Yosemite water danger
Yosemite Search & Rescue warns rivers and waterfalls are running high and fast as snowmelt accelerates — and to stay well back from water’s edge. (unofficialnetworks.com) Park stats show 15–20 water‑based rescues each year, most triggered by people getting too close to swift currents — treat the banks as hazardous this spring.

Park staff logged runneling and other signs of early melt beginning the week of March 8–9, 2026, and wrote that spring runoff “has begun, about a full month or so earlier than most years.” (nps.gov) Snow‑water‑equivalent on March 1 measured about 65% in the Tuolumne River basin and 71% in the Merced River basin, and the park’s conditions page lists Yosemite Falls, Vernal Fall, Nevada Fall and Bridalveil Fall as flowing high. (nps.gov) Yosemite National Park Public Affairs Officer Scott Gediman told Fox Weather the Merced River was likely to remain above flood stage for several days following months of heavy snowpack. (foxweather.com) The park’s water‑safety guidance says 15–20 visitor rescues each year are directly tied to people ending up in mountain water—either intentionally or accidentally—and that water‑related accidents are the park’s second most common cause of death. (nps.gov) Friends of YOSAR and news reports show 191 search‑and‑rescue responses in 2024 (90 classified as “major” and 39 requiring aviation), and supporters reported calls rising to a near‑20‑year high in 2025 with about 247 incidents that season. (sfgate.com) (newsbreak.com) The park and partners have expanded preventive search‑and‑rescue outreach this year—continuing the PSAR program’s trailside info stations, seasonal rangers, and engineering measures such as railings and closures to reduce avoidable water incidents in 2026. (yosemite.org) Observers noted an abrupt warm spell in mid‑March with forecast highs into the 80s and about 18 inches of snow having buried Yosemite Valley less than a month earlier, conditions the UPI report said would fuel rapid snowmelt and boost waterfall and river flows.
