World's fastest growing acquatic weed, Water Hyacinth has returned back in the River Sal along the water course between Khareband and Benaulim. Known to multiply within days, weed has spread across the river, especially along the water course from Mungul to Benaulim. A look at the river course from the Khareband bridge would make any stranger to believe that the river has run dry and instead replaced by a green agricultural cover. The last time the weed was removed from the river was around half a decade ago during the de-silting of the river.

Ansupa Lake, one of the two freshwater lakes found in Orissa, is vanishing slowly. Another freshwater lake, i.e. named Saro, in Puri District, has already been wiped out from the wetland maps of Orissa due to anthropogenic pressure. (Correspondence)
