Water levels in Hálslón reservoir, a storage reservoir connected to Kárahnjúkar Hydropower plant, reached their highest point late last Saturday night, Rúv reports. This affects the popular nature spectacle Stuðlagil in East Iceland, one of the largest basalt rock formations in Iceland. Travellers in the area should beware, as glacial water is now flowing out of the Hálslón reservoir, down to its old riverbed in Jökulsá á Dal river. The river flowing through Stuðlagil canyon is stronger than usual at this time of year. Some travellers have gone into the water this summer, putting themselves in risk. Entering the water now is believed to be even more dangerous, as the glacial water can easily grip people with it.
