It is an earth dam of 5.05 km bund length with a maximum height of 7.20 m and a surplus Regulator with three vents of 11.00 x 4.75 m. The design flood discharge is 495 m3 / Sec. (17480 Cusecs). The Reservoir holds up a volume of 6.422 m. M3(226.80 M.Cft) of Water at FRL condition ( + 33.250 m (or) 109.09 FT). The Project was completed during the year 1989.

The Ayacut of Sudhamalli Reservoir is 5080.62 Acres. Total dry ayacut is 3901.60 Acres. Total Wet Ayacut is 1179.02 Acres. The cost of the estimate works out to Rs. 1452.51 Lakhs.
