In order to have high standards of dam safety the prerequisites are designing and constructing dams with reasonable safety margins; operating and maintaining them safely; and having emergency arrangements to address situations that might arise. Operation of dam within its ambit also includes thorough understanding of likely impacts and its management in case of flooding, in any emergency situation or in the event of dam failure, both upstream and downstream on communities living there, their livelihoods and also on infrastructure and property which can get affected. In fact in many countries like Sweden and in many states of the USA, a dam is assigned a dam safety class i.e. A, B or C depending upon the significance of the damage that might occur in case of dam failure, class A being assigned to dams whose failure might cause significance loss of public life and property. Dam safety requirements are calibrated accordingly and a higher burden is put on dam owners of higher class, concerning safety management system, emergency plans, overall assessments, and annual dam safety reporting.

The exploitation of Yamuna Rivers that starts in upper basin comprising Uttarakhand (UKH) and Himachal Pradesh (HP) gets worse as the river is dammed at Hathini Kund Barrage (HKB) while passing through Shivalik Hills located at the border of Haryana and Uttar Pradesh (UP), the barrage has severely compromised lean season (8-9 months) water flow in the river downstream.
As a result, the waterless riverbed resembles a desert till Delhi’s potable water is released back into the river at Palla village, the border of Delhi and Haryana. The absence of flow facilitates intensive illegal riverbed mining for sand and boulders for longer periods in a year which further destroys the river’s eco-system. More over industrial and domestic effluents in great volume from nearby towns reach the river via tributaries, storm water drains. Amid all this successive State Governments show no will to achieve even basic flow of freshwater in the river, even as they keep pushing more dams.
Here is an account of the projects planned and launched in 2016 related to the River Yamuna.
