The Tungabhadra Dam is a joint multipurpose project serving both irrigation and hydroelectric power generation for Karnataka and Andhra Pradesh.
The reservoir, known as Pampa Sagara, acts as a critical water source for the arid plains of the Raichur and Bellary districts.
The dam's construction involved the use of rubble concrete, a technique chosen for its structural durability in regional river conditions.
The site is located within a few kilometers of the UNESCO World Heritage site of Hampi, providing a contrast between modern engineering and ancient ruins.
The lighthouse structure serves as a navigational or signal marker for the reservoir's security and maintenance staff.
The Tungabhadra Dam Lighthouse Viewpoint provides an elevated vantage point overlooking the extensive reservoir and the massive gravity dam on the Tungabhadra River. The site is situated within the landscaped TB Dam Garden area, which includes the musical fountain and interconnected walking paths. From this height, visitors can observe the structural scale of the dam's spillway gates and the downstream canal network. The viewpoint serves as a primary observation deck for the water body, which covers an area of approximately 378 square kilometers at full reservoir level. It is positioned near the dam's main inspection road and offers views of the surrounding rocky outcrops typical of the Hampi region. The area remains a popular site for those touring the irrigation infrastructure of North Karnataka.

Bring polarized sunglasses to reduce the intense glare reflecting off the large reservoir surface.
Carry a wide-brimmed hat or umbrella as the viewpoint is completely exposed to direct sunlight.
Visit during the post-monsoon period when the reservoir is at its maximum capacity and the spillway gates may be operational.
Do not attempt to walk along the dam's service tunnels or restricted zones marked by signage, as security patrols are strict.
The area may be restricted during periods of high alert or severe weather conditions; check locally for potential seasonal closures of the upper deck.
Maintain a quiet demeanor as the site is part of a high-security irrigation zone; refrain from climbing on railings or restricted barriers.
