An underwater recovery team has pulled Skye and Courtney Buck's car from the water.
It was submerged in about 3½ metres of water about six metres from shore, said RCMP Const. Lesley Smith.
They also retrieved Skye Buck's body, but continue to look for his wife, who is presumed dead.
"We are making every effort possible in locating Courtney Buck. That river is fast flowing at this time and of course the North Thompson will run into the Thompson River ... into Kamloops," said Smith.
"At this time we are just focusing on the areas that we can get to."
Smith said an RCMP helicopter will search the river from the air if weather conditions improve, and searchers are also combing the sides of the North Thompson River.
The Bucks were high school sweethearts and popular teachers in Clearwater.
Grief counsellors are in the town helping people deal with the tragedy.
