Nayak:

To stabilize the existing irrigated ayacut area under Nagarjuna sagar right canal, a new lift project construction with greenfield alignment was started in the first phase of Godavari Penna River linking project by having five step ladder pumping stages and a gravity canals to transfer 7,000 cusecs of Godavari water[65] from Prakasam Barrage back waters into the Nagarjuna sagar right canal near Nekarikallu by utilizing 73 tmcft of Godavari water. With FRL 25M newly created[66] Vykuntapuram Barrage pond will have back waters beyond Pokkunuru up to the toe of Pulichinthala Project. It is more economical to construct first stage pump house of this lift project to lift water from Prakasam Barrage back waters into newly created Vykuntapuram Barrage pond and the second lift stage from Vykuntapuram Barrage pond to existing K.L Rao sagar / Pulichintala Project and later lift stages from K.L Rao Sagar to Nagarjuna sagar right canal.It will shorten the length of this lift project canal, Pressure Main and less number of lift stages and also enables the lifting of water upto Srisailam Project via Existing Reversible Reverse turbine pump houses in Nagarjuna Sagar Dam and Srisailam project. It is even more economical, if we construct a new gravity canal from Ibrahimpatnam to Vykuntapuram Barrage pond to deliver the Polavaram right main canal/ Budameru diversion canal waters directly into the Vykuntapuram barrage pond since canal level is 33 m MSL at Ambapuram hill near Vijayawada. As water supply from Nagarjuna Sagar Left Bank Canal is highly erratic, Muktyala Lift Irrigation scheme is proposed by drawing water from the back waters of Vykuntapuram barrage on left bank of Krishna river.[67]
