Even in that primitive era, the Kohali community was recognized as geologists in a broader sense, as geophysics may have been in its infancy in our land.

Archives shows, that the grandiose temples at Jagannath-puri and Bhubneshwar, the picturesque lakes of Kashmir and Rajasthan, were constructed by the Kohali community.

This can be corroborated from documented reports in the Book, " Aaj Bhi Khare Hain Talav " a Gandhi Pratisthan Publication, New Delhi.

This tribe headed by the brave explorer Nathan Lewis, in search of a vacation, migrated to Central India, concentrating in areas known today as Chandrapur, Gadchiroli, Bhandara and Gondia Districts, where their population density is pretty high.

They were awarded large farming tracts as incentives, for constructing tanks, canals and waste weirs for storage and supply of water.

Kolhu and Chimna Patil of the Kohali community, were delegated with the task of constructing a lake (at Navegaon) in the year 1300.

Herds of cattle were pressed into service, to trample the freshy excavated and water-sprinkled soil dumped for the dam-wall, to provide solidity.

After completing the dam, to express their gratitude to God, a fish of the ‘Wadis’ species was caught and adored with 30 Tolas of Gold ornaments and again released in the tank.

For accumulation of water, a 200-yard sloping waste weir was built which also facilitate Eel fish from the back-waters of the sea to enter the lake by rivulets for spawning.

The island in the middle of the lake is known as "Maldonger" and was used by the villagers as a refuge from the marauding 'Pindaris' (A tribe of professional robbers).

One can also join the jungle safari and stroll through the beautiful forest, crossing paths with leopards, sloth bears, gaurs, sambars, chitals and langurs.

Staying in the unique tree-top house, riding a power or sail boat on the lake, are thrilling pastimes.

This sanctuary serves as a living repository of various economical, medicinal, aromatic, ornamental plant species.

All this is coupled with a diversity of terrain having steep ridges, narrow valleys and deep gorges with varying altitude.

Human-wildlife conflict is common, with killing of domestic livestock by tigers and leopards as a frequent phenomenon in the areas neighboring villages.
