Rara Lake (Nepali: राराताल raratal) is the biggest natural lake of Nepal. It is in Rara Village Development Committee, Mugu District, Karnali Zone in the Mid-Western region.

The lake has a slightly oval shape and is entirely in the Rara National Park, about 300 km (190 mi) north-west of the capital, Kathmandu.

Features[change | change source]

Lake Rara is at an altitude of 2,990 metres (9,810 ft) above sea level covering an area of 9.8 km2 (3.8 sq mi).[2] The lake has a length of 5.1 kilometres (3.2 mi) and a width of 2.7 kilometres (1.7 mi) with a maximum depth of 167 metres (548 ft). It flows into the Karnali river via the Nijar river (Nijar Khola).[3]

The lake was classified as oligotrophic (an environment that offers little to sustain life) in limnological terms, meaning that is very slightly polluted.[2]

Climate[change | change source]

The climate of the Rara National Park, where the Lake Rara is, is a temperate climate with temperatures between 27 °C (81 °F) in summer and −4 °C (25 °F) in winter.[4]

Animal life[change | change source]

In the Lake Rara there are three endemic fish species (Schizothorax macrophthalmus, S. nepalensis and S. raraensis),[5] and one endemic frog (Paa rarica).[6]

Many waterfowl spend the winter months in Lake Rara; some of them are gadwall, mallard, northern shoveler, Eurasian teal, tufted duck, common goldeneye, goosander, Eurasian coot and solitary snipe.[2]
