                    Water is a precious resource. It is vital for realizing the full potential of agricultural sector. Optimum development and efficient utilization of water resources both surface and ground water, therefore assumes great significance. The district has 2,16,403 hectares of cultivable land. 49,907 Ha. of  irrigation potential has been created through  different sources , as presented below. 

01.       MAJOR IRRIGATION

RENGALI MULTI PURPOSE PROJECT

Rengali multi purpose project has been constructed to provide Power Generation, Flood Control and Irrigation facilities. The main component of the project is a masonry gravity dam of   1040 Mt. length, with a maximum height of 75M across river Brahmani near village Rengali in Angul District. 

          The live storage capacity of the reservoir at F.R.L. is 3412 million cubic meters and its water-spread area at M.W.L. is 414.08 Sq. Km. There is a dam foot powerhouse with installation capacity of 250 MW, 5 units of 50M.W. each. The discharge from each unit varies from 140 cumecs to 170 cumecs. 

          Through reservoir routing the flood havoc in Dhenkanal, Jajpur & Kendrapara Districts   has been redressed significantly. The over all cost of the dam and powerhouse was Rs.200 crores approximately. 

SAMAL BARRAGE 

          In stage-II construction of Rengali multi purpose Project a barrage has been constructed at Samal. The water released from the Rengali power house is picked up in the Barrage at about 35Km. down stream of the dam to provide Industrial water use and extend irrigation facilities on either bank of the river in an area of 3,36,400   Ha. lying in Angul,  Dhenkanal, Cuttack, Jajpur & Keonjhar districts.

The length of the barrage is 533.40M having two head regulators on either side having discharge capacities of 270.00 cumecs & 140.37 cumecs respectively. The cost of   construction of the barrage proper was Rs. 60.00 crores. The canal net works are under construction.

02.       MEDIUM IRRIGATION

DERJANG IRRIGATION PROJECT 

          The Derjang Irrigation Project is a reservoir scheme constructed across river Ningara & Matalia near village Majhika in Angul Block. The catchment area is 399 Sq.Km at reservoir The main canal is 13.19 Km. having    33 nos. of minors & sub-minors. This project is having C.C.A of 7392 Ha. in Kharif including recent extension ayacut of 8 nos. of minors executed under NABARD assistance (RIDF – I).

          Previously the canals were unlined earthen canals. So after constant use it could not supply water to its full capacity. Hence in the year 1995-96, the project was included under Water Resources Consolidation Project (WRCP) to achieve its full capacity at an estimated cost of Rs. 352.70 lakhs & the work was completed in the year 2002-03.

          Farmers are being involved in operation & maintenance of the canal system, through Water Users Associations, known as Pani Panchayats. The entire command area has been divided into 17 chakas. One WUA has been formed in each chaka. 13 chakas have been handed over to 13 no. of WUAs. The remaining area will be handed over to 4 WUAs soon. The WUAs have been federated into an Apex Committee.   

The prevailing cropping pattern as decided in consultation with  the local farmers, Department of Agriculture has been engaged to determine the crop water requirement of the project for different months during khariff water supply & accordingly a detailed O & M Plan of the canal system is worked-out to guide the Pani Panchayats for smooth operation & management of the canal system. 

              At present the Pani Panchayats are provided  a grant-in-aid of Rs. 35/- per Ha. for maintenance of the canal system which is likely to be increase  to Rs.100/- per Ha.   Government of Orissa has issued guide lines for utilisation of O & M grant & its distribution.

AUNLI IRRIGATION PROJECT 

          The Aunli Irrigation Project is a diversion weir scheme constructed across river Aunli near village Kanaloi  in Chhendipada Block of Angul District. The catchment area is 150 Sq.Km at weir site. The major component of this system consists of diversion weir of 56 mtr. length with automatic falling shutters of 0.9 mtr. height. The main canal is 4.656 Km. having 8 Nos. of Minors & Sub-Minors. This project was completed in 1987-88 at a cost of Rs.299.87 lakhs. This project is having C.C.A of 1746 Ha. in Kharif & 300 Ha. in Rabi.         

Previously the canals were unlined earthen canals passing over sandy zone. So after constant use & due to lack of proper maintenance, it could not supply water to its full capacity. Hence in the year 1995-96, the project was included under Water Resources Consolidation Project (WRCP) to achieve its full capacity at an estimated cost of Rs. 310.38 lakhs. Farmers organisation and turnover programme was introduced in Aunli Irrigation Project Area during March 1998 as a Pilot Scheme. The purpose of the scheme is for optimum use and equitable distribution of Irrigation water through participation of farmers in operation and maintenance of canals as well as water management. For this purpose four nos. WUAs have been formed in the command area. The canal system under SIFT component of Orissa Water Resources Consolidation Project was handed over to the farmers for its operation & maintenance as per FOT guidelines. An APEX Committee has been formed    to facilitate the activities of Pani Panchayat. One Pani Panchayat has been formed with only women farmers as members. The success story of these Pani Panchayats has received good attention. Farmers from all parts of the state visit this project to get a feel of the success of the Pani Panchayats.         

The prevailing cropping pattern as decided in consultation with the local farmers, Department of Agriculture has been engaged to determine the crop water requirement of the project for different months during agricultural season   & accordingly a detailed O & M Plan of the canal system is worked-out to guide the Pani Panchayats for smooth operation & management of the canal system.         

MANJORE IRRIGATION PROJECT 

          Manjore Medium Irrigation Project is a reservoir scheme being constructed across river Manjore near village Manarbeda of Athamallick sub-division.The catchment area is 452.00 Sq. Kms. at reservoir site. It envisages construction of one 2050Mt long earth dam with a central spillway of   180M long and 6M high dyke near left abutment. There are two head regulators on either side of the river with a network of canal system to provide irrigation facility to 6090 Ha. during Kharif & 4335 Ha. during Rabi after its completion. 

          At present the balance works such as excavation of canal networks, periphery road construction & river gap closing is going on. It has been targeted to start irrigation water supply during July’2003. In the first stage the project will supply irrigation for 2300  Ha. in Kharif.    

03.       MINOR IRRIGATION PROJECTS 

           There are 52 Nos. of completed Minor Irrigation Project in Angul District out of which 34 nos. are diversion weirs and 18 nos. reservoirs. The design ayacut of the above 52 nos. M.I.Ps  is  15602.00 Ha. ayacut in Kharif  & 2838 Ha. in Rabi. The certified ayacut of the above M.I.Ps  is  12770 Ha. in Kharif.

          There are 21 partly derelict M.I.Ps in Angul District, whose designed ayacut is 1912 Ha. & certified ayacut is 826 Ha.

          Besides, there are 95 completely derelict M.I.Ps whose designed ayacut is 7296 Ha.
