Several log hazards, including spanning logs and logjams, were identified in 2016 and 2017 on the lower Cedar River from River Mile 13.5 to River Mile 4.5. As a result, this nine-mile stretch between Maple Valley and Renton was closed to all in-water recreational use for several months. In August 2017, King County repositioned many of the logs that were causing dangerous situations, and the King County Sheriff's Office reopened the river. 

Please know all rivers are inherently dangerous, and the lower Cedar River still has hazards. Please see this page for river safety information and this page for boater safety information.
