 This point is only 7 km north of Prakasam Barrage but the canal takes another 30 km detour to get connected to the Prakasam barrage pond near Ibrahimpatnam town.The existing Eluru canal from Prakasam barrage was dug across the elevated ridge/doab (where Vijayawada city is located) to cross the Krishna river basin and supply water in to lower Budameru river basin.This canal while crossing the city is a deep cut canal (maximum water level below local ground level).
