Nagarjuna Sagar tail pond, Hydroelectric reservoir in Nalgonda District, India
Nagarjuna Sagar tail pond is a large reservoir that stretches about 21 kilometers downstream from the main dam along the Krishna River. It holds water that flows down from the primary structure and feeds into the surrounding irrigation systems and power generation operations.
The tail pond began operating in 2008 and was completed in 2014 as part of the larger dam complex. It was designed to work with existing power generation facilities and became part of a regional water management system that had been developing for decades.
This water infrastructure represents Indian engineering capabilities, combining traditional water management principles with modern hydroelectric technology.
Water flow through the reservoir is managed by reversible turbines that generate power and support irrigation across multiple districts. The site sits in a rural area, so facilities are limited and it is best visited as part of a wider exploration of the dam complex.
The tail pond receives water from the Godavari River through an inter-basin transfer system, bringing water from a completely different river system into this reservoir. This connection allows water from one major river to support irrigation in another river's territory.
