Jhanjavati Project 18°51′49″N 83°26′05″E is located at Rajyalaxmipuram village in Komarada mandal of Vizianagaram district on Jhanjavati, a tributary of River Nagavali.
It is a rubber dam and first of its kind in Andhra Pradesh and India and the biggest in Asia.
It is aimed to utilize 4 TMC of available water and to irrigate / stabilize a total ayacut of 24,640 acres (9,970 ha) in Vizianagaram District.
It was dedicated to the nation on 1 January 2006 by Chief Minister Y. S. Rajasekhara Reddy.
The rubber dam was installed on a concrete plate in technical collaboration with Hydro-Construct of Austria.
However, the prior agreement between Odisha and Andhra Pradesh on this project permits to raise the maximum reservoir level submerging Odisha area up to 480 feet (150 m) msl.
This dispute is unsettled till now preventing use of the project's full irrigation potential for last 20 years due to present 0.6 tmcft reservoir storage capacity against 4 tmcft planned storage.
Andhra Pradesh wants to resolve the issue by constituting Nagavali water dispute tribunal under the Interstate River Water Disputes Act as the dispute is not getting settled by negotiations between the two states.

Thotapalli Barrage is located on Nagavali River at village Thotapalli in Vizianagaram district and presently being upgraded as barrage.
