Thotapalli Barrage

Thotapalli Barrage is an irrigation barrage across the Nagavali River near Thotapalli village in Garugubilli Mandal, Parvathipuram Manyam District, Andhra Pradesh, about 15 km from Parvathipuram town. The original barrage was built in 1908 during British rule, and a new barrage was constructed under the Thotapalli Barrage Project to enhance irrigation. It stores water for agriculture and offers views of the river and reservoir.

Visitors can expect a long barrage structure across the wide Nagavali River with sluice gates, a reservoir on the upstream side and canals downstream. The setting is rural and open, surrounded by agricultural fields and low hills. Visitors can walk along the approach road and embankments, view water flow over the gates during high water periods, and observe the reservoir expanse. The area is primarily for sightseeing and photography with no formal visitor complex.

The original Thotapalli Barrage was constructed in 1908 across the Nagavali River during British administration to provide irrigation to Vizianagaram region. The modern Thotapalli Barrage Project was taken up to augment irrigation potential and stabilize ayacut, with the new barrage inaugurated in 2015, enhancing water storage and supply to Parvathipuram Manyam and Vizianagaram districts.

The barrage is significant for its role in supporting agriculture and rural livelihoods in the Nagavali basin. It is an important irrigation source for paddy and other crops in Parvathipuram Manyam and surrounding areas and is regarded locally as a key water resource infrastructure.
