Icelandic Lakes and Reservoirs

Iceland's diverse water bodies range from the massive Þórisvatn reservoir to the tectonic rift lake Þingvallavatn, situated on the Mid-Atlantic Ridge. This collection features volcanic crater lakes like the geothermal Víti, the bird-rich eutrophic waters of Mývatn, and man-made reservoirs such as Blöndulón. These sites showcase unique geological phenomena, including glacial runoff, geothermal activity at the Blue Lagoon, and coastal rock pools like Brimketill, providing insight into the island's volcanic and hydraulic landscape.
