What are advantages and disadvantages of nagarjunsagar dam?
Advantages : 1. The dam at 408 tmc storage at a 509′ height (FRL) provides irrigation to 1.113 million acres on the right canal and 0.32 million acres at the left canal. It stabilises the irrigation downstream under the already built irrigation schemes. Rice, cotton, chillies, turmeric are the main crops under irrigation. Lake has enhanced ‘fisheries’ production. 2. The third largest man-made reservoir almost reaches the foot of the next higher Srisailam dam (for hydroelectric power generation) upstream. Water transport is made possible. 3. The dam generates ‘Hydel’ power. There is provision for pumping up the water back when the load is minimum (night time) because the water turbines can’t be shut off. It saves power generation capacity. 4. The reservoir and the ancient site university under Acharya (Prof.) ‘Nagarjuna’ was reclaimed and preserved atop a hill taht became an island in the lake. It has become an important tourist spot for history, Buddhist studies and nature-lovers. 5. I
