- Sriramsagar, Floodflow canal, Kakatiya canal, Godavari north canal
- Krishna
- Bhima, Tungabhadra
- Srirsailam project, Nagarjunasagar project, Prakasam barrage

|
- Godavari
- 1480 TMC alloted
- 70% of total flows wasted in to the sea
- Copious flows available only 3 months, July-September
- 80% of AP catchment area is in Telangana
- Major projects – Sriramsagar
|
|
4
|
- Krishna
- 800 TMC alloted, drawing 1100 TMC
- Available August-November only
- Srisailam water being used for Telugu Ganga, irrigation and for power.
- Nagarjunasagar - Not being used for irrigation of the originally
intended regions
|
|
5
|
- Short term plan (2 yrs)
- Long term plan (10 yrs)
|
|
6
|
- Proposed by Dr. Sriramakrishnaiah, then Technical advisor to Government
of Andhra Pradesh
- Connect Godavari and Krishna
- Lift irrigation - utilize existing rivers and major streams as water
carriers
|
|
7
|
- Start from Kaleshwaram below Pranahita and lift up to Krishna-Godavari
ridge in a number of stages
- Link canals connecting Akheru, Paleru, Yashwantapuram, Aleru and Musi
- Connect to Nagarjunasagar upstream
- Potential to draw 197 TMC at an average discharge of 419 cumecs
|
|
8
|
- 59 TMC @ 140 cumecs
- 1 TMC drinking water to Warangal city
- Lift at 32 stages and irrigate 7.58 lakh acres
- 378 MW (1226 million units) required for lifting
- Estimated cost is 1560 crore rupees
|
|
9
|
- Can extend scope to 4 times of original plan
- 59x4 TMC = 236 TMC
- Irrigate 25 lakh acres, only additional cost is power required for
lifting
- 378x4 MW = 1512 MW required for lifting
- Estimated cost is 1560 + 532x3 = 3156 crore rupees
|
|
10
|
- Meets the short term needs of the people
- Water only available June – November
- Will need reservoirs for year round availability. We need a long term plan
|
|
11
|
- Key points
- Build reservoirs and barrages on Godavari
- Create links to Krishna and create a water grid serving the needs of
the three regions of Andhra Pradesh all year around
- Harness waters of Vamshadara, Nagavali, Janjavati and champavati for
north coastal AP
|
|
12
|
- Two reservoirs
- Pranahita to KanthalpallI, about 105 km is mostly hilly and forest area
- Ideal location for reservoirs
- Propose one reservoir at Kaleswaram and the other at Kanthalapalli
(above Eturnagaram)
|
|
13
|
- Kaleswaram dam
- In line with the ridge between Pranahita and Indravati
- FRL – 135 m
|
|
14
|
- Inchampally not a suitable location
- At FRL 112.77 m, 60% submersion in Maharashtra and Chattisgarh and 40%
in Andhra Pradesh
- Reducing FRL to 105 m for reducing submersion will give only 100 TMC
- Instead, FRL of 105 m at Kanthalapalli will provide 300 TMC and reduce
submersion as well
|
|
15
|
|
|
16
|
- Construct 6 barrages along Godavari between Kanthalapalli and Polavaram
- Link 1 from Kaleswaram to Nagarjunasagar upstream
- Link 2 from upstream of Kanthalapally dam to the upstream of tail pond
below Nagarjunasagar
- Link 3 from upstream of Polavaram barrage to the upstream of Krishna
barrage
|
|
17
|
- Costs 37,000 crores
- 1500 MW required for lifting
- Must be taken up as a national project
- Planning sustainable river valley projects requires intricate
multidisciplinary study
- Can learn some other projects like Oswan dam in Egypt, 3 Gorges in China
|
|
18
|
- 550 TMC of water irrigates 30 lakh acres of Kharif paddy and 25 lakh
acres of Rabi
- 3000 MW generated at Kaleswaram and
Kanthalapally dams and Dummugudem, Polavaram and other barrages
on Godavari
- Power spent on lifting water to supply into the Krishna catchment area
can be recovered back at the check dams erected across the tributaries
of Krishna through hydel generating plants
|
|
19
|
- About 3 lakh pump sets currently in use can be substituted by Godavari
waters. This is a 450 MW saving (assuming 50% load factor)
- Full fledged water grid will meet the requirements of Karimnagar,
Warangal, Khammam, Nalgonda, West Godavari, Krishna, Guntur, East
Godavari and Vishakapatnam
|
|
20
|
- Krishna waters thus saved can be used
- For Mahbubnagar and Nalgonda by creating flood flow canal on Jurala
- 100 TMC to Rangareddy and Mahbubnagar through a project on Bheema
- 60 TMC to Nalgonda through SLBC
- 200 TMC can be released to Telugu Ganga, SRBC Veligonda etc to
Rayalaseema
|
|
21
|
- Hyderabad will continue to be on Madhava Reddy lift irrigation scheme
- Waters of Manjeera river will be released to irrigate Rangareddy, Medak
and Nizamabad
- 150 TMC of water during flood season (July to September) can be offered
to the south to solve the acute irrigation problem under Cauvery. A
reason for Central Government to take this up as a national project
|
|
22
|
- Harnessing the waters of Vamshadhara, Nagavali, Janjavati and Champavati
rivers would meet the requirements of North Coastal districts of AP –
Srikakulam and Vijayanagaram
