Sayaji Sarovar, also known as the Ajwa lake, is located 22 km away from the main city of Vadodara. Formed by damming the Surya River and Vaghali Nala, the Sayaji Sarovar is the principal source of water in Vadodara. The site was designed by Shri Jagannath Sadashiv, and was constructed between 1885 and 1890. Sprawling across an area of 190 sq. km, this reservoir is 5 km in length and can store water to the height of 212 ft.
Near the earthen dam is a beautiful garden, which is patterned similar to the famous Brindavan Gardens of Mysore. A major attraction of this garden is the illuminated fountains that operate on every Saturday, Sunday and Monday. Featuring boating facilities, this reservoir is often used by the locals as well as tourists for picnic purposes. Travellers can reach the site of this dam by hiring an auto rickshaw or renting a private car.
