Chandigarh:The lake is facing serious issues like weed overgrowth, catchment inadequacy and silting that are significantly shrinking its size and depth. Silting has taken its toll and the volume of the lake has been reduced to 56 per cent of its original.
The lake complex, which attracts hundreds of visitors, tourists, regular morning and evening walkers, fitness freaks and even lovelorn couples, presents a picture of neglect. It has already shrunk by nearly one-third of its original size.
Experts at UT Engineering Department during the study have reached a conclusion that Sukhna Lake dries at a cycle of four years’ time span. According to the sources in the UT Engineering Department, the Sukhna Lake is prone to get dry every four years. Going back to 2004 when Sukhna Lake dried at regulator end and UT Administration carried out desilting, then for four years Sukhna Lake did not dry up.
Similarly, in the year 2009, once again Sukhna Lake dried up and desilting exercise was undertaken at the regulator end. Then in 2013, Sukhna Lake again went dry at regulator end and desilting was undertaken.
“It is the cycle of four year that Sukhna Lake gets dried up and desilting very four years is the only remedy to save Sukhna. The study as per the history, Engineering Department has reached a conclusion that after desilting, for three year the weeds disappear from Sukhna Lake as the roots of weeds are removed with desilting. This also increases the depth of the lake which further is able to hold more water during monsoons otherwise due to higher bed level, the water level touches highest level and flood gates are opened at regulator end,” said a senior officer at UT Engineering Department.
Taking cognisance of the poor condition of Sukhna Lake, Punjab and Haryana High Court has asked UT Administration to submit its reply by September 22 over remedial measure to be taken to save Sukhna Lake. A bench of HC judges along with Amicus Curie will also visit the Sukhna Lake on September 20 to take stock of the situation.
Over the years, the Forest and Wildlife Department had built nearly 200 check dams in the catchment area to prevent the flow of silt into the lake bed.
