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 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.
