To stabilize the existing irrigated area under
Nagarjuna sagar right canal, a new lift project construction was started. The project was to provide five step pumping stages and a canal to transfer 7,000
cusecs of Godavari water from Prakasam barrage back waters into the canal near
Nekarikallu. The first phase was expected to utilize 73
tmcft of Godavari water. Vykuntapuram Barrage backwaters stretch beyond
Pokkunuru to the toe of
Pulichinthala Project. The project's first stage was to build a pump house to lift water from
Prakasam Barrage backwater into Vykuntapuram Barrage pond. The second lift stage moves water from Vykuntapuram Barrage pond to the existing
K.L Rao sagar pulichintala Project. Later lift Stages carry water from
K.L Rao Sagar to
Nagarjuna sagar. A pressure main enables lifting water to
Srisailam Project via the existing
reversible turbine pump houses in
Nagarjuna Sagar dam and its
tail pond project. A gravity canal from Ibrahimpatnam to Vykuntapuram Barrage pond can deliver the
Polavaram right main canal/
Budameru diversion canal waters directly into the Vykuntapuram barrage pond since Polavaram right main canal level is 33 m MSL at Ambapuram hill near
Vijayawada. There is a proposal to link
Nagarjuna Sagar Dam across the Krishna River and
Somasila Dam across Penna River with 400 km canal as part of national river linking program. With help from the Indian Government, AP Govt can construct a new canal up to
Somasila Dam as per DPR of Indian Rivers Inter-link program specifications. Thus the Godavari River water will travel up to Somasila Dam and then Swarnamukhi in Chittoor district via existing Somasila Swarnamukhi link canal.
GoAP can also provide water to
Tamil Nadu with this Godavari water and retained water in Krishna River (15 TMC allocation of Krishna water to Telugu Ganga) will be used for other projects in Rayalaseema region. In the future, a large new dam named Palnadu Sagar across a hill range near
Bollapalle with 700 TMC capacity reservoir is possible using of flood water of Krishna River and Godavari River diverted with this lift project. It will submerge nearly 300Sq KM of land at FRL 260m MSL.Palnadu Sagar spillway with
Francis Turbine will take and release water into Nagarjuna Sagar right canal along with Hydroelectricity power generation. Flood water of Krishna River will be pumped to Palnadu Sagar. The water stored in Palnadu Sagar will be used for irrigation and drinking in drought years. ==References==
