Relief on the horizon for dramatically salty Point Reyes water

For decades, salt has infiltrated wells in Point Reyes Station during late summer, but this year the intrusion is higher than ever due to a confluence of factors.

Two bulk users, a construction company and firefighters, consumed more water this year.

Audio: UCLA study: Less snow and more rainfall spell trouble for California

By the 2070s, climate change will reduce snowpack and increase extreme rainfall in the Sierra Nevada and California’s reservoirs will likely be overwhelmed. That’s according to a new study by UCLA climate scientists, who predict that run-off during so-called atmospheric rivers will increase by nearly 50 percent, leading to widespread flooding across the state.
