Cedar River Professional Review and Guide
"The Cedar River flows under the Renton Library and can be seen from the I-405 S curves. A raging Cascade river in its youth, its final few miles offer an active paddling experience through a bucolic semirural area.
The river is small and intimate, a rocky run with brushy bends, an occasional high bluff, lots of gravel bars, numerous species of birds (including mallards and mergansers), and evidence of beavers and muskrats. Its run through downtown Renton is unique, with anadromous fish visible in the clear cool water, even under the library. The Cedar—along with the Missouri, the Yellowstone, the Lower Snake, and several other rivers—made American Rivers’ list of the 10 Most Endangered Rivers in 1999 due to urban sprawl and water withdrawals. (American Rivers is North America’s leading river conservation organization.)"
