In Guildford, police are searching for a man who eyewitnesses said was overcome by strong currents while kayaking on the River Wey.
It is thought he was kayaking with his son and dog before they capsized. The boy was rescued, but his father was washed away.
Ch Insp Dave Mason, of Surrey Police, said: "We have a large number of officers out looking for this man alongside a number of fire crews.
"The man was spotted in the water by several members of the public and was clearly in difficulty due to the extremely strong current.
"We are doing everything we can to try and find him."

Passengers told of their terror as planes coming in to land at Gatwick and Heathrow airports were forced to divert to Birmingham and Manchester.
Dan Prance, 27, from south London, branded his trip back from Budapest the "worst flight of my life" and said passengers were so relieved when they finally touched down that many burst into tears.
He said: "When we approached into Gatwick from Budapest the plane was dropping suddenly and swinging left to right. You could see from the windows there was a massive storm happening outside, the wind and rain was smashing against the glass.
"We got closer to the ground at Gatwick until the captain suddenly aborted the landing and we went shooting back up into the sky to attempt again.
"The captain came on the PA system and explained that the winds were way too strong for this kind of plane to land and he had to abort the landing at the last moment for safety. It was absolutely terrifying."
He said they were eventually diverted to Birmingham but only discovered where they were when they landed and people checked Google Maps.

"Our 999 control officers have worked tirelessly to deal with hundreds of calls and get fire crews there as quickly as possible.
