The Cedar River Salmon Journey, a chance to hear volunteer naturalists speak about salmon life cycle, kicks off the weekend of Oct. 6.

Every Saturday and Sunday in October, from 11 a.m. to 4 p.m., the naturalists will staff locations on the Cedar at the Renton Library, the Cedar River Park, Riverview Park, the Cavanaugh Pond Natural Area and the Landsburg Park.

Naturalists will also staff the fish ladder at Chittenden Locks in Seattle, which the salmon, mostly sockeye, use to enter Lake Washington and eventually the Cedar River on their way to spawn.

The Cedar River hosts Chinook, sockeye and coho salmon among other fish species. Cedar River Chinook and Puget Sound Steelhead are currently listed as threatened species.
