The reservoir which held some hope in the disappearance of Madeleine McCann appears to have not revealed anything to detectives who scoured it.
The Barragem do Arde reservoir in Portugal, was cordoned off in May, about 48km from where three-year-old McCann went missing 16 years ago.
The Independent reports the prime suspect in McCann's disappearance, convicted sex offender Christian Brueckner, visited the reservoir's peninsula regularly and has previously described it as a "little slice of paradise".
But in a new report from The Sun, detectives searching the reservoir have conceded there is "no compelling evidence" that McCann is there.
It's reported that holes, up to two feet deep, were dug up in the reservoir in hopes of uncovering clothing fibres.
German public prosecutor Han Christian Wolters told the newspaper Bild: "Please don't expect too much".
The large operation at the reservoir saw German police use sniffer dogs, radar equipment and search teams.
It came after police reportedly received a tip-off that Brueckner had visited the area not long after McCann went missing in May 2007.
McCann disappeared from her bed at the family's holiday apartment in a Praia da Luz resort while her parents were out eating 50 metres away.
It's been 16 years since the young girl's disappearance and the revelation the reservoir had nothing, is likely to be another blow to McCann's family and supporters.
