Keibul Lamjao National Park - Hydrologic Features

Hydrologic Features

Hydro–meteorological feature of the area is marked by the dominance of the Indian tropical monsoon with an average annual rainfall of 1,183 mm (46.6 in) with July and August as the wettest months and February and March as the driest.

The size of the Park varies with the seasons as it is formed of phumdis (morass of organic matter). The peripheral areas of the lake are grounded to the bed of the lake during the dry season but get almost substantially submerged for a few days during the monsoon season. It emerges and floats to the surface fully a few days later, separating from the ground; the depth of the phumdi varies from 1 ft (0.3 m) to 4 ft (1.2 m) and during this period the animals in the park move to higher hilly areas. About twenty percent of its thickness floats on the lake, above the surface, which supports the weight of large mammals.

Weather

Temperatures vary from a maximum of 34.4 °C (93.9 °F) in summer to a minimum of 1.7 °C (35.1 °F)in winter. Humidity was a recorded high of 81 per cent in August with a minimum of 49 per cent in March.
