Recent floods in Punjab have raised significant concerns regarding dam management practices. These floods were primarily caused by excessive water discharge from the Bhakra and Pong dams, which were operated amid heavy rainfall in Himachal Pradesh. This situation has brought attention to the timing and regulation of water discharge from dams, highlighting the importance of the Dam Safety Act, 2021, designed to prevent disasters related to dam failures.
The Dam Safety Act focuses on ensuring that dams are operated safely and effectively. It mandates comprehensive surveillance, regular inspections, and proper maintenance of dams. Owners, typically state governments and public sector entities, are required to set up hydro-meteorological networks and inflow forecasting systems. Additionally, they must develop and maintain emergency warning systems to protect downstream flood-prone regions. These entities are also tasked with creating, updating, and implementing emergency action plans for their reservoirs.
Despite existing regulations, several challenges persist in dam management. A significant issue is the absence of regular risk assessment studies and the ineffective execution of action plans. This lack of oversight has led to a decline in control over dam operations, as evidenced by the catastrophic Kerala floods of 2018, where poor reservoir management exacerbated the disaster.
Dams, often regarded as the "temples of modern India" by Jawaharlal Nehru, have immense potential in mitigating downstream flood risks when managed effectively. If operated judiciously, dams can significantly reduce human casualties and economic losses, fulfilling their primary purpose of flood control.
While hydropower projects provide a renewable energy source, they come with environmental challenges that necessitate careful monitoring. There is a critical need to balance energy demands with ecological preservation to achieve sustainable development.
To enhance dam management, it is essential to conduct regular risk assessments and ensure the effective implementation of action plans. Achieving a balance between energy generation and environmental safeguarding is vital. Collaborative efforts among dam owners, governmental bodies, and experts are crucial for the safe and sustainable operation of dams.
