Lac De Sylans
Lac de Sylans is a lake at Le Poizat in the Ain department, France. It is significant for the ruins of one of the 19th century's largest ice harvesting factories and the occasional outflow of water in two directions. Geography The lac de Sylans fills part of the Nantua water gap, which was formed during the last glacial era. The formation of the lake itself is much more recent; it is the result of the collapse of the cliff on the Northern side of the valley a few centuries ago. This huge landslide partially blocked the valley between the ice factory and the source of the Doye, above les Neyrolles, blocking the river that was flowing along what is now the bed of the lake, causing the lake to form. Today the water percolates through the landslide debris to form the source of the Doye. In dry summers the level of the lake can fall by 5m, whereas during wet periods, the level can rise to a point where the water also flows out towards Saint-Germain-de-Joux and Bellegarde-sur-Valse ...

Lake
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
