The reservoir created by the Rengali Dam is known as Rengali Lake, which serves as a significant site for migratory birds during winter.
The dam was commissioned in 1985 after a project timeline that spanned nearly a decade.
The power house operates using water released from the reservoir through a dedicated intake structure.
The total gross storage capacity of the reservoir is approximately 4,393 million cubic meters.
The dam is part of a two-stage development plan that includes a smaller barrage downstream at Samal.
Rengali Dam is a masonry gravity dam constructed across the Brahmani River in the Angul district of Odisha. It serves as a multipurpose project providing both hydroelectric power generation and irrigation for the region. The reservoir created by the dam is the second-largest in Odisha, covering a catchment area of approximately 25,250 square kilometers. The project includes a dam spanning 1,040 meters in length and 70.5 meters in height. It features a power station with an installed capacity of 250 megawatts, utilizing five turbine units. The surrounding area includes Rengali Project Town, which was developed to house project staff and facilities. The dam plays a critical role in flood moderation for the downstream Brahmani delta.
The viewpoint located on the bridge overlooking the spillway gates.
Carry valid government-issued identification, as entry to the dam vicinity may require security clearance.
Visit during the monsoon's end to witness the spillway gates in operation when water levels are high.
Bring binoculars if visiting during winter months to observe migratory bird populations on the reservoir.
Do not attempt to swim in the reservoir or the river downstream, as water levels fluctuate rapidly due to power plant operations.
Access may be restricted during periods of high rainfall or emergency flood discharge protocols.
Maintain silence near the dam structure and follow all marked restricted access zones for safety reasons.
