Some more details on Polavaram Project...
Polavaram -Vijayawada Link
The Proposal: This is the third link proposed to transfer water from
Godavari to Krishna. This link canal takes off from the Right Bank of
Godavari at the proposed Polavaram reservoir and shall divert 5,325
Mcum of water over a length of 174 km. This link will provide total
irrigation benefits of about 5.82 lakh hectares in Andhra Pradesh.
This link will also cater to transfer of 2,265 Mcum of water to the
Krishna Delta, enroute domestic and industrial requirement of 162 Mcum
and 1,236 Mcum of additional water for stabilization of the existing
command under Krishna Delta, besides transmission losses of 260 Mcum of
water. NWDA has completed the feasibility study of the link.
Engineering Aspect: The Polavaram project proposed by the Government of
Andhra Pradesh will be used for diverting the Godavari water through
this link canal which will be received at the existing Prakasam Barrage
on Krishna river at Vijayawada. The FRL/MWL of Polavaram reservoir is
45.72 m and its gross and live storage capacities are 5511 Mcum and
2130 Mcum respectively. The total length of link canal from Polavaram
dam site to its outfall into Prakasam Barrage is about 174 km. The
link canal takes off from Polavaram reservoir with a FSL of 40.232 m
and outfall into Prakasam Barrage at a FSL of 27.965 m. The link canal
is proposed to be operated through out the year. The design discharge
of the canal at the takeoff point works out to be 405.12 cumecs. The
diversion is entirely by gravity.
Environmental Issue: The Polavaram reservoir submerges an area of
63,691 ha comprising of 60,063 ha in Andhra Pradesh, 2,398 ha in
Chattisgarh and 1,230 ha in Orissa. Out of the total submergence area,
the area under cultivation is about 30,650 ha and the forest area 3,705
ha. The reservoir submergence will affect 250 villages and a total
population of about 1.45 lakhs in the States of Andhra Pradesh,
Chattisgarh and Orissa.
