River Safety Notice
River conditions can change abruptly due to upstream reservoir releases, sudden mountain thunderstorms, flash flooding, and seasonal snowmelt surges. Always scout rapids prior to commitment, wear an approved USCG Type III/V Personal Flotation Device (PFD), carry appropriate rescue gear, and check local emergency management bulletins before launching.
