Madeleine McCann - Portugal reservoir - 2023-2006 - Shrine Spot 2007

I made a special video using Google Earth to show how the reservoir has changed over the years.
At this place marked, a memorial was found for Madeleine McCann in December 2007, half a year after her disappearance. The area is now under water again.
Is it possible there's something here that might help with her disappearance? Do you have info? Contact the police of your country.
