The Mullaperiyar Dam: History, Disputes, and Everything You Need to Know
Introduction
The Mullaperiyar Dam, a century-old marvel, stands as a testament to engineering ingenuity. However, beneath its historical significance lies a contentious issue that has ignited disputes between two Indian states: Kerala and Tamil Nadu. The controversy over the dam's safety, water management, and legal battles has not only shaped regional politics but has also become a crucial topic for competitive exams like the UPSC. In this comprehensive guide, we'll delve into the dam's history, the nature of the disputes, the current issues, and what makes it a significant subject for UPSC aspirants.

A Brief History of the Mullaperiyar Dam
Constructed between 1887 and 1895 by the British under the reign of the Maharaja of Travancore, the Mullaperiyar Dam was built across the Periyar River in the Western Ghats. The dam was intended to divert water from the Periyar River basin in Kerala to the arid regions of Tamil Nadu. This engineering feat was achieved by creating a 175-feet tall gravity dam made of lime and surkhi (a mixture of brick powder and sugar).
Key Historical Events:
1886: The lease agreement was signed between the Maharaja of Travancore and the British Government, granting Tamil Nadu rights to the water for 999 years.
1895: The construction of the dam was completed.
1979: Concerns over the dam's safety emerged following a devastating flood, leading to the first major disputes between Kerala and Tamil Nadu.
The Mullaperiyar Dam Dispute: Understanding the Core Issues
The Mullaperiyar Dam dispute is rooted in the agreement signed in 1886, which continues to govern the water-sharing arrangement. However, as time passed, the concerns over the dam's safety and the validity of the colonial-era agreement became points of contention between Kerala and Tamil Nadu.
Safety Concerns and Legal Battles
Kerala argues that the dam, over a century old and situated in a seismically active zone, poses a significant risk to the lives of millions of people living downstream. In contrast, Tamil Nadu insists that the dam is safe, citing expert opinions and wanting to maintain the water levels to meet its irrigation needs.
This disagreement led to a series of legal battles, with the Supreme Court of India playing a crucial role in adjudicating the disputes. Despite numerous judgments, the issue remains unresolved, with both states maintaining their respective positions.
Current Issues Surrounding the Mullaperiyar Dam
The ongoing issues with the Mullaperiyar Dam are multi-faceted, involving safety concerns, water management, and regional politics. Understanding these issues is essential, especially for UPSC aspirants, as they touch upon several aspects of governance, federalism, and environmental conservation.
1. Dam Safety and Structural Integrity
The dam's age and the seismic activity in the region have raised alarms about its structural integrity.
Kerala's demand for a new dam or a reduction in the water level to 136 feet is countered by Tamil Nadu's insistence on maintaining the level at 142 feet.
2. Water Sharing and Interstate Disputes
The dam's water-sharing arrangement has been a significant source of conflict, with Tamil Nadu depending heavily on the water for irrigation and drinking purposes.
The dispute has led to tensions and has occasionally flared up into political issues during elections.
3. Environmental and Ecological Concerns
The surrounding environment, including the Periyar Tiger Reserve, is a critical ecological zone that could be impacted by any changes in the dam's operation or structure.
The Mullaperiyar Dam in the UPSC Context
For UPSC aspirants, the Mullaperiyar Dam is a quintessential case study of interstate water disputes, environmental conservation, and the challenges of federalism in India. The topic is relevant for several General Studies papers and can also be a potential topic for essays.
