Inle Lake, Shan State, Myanmar
Myanmar, Shan State, Nyaungshwe Township
Inle Lake is located in Nyaung Shwe Township, Shan State in Myanmar, and it is the second largest freshwater lake in Myanmar. The Lake covers a total area of 116 km2 and it is one of the highest at an elevation of 880m. During the dry season, the average water depth is about 2.1m, and the deepest point is about 3.7m. During the rainy season, this can increase by 1.5m. The Lake is home to 267 species of birds, over 20 species of snails, 49 species of freshwater fishes including 13 endemic species.
Inle Lake is also unique for the way the local inhabitants have adapted their lifestyle to their environment. Farmers from one of the dominant ethnic groups in the region, the Intha people, practice floating island agriculture, locally called “yechan”. It is recognized as an Association of Southeast Asian Nations (ASEAN) Heritage Park and was declared a UNESCO Biosphere Reserve in June 2015.

The lake, which measures 22km long by 10 km wide, and sits in a valley between the Shan Hills. In villages and towns around the lake, wooden houses are built on stilts becouse of the flood.
The local Intha fishermen steer their one-man boats with a characteristic rowing style, wrapping one leg around their oar. Along with fishing, traditional handicrafts are an important part of the local economy: there are silk weavers and silversmiths plying their trade on the lake.
And as with all of Myanmar, religion plays a massive part in local life, and numerous pagodas and monasteries can be found on the lake and its shores. Around the villages you can see many floating gardens where locals grow vegetables, especially tomatoes.
- Underwater landscape
Inle Lake is very shallow, with an average depth of 2 meters, which can increase by 1,5 m in the rainy season. The bed of the lake is clayey, sandy, which is home to many aquatic plants for example Ceratophyllum demersum, Najas tenuis or Potamogeton lucens.
The floating plants and seaweed form islands on the lake, which provides a hiding place for fish, but the vegetation is so rich that the locals have to thin it out regularly, otherwise their boats will not be able to navigate.
This rich habitat is home to more than 40 fish species, and more than 10 species are endemic like Danio erythromicron, Sawbwa resplendens and Petruichthys brevis.
