Authorities confirm that five bodies have been found in the wreckage of a single-engine plane that crashed into a southwestern Colorado reservoir.

Ouray County authorities say a remote-controlled rover and divers spotted the bodies Monday.

Authorities say the wreckage will have to be brought to shore before the bodies can be removed. They say the plane is upside down in about 3 feet of silt and about 60 or 70 feet underwater.

A salvage team is expected to begin raising the wreckage on Wednesday.

Authorities haven't released the identities of the victims.

The Federal Aviation Administration says the plane left Gadsden, Ala., and was on its way to Montrose, Colo., when it crashed Saturday.

The cause of the crash isn't yet known.
