ABSTRACT:
A FEASIBLE LINK PROJECT OF NATIONAL IMPORTANCE HAS BEEN SELVED AWAY. IT IS A NATURAL GRAVITY LINK CANAL PROJECT BETWEEN MAHANADI AND GODAVARI RIVERS. CENT PERCENT WATER SCARCITY WOULD BE AVOIDED IN THE ORISSA AND ANDHRA PRADESH. AN IRRIGATED LAND OF ABOUT 3.7MILLION HECTARES MAY BE ACHIEVED. HYDEL AND SUB-RESERVOIRPROJECTS CAN BE BUILT. DEPENDENCE ON GROUND WATER RESOURCES FOR IRRIGATION MAY BE AVOIDED. THE USE OF ELECTRIC POWER FOR UNDERWATER RESOURCES CAN BE AVOIDED.

PREAMBLE:
During the years 1996 -2000 a survey has been conducted and viability of the project was adjudged to be extremely beneficial. The returns on the project can be recouped within a period of about four years.
Main concept of the project is to link the surplus water flowing away into the sea in Mahanadi of Orissa State, which may be diverted to join the Godavari River at the upper-stream near at the Vamsadara project. It flows above Yeleru reservoir project and joins the Godavari. It is more suitable for the rain fed areas of the Orissa state and Srikakulum, Vijayanagaram, Visakhapatnam and East Godavari District. It meets the complete irrigation water needs of the cultivable lands in these four districts. In addition the project meets the water needs of the Industries, drinking water and avoids the need of the Wasting electric power for taping underground water, by way of use of Bore pumps. All the dry lands of these four districts can be totally irrigated. The water flows from 30-70 meters down the slope under gravity. This allows several feeder canals to be interlinked with the gravity downward flow.
National Water Development Agency proposed in the National perspective Plan under Peninsular rivers development component to transfer surplus flows of Mahanadi to Godavari system and to further transfer to water the short Krishna, Pennar and Cauvery rivers. This would enable irrigation of drought prone areas lying in Orissa, Andhra Pradesh and Tamil Nadu.
These proposals of inter basin transfers, after involving several thousands of cores of rupees, when completed, quench the thirst of water scarce population ,irrigate parched lands besides meeting the Industrial water needs in Orissa, Andhra Pradesh and Tamil Nadu states almost cent percent.
MAHANADHI-GODAVARI LINK PROJECT:
Pre feasibility report of Mahanadi-Godavari link projet has been completed and detailed surveys for 932 km link have already been started and were thought to be completed by 1999. The link canal with a bed width of 57m and depth of 7m with a F.S.L of 74m traverse through chronic water scarce areas in Orissa and in Srikakulum. Vijayanagaram, Visakhapatnam and East Godavari Districts of Andhra Pradesh and meets enroute irrigation Bhubaneswar-Cuttack-Ganjam districts. Beginning at Manibhadhra reservoir links cotton barrage. With 74 m height gradient reducing to about 13.91 meters height at the cotton barrage. The link canal touches Rushikaulya-Basuda (partly in Orissa and in Andhra) Sarada, Pampavati Thandava etc Rivers and rivulets. It has only 7m depth at starting point in Manibadhrapur reservoir. It would have a terminal area in Visakhapatnam near Simhachalam with a height of about 7 m.
Irrigation to about 3.7 lacks of hectares’ with areas in Mahanadi, Vamsadhara and irrigates Ganjam and Kurda districts. Has a Hydel power project scope at Manibhadra-Pamovathi areas. Other reservoirs can be built enroute.
Estimated in 1989-90 as about 3416 crores. It runs below Yeleru reservoir ayacut and caters to the needs of coramandal areas.
Preliminary report completed in 1993-94. Would help the water scarce Amravati and Amalapuram areas to dispense with salty drinking water of Godavari adjoining Bay of Bengal. Detailed survey was made in 1994-1997. Project was anticipated to be completed in AD2000.Discharge from Mahanadi 627MCM/sec water to the canal. Discharges about 435CMC/sec at Cotton Barrage.
IT IS A NATURAL GRAVITY LINK CANAL PROJECT. Without the need to pump up the water at any stage of the link canal. Up to anticipated 7000MCM/sec of this MG water available throughout the year. About 11,788 MCM water transferable from river Mahanadi and balance to Manibhadra Canal areas of about 3000CMC. Enroute areas to Godavari expected 577CMC of water supply.
The Technical Assessment Committee and the National Water Development Agency (under Union Ministry of Water Resources) have all the data available with them. Politicians busy with their endeavours should pay attention to projects of National Level importance and benefit.
SURPLUS WATER:
1. Icchahalli 20,000MCM to Nagarjuna Sagar
2. Polavaram 15000 MCM
3. River basins cultivation
a. Vamsadara 103237 hectares
b.Nagavalli 127917 hectares.
c. Stream Nagavalli and Godavari 251978 hectares.

ACKNOWLEDGMENT:
The irrigation studies made by (Late) Dr.K.L.Rao former Union Minister, Government of India, have inspired me as a journalist to prepare these articles for the benefit of General Public in the Districts of AP, TN, and Orissa states. The map above shows his thoughts.
