Geography

[edit]
Nagarjuna Sagar Dam

This reserve is located between longitude: 78°30' to 79°28' east and latitude: 15°53' to 16°43' north. Elevation varies from 100 m (330 ft) to 917 m (3,009 ft) above mean sea level.

Average annual rainfall is 1,000 mm (39 in).

The hill ranges contain a number of plateaus, of which, Amrabad, Srisailam, Peddacheruvu, Sivapuram, and Nekkanti are noteworthy. Nagarjunasagar receives rains from the southwest monsoon, which is active from the second half of June to the end of September. The Krishna River cuts its basin almost 200 m (660 ft) deep over a distance of 130 km (81 mi) through the reserve. There are several waterfalls in the reserve such as the Ethipothala Falls, Pedda Dukudu, Gundam and Chaleswaram.[2]

Ancient history

[edit]

The ancient temples at Srisailam of Lord Mallikarjuna and his consort goddess Bhramaramba, an incarnation of Parvathi as the fair-complexioned boon from Brahma, contain one of the twelve sacred Shaiva Jyotirlingas and one of the eighteen Maha Shakthi peethas in India.

This area contains ruins of Nagarjuna Viswa Vidyalayam. The site was once the location of many Buddhist universities and monasteries.

The ruins of a fort of the 3rd century BCE Indian ruler, Ikshwaku Chandragupta overlook the Nirjivapuram (Lifeless city) valley. The ancient fort of king Pratap Rudra of the Kakatiya dynasty and several other forts are visible on the banks of the Krishna River. An ancient 105 mi (169 km) wall constructed there by the Kakateeyas is an impressive historic feature.

This area contains several rock shelters and cave temples including: Akka Mahadevi Bhilam, Dattatreya Bhilam, Umaa Maheswaram, Kadalivanam, and Palankasari.[2][3][4]
