LAKE TAHOE (AP) — A woman drowned after falling off a boat carrying six children on Lake Tahoe and a man who jumped off the boat to try to rescue her had to be hospitalized for severe hypothermia, authorities in northern Nevada said Saturday.

The Tahoe Douglas Fire Protection District said the incident occurred Friday evening near Zephyr Cove, which is on the east side of the lake that straddles the California-Nevada border.

After the woman and the man went into the water, the boat with the children still aboard drifted into the middle of the lake where a fire district boat crew rescued the children, who were unhurt, the district said in a statement.

Rescue personnel were unable to revive the woman.

The Sacramento Bee reported that the Nevada agency’s personnel responded to the scene after receiving a 911 call believed to be made by someone who heard the children yelling for help, Tahoe Douglas Fire Protection District Fire Marshal Eric Guevin said.

Several miles away, crews had rescued the man, who had been in the water for over an hour, and transported him to Barton Hospital for severe hypothermia, the Bee reported. He was listed Friday night in critical condition, officials said.

Guevin told the Bee that the woman was the mother of some of the children, part of a blended family but authorities did not immediately know the relationships between the people involved and ages of the children.
