of modification of a natural landslide dam for power generation. Attabad Lake in Pakistan was formed by a landslide in 2010. ( high) The Red Lake (Romanian: Lacul Roşu) is a barrier lake in the Eastern Carpathians chain in Harghita County, Romania. The name of "Lacul Roşu" comes from the reddish alluvia deposited in the lake by the Red Creek. The Gros Ventre landslide is an example of a huge, short-lived and devastating landslide dam, ( high). The Lynmouth Flood of 15-16 August 1952 was partly the result of the formation and subsequent failure of a landslide dam on the East Lyn River, sending a wave of water and debris into the town and killing 34 people. Quake Lake, created in Montana in 1959, ( high). The Tangjiashan Lake, a dangerous "quake lake", was created as a result of the 2008 Sichuan earthquake. It was located in the extremely rugged terrain of Tangjiashan Mountain. Chinese engineers, scientists, and soldiers were involved in the digging of a sluice to alleviate the dangers of this one of 34 landslide dams created by the magnitude 8.0 Sichuan earthquake. On June 10, 2008, the lake started to drain via the sluice, flooding the evacuated town of Beichuan. ( high) The Riñihuazo begun on 22 May 1960, after a landslide caused by the Great Chilean earthquake blocked Riñihue Lake's outflow. According to the chronicler Mariño de Lobera a similar event occurred after the 1575 Valdivia earthquake. ( high) The 2014 Oso mudslide dammed the Stillaguamish River in March 2014, creating a lake that blocked Washington State Route 530 and hampered rescue/recovery efforts. Among the most destructive landslide lake outburst floods in recorded history occurred in the Sichuanprovince on 10 June 1786, when the dam on the Dadu River burst, causing a flood that extended downstream and killed 100,000 people. The largest landslide dam in Britain impounds Tal-y-llyn Lake (Llyn Mwyngil) beside Cadair Idris in Snowdonia National Park, Wales. It was first recognised by E Watson in 1962. It is probably over 10,000 years old. Moklishko Ezero in North Macedonia Trebenishko Ezero, near Trebenishta in North Macedonia The 1139 Ganja earthquake triggered a massive landslide on Mount Kapaz, damming the Kürəkçay River, forming Lake Göygöl. The earthquake resulted in as many as 300,000 deaths. References Dams by type Landslide analysis, prevention and mitigation
