10/31/2018 District Irrigation Profiles IRRIGATION PROFILE OF SPSR NELLORE DISTRICT *Click here for Ayacut Map INTRODUCTION The Population of the District is 29.66 lakhs (Census 2011). The main rivers, which flow in the District, are Pennar and Swarnamukhi. Other streams that are occasional and torrential in character are Kandaleru, Boggeru, Beeraperu, Royyalakalva, Tsallakalva, Mamidikalva, Chippaleru and Kalangi etc., All these rivers and rivulets will bedry for major part of the year and carry heavy flash floods during rainy season. The Pennar river is the most important river and it is a boon to the eastern half of the mandals in SPSR Nellore and Kavali Revenue Divisions.

Pennar Delta Preamble The Pennar river Canal system was established during the British Regime. The Pennar Delta system comprises of two systems viz., SangamAnicut system and SPSR Nellore Anicut system. Trough the two systems are distinctly separated by the River Pennar, the entire system is to be reconed as one, since the supplies to the both the systems are from Pennar River only. The network of Pennar River canal system are compact and studded with subsidiary tanks. Prior to the construction of the two Anicut, these tanks were filled through open channels from the river during the floods. Principal storage reservoirs are Kanigiri Reservoir and Nellore tank in Sangam Anicut system and Survepalli Reservoir in Nellore Anicut system. Besides these reservoirs, there are several tanks in both the systems. The total ayacut contemplated under Pennar Delta is 1,75,000 Acres and the http://irrigationap.cgg.gov.in/wrd/getDistricts 2/16 10/31/2018 District Irrigation Profiles extent of ayacut developed is 2,47,000 Acres. The modernization of Pennar Delta system was taken up under "Jalayagnam Programme" by theGovernment of Andhra Pradesh and the same is in progress. Salient Feature IP Created : 2,47,000 Acres 1.

Sangam Barrage Cum Bridge Preamble Sangam anicut was constructed across Penna river during 1882-1886 contemplating to supply water to SPSR Nellore tank supply channel and Kanupur canal on right side and Duvvur canal, Kanigiri main canal and Kavali canal on left side. This anicut is the life line for the irrigation of about 3.85 lakh acres now being irrigated. The following are the details of ayacut fed with the water from Somasila reservoir. 1) Penna delta : 2.47 lakh acres 2) Kanupur canal : 0.63 lakh acres 3) Kavali canal : 0.75 lakh acres Total : 3.85 lakh acres Sangam anicut was constructed across Penna River during 1882-1886 http://irrigationap.cgg.gov.in/wrd/getDistricts 3/16 10/31/2018 District Irrigation Profiles During course of time thousands of acres of additlonal ayacut was brought into cultivation. It has became a regular practice to increase the water level by 0.90 mtrs., above crest level of Sangam anicut by providing sand bags of 1.20 mtrs., height over the crest for the entire length for providing commandability to the existing ayacut under Kanupur and Kavali Canals. This practice of placing the sand bags over the crest of anicut is resulting in recurring cost in lakhs of rupees for Government every year. Unless the anicut is replaced by a new one, the anicut is likely to prone for breaching due to over age (crossed 100 years). Salient Feature Catchment area : 50,122 sq.km.

Nellore Barrage Cum Bridge http://irrigationap.cgg.gov.in/wrd/getDistricts 4/16 10/31/2018 District Irrigation Profiles Preamble The Penna river canal system consists of the Nellore Anicut system and the Nellore tank, together with the Sangam anicut system. The oldest reservoir under the Penna is the Nellore tank which originally received its water by a channal taken off from the river in the neighbourhood of Mulumudi and which also acted as a catch channal to receive the water of the Ludums which raise near Aiyagaripalli, Podalakur etc., In 1854-55 the Madras Governement constructed the anicut at SPSR Nellore across the river to secure certain supply of water for all the tanks in the Southern delta and also sanctioned improvements to the Nellore tank. After few failures the present structure was designed by the famous Engineer Sir Arthur Cotton and was completed in 1862-63 and has stood admirably. The crest of the anicut is 9.61 feet above the bed of the river and 42.55 feet above the sea level and its length is 2,040 feet. In place of it the new structure is proposed and the salient features of the proposed structrure are as follows.
