HISTORY:
Berijam Lake is a reservoir near Kodaikanal town in Dindigul district of Tamil Nadu, South India. It is at the old site of “Fort Hamilton”, in the upper Palani hills. The lake, created by a dam with sluice outlets, is part of a micro–watershed development project. Periyakulam town, 18.7 kilometres (11.6 mi) to the SE, gets its public drinking water from the lake. The lake’s water quality is excellent.
There was originally a swamp here known as the Berijam swamp.The previous existence here of a large lake, evidence of which was visible nearby, was first recorded in 1864 by Colonel Douglas Hamilton of the 21st Regiment of the Madras Native Infantry. No written record or even local legend regarding the existence of this ancient lake survives. However, judging from visible traces of its shoreline which still remained in 1906, it must have been nearly 5 mi (8.0 km) long, up to 3,960 ft (1,210 m) wide and up to 70 ft (21 m) deep. It was apparently formed by the side of a hill slipping down into a valley which slopes northwards, and damming up the stream which ran to the Amaravati River at the bottom of it. This stream apparently eventually cut its way through the huge natural embankment so formed, and thus emptied the lake this landslide/dam had once created. The dam was about 600 ft (180 m) long and the breach in it was about 300 ft (91 m) across and 90 ft (27 m) deep.
In 1864, Colonel Hamilton submitted a report stating that the Berijam Lake area was the best site in the Palani Hills for a military cantonment or Sanatorium. A military outpost later built here, Fort Hamilton, was named for him. There was in fact no ‘fort’ at the place, only a small hut.
Berijam lake was artificially created in 1867, when Sir Vere Levigne, Collector of Madurai, donated part of his personal retirement funds for building the dam. Subsequently, the dam and reservoir were enlarged and a pipeline was built to supply drinking water to the Periyakulam Municipality. The scheme was completed in 1912 at a cost equivalent to US $138,500.
Berijam has a 100-year-old 2-story brick building, partly damaged and blackened over the years, with a bright yellow painted name reading “Britisher’s Transit Camp”. This is one of several transit camps built every 15 km (9 mi) for the soldiers to rest along the 230 km (143 mi) British “Escape Route” from Kodaikanal via Top Station and Munnar to Kochi, built during World War II. While most of the transit camps are now either dilapidated or demolished, the one at Berijam still stands.
Berijam Lake has been studied palynologically revealing a 20,000 years story by pollen particles deposited in lake sediments. The time span between 20,000-17,000 years before present (B.P.) experienced cold and dry climatic conditions. After this period arid oxidizing environmental conditions prevailed for a period of 2500 years. The time span between 14,500–7;000 years B.P. witnessed a climatic amelioration phase leading to a warm and humid climate. From about 7,000 years B.P. to present the area has had a cool and humid climate.
