In Upper Columbia River, Salmon Have Spawned for First Time in 80 Years

Good news! For the first time in 80 years, salmon have spawned in the upper Columbia River system in Washington state. In the 1930s and 1950s two dams were built that blocked the salmon from returning to their spawn beds in the river system. Tribal leaders in the area have been working on a plan to return the fish to the are since 2014. This year Colville Tribal biologists were able to count 36 redds (salmon nests) along the river and its tributaries.

This issue is not specific to the upper Columbia River as human made dams have affected the salmon population across the region.

in 2019, 60 salmon were released into the river above the dams. Shortly after, another 100 salmon were released 35 miles into the Sanpoli River and fitted with tracking devices. The scientists were pleased with the results as the salmon decided to stay in the are and appear to be thriving in their “new” environment.
