Groundwater levels have taken a dip in the past one month in Krishna District despite rain due to three cyclones – Helen, Phailin and Lehar – brought along with them while crossing the Andhra Pradesh coast in October-November.
The groundwater levels, which were recorded after the three cyclones, present a dismaying picture to farmers and others who desperately rely on it. Helen and Phailin brought continuous downpour across the district, but the impact of the rainfall on the groundwater table is meagre, and nothing on the district average by November 30.
Krishna District average groundwater level was at a depth of 5.04 meters from the surface of the earth before the cyclones (by October 30). Post cyclones (by November 30), it fell to 5.15 meters. “There was zero increase of the water table in a few parts and it even fell further down in majority of the areas in the district.
“Prime reason was that the rainwater just ran off before the sand particles under the earth absorbed it,” Groundwater Department Assistant Hydrologist U. Rajasekhar told The Hindu . Geographically speaking, the groundwater table saw a negative impact, gaining nothing from the recent changes in weather.
“The current average availability of groundwater from the surface of the earth in upland areas is 6.64 meters, which was quite better with 6.33 meters a month ago,” explains Krishna District Groundwater Deputy Director A. Varaprasada Rao. The officials could come out with their conclusion on whether the groundwater table would help avoid woes of potable water in summer or not based on the December groundwater table.
