Courtney Buck was with her husband on Sunday when their vehicle plunged 30 metres down an embankment and into the river, south of Clearwater.
Police divers found Skye Buck's body still inside the vehicle two days ago, but Courtney's body couldn't be found.
RCMP Cpl. Dan Moskaluk says the extensive search covered air, land and on the water.
He says the search could resume later if the river conditions and water levels change.
Courtney was a Grade 1 teacher at Raft River Elementary school in Clearwater, while Skye taught math and coached basketball at the municipalities only high school.
