Watershed Management

Description Several in-lake treatment measures have been taken to remove eutrophication and improve water quality including de-weeding and water hyacinth contral and removal.
Issues Due to deforestation in the catchment area and denudation of vegetation, the rate of soil erosion has increased considerably during recent years and has resulted in siltation of the lake. Severe infestation of the lake by water hyacinth, compounded with the problem of the 'phumids', interferes greatly with water circulation, resulting in increasing rate of siltation and deposit of pollutants in the lake ecosystem.
Other Issues Invasive Species

Biodiversity Conservation

Designations Ramsar Site
Species of Concern Keibul Lamjao National Park, which covers portions of the lake and its watershed, is the only remaining natural habitat for the brow-antlered deer (Cervus eldi eldi).
