The International Commission on Irrigation and Drainage (ICID) has officially included Sir Arthur Cotton Barrage across the River Godavari at Dowlaiswaram near Rajahmundry in its “Register of World Heritage Irrigation Structures.”

Constructed in 1852 by British engineer Sir Arthur Cotton, this historically significant weir-barrage originally aimed to redirect the floods of the Godavari into irrigation canals — transforming how water was used in the delta. Before its construction, most farmland depended on rainfall, while the river’s floodwaters flowed unused into the Bay of Bengal.

With this recognition, the Cotton Barrage becomes the fourth irrigation structure from the Indian state of Andhra Pradesh to receive the ICID’s heritage tag.
The tag was formally awarded during the 24th ICID Congress in October,2022 in Adelaide,Australia. The recognition underlines not just antiquity, but also continuous relevance: the barrage remains functional, supporting agriculture and water needs in a major river delta after nearly 170 years since its first version.
The heritage status underlines not only the structure’s antiquity but also its continued relevance — the barrage still supplies irrigation water to more than 10 lakh (one million) acres in the twin Godavari districts.
Besides Cotton Barrage, the other irrigation-heritage projects from Andhra Pradesh recognized earlier are: the KC Canal (in Kurnool), the Cumbum Tank (in Prakasam district), and the Porumamilla Tank (in Kadapa district).
More recently (after Cotton Barrage), the Prakasam Barrage (Old Krishna Anicut) was also awarded as a heritage irrigation structure by ICID in 2023, making it among the 19 sites globally recognized that year.
Heritage recognition by ICID is significant: It highlights how these historic irrigation structures are not only engineering landmarks, but also living infrastructures that continue to serve agricultural communities across decades — reinforcing water security, supporting livelihoods, and preserving a legacy of water-management engineering from colonial and pre-independence India.
Present condition:
Responding to the concern over many among 175 rusted gates in the old structure and the non-functional status,causing water loss and poor flood control, the state government of Andhra Pradesh had sanctioned ₹ 150 crore (in 2025) for a major restoration — including replacement of damaged gates, installation of new sluice gates, scour sluices for silt removal, and other civil/electrical works.
