Anantasagaram is an old reservoir in Anantapur. In fact, the city derived its name from the same tank. Acclaimed as one of the biggest reservoirs in the district, Anantasagaram occupies an area of 2,511 acres in Anantapur and Bukkarayasamudram. A fraction of the tank is known as 'Musalammakatta' and it is said to be named after Musalamma (a lady from Bukkarayasamudram), who sacrificed herself to seal the breach in the tank.
