Kern River Has a Deadly History
Despite signs intended to warn swimmers about the river’s cold, fast-moving water, people continue to tempt fate.
The signs, including this famous one, are periodically updated with the river’s death toll since 1968. It’s up to nearly 300.
Fifteen people died in 2017 alone. That was, like 2019, a heavy rainfall and snowpack year. Nine people drowned in the river in 2011, another year of powerful runoff from the Southern Sierra.
