The first mesmerising sight that captivated me with its vivid blues and greens was the water body called Dipor Beel. It was October. Migratory birds had not arrived yet. The calm blue of the freshwater lake looked brilliant even as it blended with the bright blue autumn sky laden with dense pristine clouds.
Surrounded by shades of wise old trees bowing with their abundant green leaves and full branches almost touching the serene water! A solitary boat lay amidst the wilderness of weeds. We stopped by the lake awhile. Just resting in solitude or reading a book under the shade of a tree, could make one's day right there.
Dipor Beel, 13 km south-west in the direction of Guwahati, on the bank of the Brahmaputra, is bounded by highlands. Precisely on NH 31 on the Jalukbadi-Khanapada bypass.
As one reads under a tree shade, or walks a bit along the grasses, one could often be greeted by a water fowl walking in careful gait.
The beautiful freshwater lake gets is showered with rainwater as it also gets water from Basistha and Kalmani rivers. Heard one needs to visit Dipor Beel in winter when it is home to 19,000 kinds of birds in just a day! Among them, some globally threatened species of birds. Birdlife International has marked it among the best bird- sighting areas of the country.
We were attracted by the variety of aqua vegetation along the lakeside. There were orchids, medicinal plants, all in effortless wilderness. When we visited, it was afternoon. Aquatic grasses, water hyacinth, water lilies rested in silent whispers as submerged vegetation. The marshy lands, the emerged vegetation , an egret at a distance perched atop a bare tree stump. It was all wild. All silent. All soul- healing yet mind-enhancing.
This wetland with Burma Monsoon Forest vegetation, has the beautiful name 'Dipor Beel' is inspired from the sanskrit word dipa which means elephant and beel in Assamese indicating a large water body, inhabited by elephants. As we sat in silent contemplation at the still blue waters, I remember, had read somewhere that Dipor Beel was an important dockyard of the Tai-Ahom as well as the Mughals, taking us to medieval history of the conflict between Tai-Ahom and the Mughals.
Dipor Beel, a blue green healing yet rejuvenating balm to the mind and soul, is a welcome entry to the wonders of the north-east. Undeniably an unmissable stop on the way from Guwahati. Not having spent an hour soaking in its beauty, much more so in winter would be missing out on an apparently small yet abundantly beautiful resting spot.
