The original dam was constructed between 1836 and 1838 by British irrigation engineer Sir Arthur Cotton.
Mukkombu translates to 'three branches,' referring to the way the river splits at this location.
The project was engineered to protect the older Grand Anicut from excessive silt accumulation.
The structure acts as a vital regulator for the agriculture of the Cauvery Delta, known as the 'Rice Bowl of Tamil Nadu'.
The barrage spans the width of both the Kaveri and Kollidam rivers.
The site includes a long bridge that connects the Tiruchirappalli and Srirangam regions to the surrounding rural areas.
Mukkombu Dam, also known as Upper Anaicut, is a historic water control structure built across the Kaveri River near Tiruchirappalli. The dam serves as the point where the Kaveri River splits into the Kaveri and the Kollidam distributaries. The site consists of a 685-meter long barrage designed to regulate water flow for irrigation in the Thanjavur delta region. Sir Arthur Cotton modeled the current dam’s design after the ancient Grand Anicut, located further downstream. A new barrage was constructed alongside the historic dam in recent years to enhance structural stability and water management capabilities. The site features a scenic garden area and a children’s play park located along the riverbanks. Visitors can walk along the dam top to observe the river bifurcation. The location remains a popular destination for locals during the monsoon season when water levels rise significantly.

Visit during the evening to see the structure illuminated against the water.
Carry sun protection as the dam walkway offers minimal shade.
Stay behind designated safety barriers as water currents near the sluice gates can be unpredictable.
Do not attempt to climb down the embankments to the water level, as the terrain is slippery and currents are strong.
Maintain respectful behavior near water structures; littering is strictly prohibited in the park areas.
