Happy Wednesday, fellow Cedar River enthusiasts!
Hopefully you’ve been lucky enough to see spawning salmon along the Cedar River. The Cedar River is a vital component in the journey of our local salmonid species, including three of the most threatened species here in Washington, Coho, Chinook, and Sockeye. However, primarily as the result of booming urban growth in the region, our salmon populations are struggling to survive. Local agencies and organizations are trying to determine the best ways to help. Projects that improve and repair healthy salmon habitat are crucial in their recovery.
Salmon rely on shaded, slow moving portions of river to reproduce and mature. Often these areas are found in small channels and ponds connected to the river via its floodplain. In 2012, King County began a project along the Cedar River to do just that – reconnect the Cedar River to its floodplain. Not only will this project provide high quality salmon habitat, but it will help to buffer the impacts of flooding to residents living along the Cedar.
Cavanaugh pond, a previous gravel mine converted into a 14 acre pond in the 1970s, is less than 50 meters from the Cedar River on the left bank. However, a levee currently blocks the connectivity between the Cedar River and Cavanaugh Pond. This project, known as the Riverbend Levee Setback and Floodplain Restoration project, will connect 52 acres of floodplain along about 1 mile of the river just East of Renton in Unincorporated King County. This will be made possible, in part, by removing sections of the levee that currently cut off connectivity with adjacent floodplain, and by raising the bottom of Cavanaugh pond to be the same level as the river. We are excited to watch this project come to fruition, and look forward to seeing improved salmon habitat in this portion of the Cedar River.
