With water levels in Sukhna Lake reaching their lowest ever,a study has been initiated to measure and monitor water levels in the lakes catchment area. A detailed study of the all water bodies in the Sukhnas catchment area had earlier been carried out to determine the lakes storage capacity.
Now,members from the Society for Protection and Conservation of Environment (SPACE) will measure levels in all water bodies in the lakes catchment area. The exercise will continue till June next year and the water levels would be monitored at regular intervals.
Sukhnas catchment area has around 150 water bodies and when these overflow,water enters the lake. When the lake had dried up during summers,water was released from the water bodies in an attempt to increase the levels.
Chairman of SPACE Dr S S Grewal said that at present water is flowing into the lake from Nepal and a little from Kansal. The rainfall this year has been less. Due to this,the amount of water entering the lake has been less. The level is still shallow. In the catchment area,the causeways have unintentionally blocked the flow of water. There is a need for this water to flow freely into the lake. Better rainfall in September could improve the situation, he added. The rainfall,however,has been localised. Even in Chandigarh,at a given time some sectors received rain while the others did not.
Dr Grewal had earlier got pits dug up in the trough area to see whether these would fill up. This was done to ascertain the amount of water present in the catchment area. With the pits having filled up,Dr Grewal says that this proves an earlier study that the catchment area has sufficient water. The catchment area has a large number of silt retention dams that were constructed to prevent silt from entering the lake. The silt was affecting the storage capacity of the lake. Along with the silt water is also retained in the catchment area.
