Overview
The Vamsadhara flows from Odisha into Andhra Pradesh as an east-flowing river to the Bay of Bengal. Its waters were the subject of an inter-state tribunal, set up in 2010.
It rises near Kalahandi in the Eastern Ghats of Odisha and enters the sea near Kalingapatnam in Srikakulam district.
The tribunal gave its final award in 2017 and allowed Andhra Pradesh to build a side weir at Katragadda subject to conditions.
The Neradi barrage proposal is the main point of contention between the two states.
