish and Pettit lakes to spawn naturally.
