It is a multipurpose project. The water is mainly used to irrigate agricultural land in the drought-prone Marathwada region of the state. It also provides water for drinking and industrial usage to nearby towns and villages and to the municipalities and industrial areas of Aurangabad and Jalna district. The surrounding area of the dam has a garden and a bird sanctuary. Location It is located on Godavari river at the site of Jayakwadi village in Paithan taluka of Aurangabad district in Maharashtra State state of India. History and significance A plan to build a dam on Godavari river in the drought-prone Marathwada region was first conceived during rule of state of Hyderabad . The plan was to build a dam in Beed district near village Jaikwadi (जायकवाडी) with storage capacity of 2,147 MCM (million cubic metres). The project came to know as Jayakwadi project after name of the village. However, after formation of new state of Maharashtra and comparative analysis on alternative places, it was decided to build a dam 100 km upstream at Paithan. The project was continued to name as Jayakwadi even after it was shifted to a new location. Building dam at higher level made it possible to have longer canals and thus providing irrigation facility to a larger region. The project proposal for this was completed by 1964.Although It was not natural Point Due to this Catchment area spread horizontally and Unnecessarily More people had shifted from their natives and well settled lives. The foundation of the dam was laid by the then Prime minister of India Lal Bahadur Shastri on 18 October 1965. The dam was inaugurated on 24 February 1976 by the then Prime minister Indira Gandhi. [3] The chief engineer of this project was Mr. A.A.A. Siddiqui. Dam Jayakwadi is one of the largest earthern dams in Asia. Its height is approx 41.30 m and length of 9,998 m (10 km approx) with total storage capacity 2,909 MCM (million cubic meters) and effective live storage capacity is 2,171 MCM. The total catchment area of dam is 21,750 km 2. There are total 27 water gates for the dam. In the year 2009 it has entered in 35th year of its life. It has in its lifetime overflowed only 17 times. On 10 August 2006 highest discharge of 250000 ft 3/s was recorded.in India of maharastra state district Aurangabad. Nath Sagar Jalashay Nath Sagar Jalashay is the name of the reservoir formed by Jayakwadi Dam. Fed by the Godavari and Pravara rivers the reservoir is about 55 km long and 27 km wide and spans over 350 km 2. Total submergence area due to the reservoir is approx 36,000 hectares. Unfortunately siltation has taken a heavy toll on the project. It is estimated that approximately 30% of the dam is filled with silt, reducing its life as well as storage capacity. Survey findings show that from 2003 to 2012, there was a loss of 31% (that is 8.08 thousand million cubic (TMC) feet) in dead storage and 14% (that is 10.73 TMC) in live storage capacity of the dam due to silt. Purpose Jayakwadi project is a multipurpose project. The main purpose was to irrigate land for agriculture in the drought prone Marathwada region of Maharashtra state. Other important purpose was to provide water for drinking and industrial usage to nearby towns and villages and to the municipalities and industrial areas of Aurangabad and Jalna. The 80% of water of dam is meant for irrigation, 5-7% for drinking water and the rest for industrial purposes. The average daily discharge of the dam is around 1.36 MCM, out of which 0.05 MCM of water is supplied to the MIDC area, 0.15 MCM is distributed to fulfil the needs of Aurangabad city, while the remaining amount is lost in evaporation. Irrigation Jayakwadi project is one of the largest irrigation projects in Maharashtra. Jayakwadi Dam irrigates cultivable area of 237,452 hectares in the districts of Aurangabad, Jalna, Beed, Ahmednagar and Parbhani through its left and right canals. The length of left bank canal is 208 km & the length of right bank canal is 132 km. The total command area is 183,858 hectares.
