Environmental Explosive Threat to Kolleru Lake and Coastal Tracts of West Godavari and Krishna Districts, A. P

摘要

Kolleru is a fresh water lake and debouch of many drains. The coastal tract of west Godavari district is subjected to the progradation of Godavari River delta and intersected by many drains. Geomorphometric and drainage basin analysis is carried out by using Remote Sensing Techniques. Water samples are collected in different seasons and analysed chemically. The proposed cross bund at the straight cut of Upputeru River to create transportation link to W.G.Dt. and Gotlapalem Island hinders the passage of back water into the old course of Upputeru into sea and thereby increase the concentration of salinity which in turn pollute the potable water of the coastal villages. The high tide effect of the backwaters of the sea influence up to Kolleru Lake. Upputeru River and its distribution and consequently the lake and its environs transform into saline from fresh water. The fisherman of the area approached the court of law for the redrvessal of their grievance relating to their livelihood and subsequently the court cleared the way for the cross bund. The whole world is worried about the vanishing of fresh water resources, the short sighted development al plans of the bureaucrats blended with political vendetta hamper and impede the existing fresh water supply to the coastal villages against the hue and cry of local inhabitants, technocrats and environmentalists. Further, this proposed cross bund across the Upputeru near Patapadu to Chinnagollaplem Island convert the fresh water Kolleru Lake and Upputeru River and its distribution into saline. The aquaculture diminishes only the size of Kolleru Lake, but this proposal transforms the nature i.e., fresh water to saline of the Kolleru Lake.
