Chilika Lake

[4][5][6] It is spread over the Puri, Khordha and Ganjam districts of Odisha state on the east coast of India, at the mouth of the Daya River, flowing into the Bay of Bengal.

Geological evidence indicates that Chilika Lake was part of the Bay of Bengal during the later stages of the Pleistocene period (1.8 million to 10,000 years BP).

Excavations were conducted by the Archaeological Survey of India at Golabai Sasan (20°1′7″N 85°32′54″E / 20.01861°N 85.54833°E / 20.01861; 85.54833) north of Chilika lake in Khurdha district.

This also indicates that Chilika lake was close to Golabai and it facilitated the maritime trade of people in the area during the ancient period.

[9] Ancient texts say the southern sector of Chilika was a major harbour for maritime commerce, when Kharavela (c. 209 BCE–after 170 BCE), the King of Kalinga, was known as the "Lord of the Sea".

[10] Ptolemy (150 CE), the Greek geographer, referred to Palur as the port Paloura, located close to the point of departure situated outside of the southern tip of the lake at Kantiagarh, from where ships bound for different parts of Southeast Asia sailed.

After 639, the Chinese pilgrims Fa-Hien and Hiuen-Tsang mention a famous port "Che-li-ta-loChing" near the shore of the ocean which was a thoroughfare and resting place for seagoing traders and strangers from distant lands.

[9] A fourth-century legend, often told to explain the birth of Chilika, states that the pirate king, Raktabahu, planned to attack Puri with a huge fleet of ships.

[2] Archeological excavations discovered seventh-century ship anchors and stone memoirs dedicated to battle heroes at a village named Kanas, about 25 km (16 mi) north of Chilika on the banks of Nuna river, which flows into the lake.

A 10th-century text, the Brahmanda Purana, mentions Chilika Lake as an important centre of trade and commerce, and a shelter for ships sailing to Java, Malaya, Singhala, China and other countries.

Fateh Muhammed, in turn, was rewarded by the British with freehold of the areas of Malud and Parikud, of the present day Garh Krishnaprasad revenue block.

Over the years, poets including Kabibar Radhanath Ray and Pandit Godavarish Mishra, freedom fighters and Saints have extolled historicity of the lake as pertinent to its cultural, spiritual, religious and scenic aspects.

[10][11]"Gopabandhu Das, a famous Odiya poet, became impatient to see the beauty of the march of colorful sights and sounds of Chilika lagoon while going by train.

Geological studies indicate that the coastline extended along the western shores of the lake in the Pleistocene era with its northeastern region lying under the sea.

That the coastline has moved eastward over the ages is supported by the fact that the nearby Konark Sun Temple, built originally on the seashore a few hundred years ago, is now about 3 km (2 mi), away from the coast.

With the rise in the sea level, the sand beach grew gradually, progressed seaward to the northeast and formed the spit of Chilika.

The lake experiences South–west and North-east monsoons during June to September and November to December respectively with an average annual rainfall of 1,238.8 mm (48.77 in), with 72 rainy days.

[20] Adverse tidal exchange occurred due to the littoral drift along the coast line causing flow reduction and shifting of the lake mouth every year.

In summary, siltation from upstream led to shrinkage of the water surface area, decrease of salinity and growth of invasive freshwater aquatic weed infestation, all of which had a negative impact on the habitat of wildlife and fishery resources.

The CDA was set up for restoration and overall development of the lake under the Indian Societies Registration Act as a parastatal body under the administrative jurisdiction of the Forest and Environment Department, with the following charter: The governing body of the Authority is headed by the Chief Minister of Odisha State and has people's representatives (Members of Parliament and Legislative Assembly), representatives of the fisherfolk communities and secretaries of the key departments, experts and eminent scientists as its members.

Hydrobiological monitoring was supported under the Odisha Water Resources Consolidation Project of the World Bank, to the extent of Rs 10 million (US$220,000).

[20] The ameliorative actions were taken by the CDA to restore the ecosystem and to improve the socio-economic conditions of the communities living around the lake and on its islands involved the following.

The effective ameliorative action was the hydrological intervention of opening the new lake mouth and channel to the sea through the barrier beach at Satapura.

In September 2000, the desiltation of the channel connecting the lake to the sea and opening of a new mouth to restore the natural flows of water and salinity levels was carried out.

Migratory water fowl arrive here from as far as the Caspian Sea, Baikal Lake and remote parts of Russia, Mongolia, Lakah, Siberia, Iran, Iraq, Afghanistan and from the Himalayas.

Removal of invasive species of freshwater aquatic plants, especially water hyacinth, due to restoration of salinity, is a contributing factor for the recent increasing attraction of birds to the lake.

[10] With the abolition of zamindari (land lordship) system in 1953, traditional fishing areas continued to be leased out to cooperatives of local fishermen.

The High Court of Odisha ordered the Government to enact changes that would protect the interests of traditional fishermen and since then no new leases have been reported.

[20] Within the lake precincts, Odisha Tourism Development Corporation Ltd. (OTDC) and the Revenue Department of the state government offer boat cruises.

The film provides account of how uncontrolled human intervention has turned the lake, which was a sustainable livelihood resource, into a mere waterbody that tourists can dip their feet into.
