Fishermen have built entire settlements on them, called phumshangs, and the residents harvest fish through holes cut in the vegetative mat beneath their floors. In the Meitei language, "Lok" means stream and "tak" means the end. Loktak is where the streams gather and stop. It is the largest freshwater lake in northeast India, and it breathes -- swelling from 250 square kilometers in the dry season to 500 during monsoon rains.

By fixing the water level for power generation, the Ithai Barrage disrupted Loktak's natural pulsation -- the seasonal rise and fall that flushed sediment, renewed nutrients, and allowed phumdis to settle and reg...
