The search for April Jones will continue for as long as there is "a realistic prospect of successfully concluding" the operation, according to the police officer in charge.
Superintendent Ian John told the BBC's Clive Duggan that coastguards were searching the estuary every day, and specialist underwater teams were also working in various locations.
He said the volunteer effort was "immense, very humbling... I've never seen anything like this."
