Graenalón Glacial Lagoon Flooding

Glacial lagoon Graenalón, which lies below the southern border of Vatnajökull glacier in southeast Iceland, began flooding on Tuesday. The lagoon floods every few years but the floods are not dangerous because they occur far from human habitation.

Water from Graenalón currently floods Súla river, which has been reddish brown in color since the flood began. Súla then runs into Núpsá river by Núpsvötn lakes, Morgunbladid reports.

Scientists monitor the water level in Graenalón and can thus calculate when the lagoon will flood. Last week the water level had become as high as when the lagoon flooded last in 2005. This year’s flood will be over soon.
