Just before 9:30 a.m. Sunday, US Coast Guard Station Umpqua River was notified of capsized boat just outside the Umpqua River Bar.
According to US Coast Guard 13th District Public Affairs, there were 5 people in the water.
Three were recovered, but 2 were stuck in the boat's cabin - a 5-year-old girl and middle aged woman.
The Coast Guard responded with a 29-foot response boat, a 47-foot life boat and a helicopter from North Bend.
They deployed a rescue swimmer from the helicopter who was able to get both the girl and woman out of the cabin, but both were unresponsive.
Despite CPR efforts, the woman was pronounced deceased at the dock. The child was transported to the hospital, where she later died, the Coast Guard said.
A small boat was able to bring the survivors in the water to safety.
The operation took about 40 minutes.
The capsized boat was a recreational, 22-foot pleasure craft. Coast Guard officials said they were working to recover it.
Some Coast Guard crew members were distraught about the situation and aren’t working Monday, officials said.
The identities of those involved have not been released.
