How Telugu Ganga Project Transformed Indian Federalism: Emergency Roots and Regional Rise
As India marks another anniversary of the Emergency, public memory understandably turns to the suspension of civil liberties and the concentration of power. Yet some of its enduring political legacies are hidden in unexpected places. One such legacy flows through the canals of the Telugu Ganga project, a celebrated interstate water-sharing arrangement that offers important lessons about water politics and Indian federalism.
The Telugu Ganga project is often celebrated as a fine example of cooperative federalism. It remains one of the few instances where riparian states—Andhra Pradesh (now bifurcated into Andhra Pradesh and Telangana), Karnataka, and Maharashtra—agreed to share a portion of their Krishna waters to meet the drinking water needs of Chennai in Tamil Nadu, a non-riparian state.
The agreement did not arise from a political vacuum. It emerged from a convergence of opportunistic political interests under the Emergency. In 1976, Prime Minister Indira Gandhi secured the concurrence of the Krishna basin states for diverting water to Chennai. The timing was significant: earlier that year, the DMK government in Tamil Nadu had been dismissed for opposing the Emergency. Securing Krishna waters for Chennai served the Centre's political interests amid growing discontent in Tamil Nadu.
The Congress party was in power at the Centre and in all three riparian states. The Emergency provided the exceptional concentration of power that enabled Indira Gandhi to secure compliance from the states. The idea of bringing Krishna waters to Chennai had existed for over a century, but the Emergency made the agreement possible.
However, the implementation phase after the Emergency proved far more defining for Indian federalism. N T Rama Rao's rise in Andhra Pradesh symbolised the emergence of powerful regional parties challenging central dominance. The Telugu Ganga project could neither be technically feasible nor economically viable without downstream Andhra Pradesh's cooperation, giving NTR considerable leverage.
NTR used the project to build alliances with leaders such as M G Ramachandran in Tamil Nadu, forming a broader coalition known as the “Southern Council” to challenge centralisation. This mobilisation coincided with a wider federal transition marked by the establishment of the Sarkaria Commission in 1983, the first to review Centre-state relations. The Telugu Ganga project became a symbol of southern cooperation and regional assertion, transforming from a tool of central power to a vehicle for challenging central dominance.
Later, Andhra Pradesh's expansion of the project to provide irrigation benefits to drought-prone Rayalaseema generated new disputes with upstream states, who alleged it was an attempt to strengthen future claims over Krishna waters. The saga continues to shape inter-state water disputes and federal negotiations.
