It is in the Indian state of Tamil Nadu. This Dam is the oldest in India which is still in use. The idea behind the 2,000-year-old Dam was to rinse the delta districts for paddy cultivation. During this time, the Dam irrigated 699,000 acres of land. In the 19th century, the Dam went through a phase of British reconstruction. By the twentieth century, the Dam was irrigating about 1 million acres. There is ongoing controversy over whether the Dam is older than he expected.

3. Cornalvo Dam, Spain (1st or 2nd century)

Cornalvo Dam is a gravity dam built by the Romans around the 1st or 2nd century AD. It has been in effect ever since. The Dam is in Extremadura, Spain. It is an earthen dam with stones in the water. Cornalvo Dam is part of the Merida Archaeological Ensemble, a UNESCO World Heritage Site since 1993. This Dam extends to Albarigas (Guadiana Basin). It stands 24 meters high and 194 meters long. It was the highest Dam outside of Italy at that time. The uninterrupted Dam is the main source of water supply in the town of Merida.

4. Saimaik Dam, Japan (circa 7th century AD)

The Siamese Dam is one of the most valuable dams that brings out amazing Japanese water engineering techniques. It is one of the oldest dams in the world. The Dam is located in Osakasayama, Osaka Prefecture, Japan. It was built around the 7th century AD. The 1,400-year-old Dam has a museum to give credit and respect. The Dam has a capacity of 2.8 million meters and is located on the banks of the Nishiyok River. Several historical figures from Japan have renovated the Dam. Some of these figures are historical figures such as Goki, a Buddhist priest from the Nara period, Chogen, a Buddhist priest from the Kamakura period, and Katagiri Katsumoto, a samurai from the Edo period.

According to estimates, the Dam was extended by the Roman Empire around 284-305. The Roman emperor Diocletian built the structure for irrigation. Its capacity is 90 million m³ ³ Lake Holmes Dam, or Quattinaঃ Barrage was probably the largest reservoir in the Near East. It is noteworthy that the Dam had very low ceilings since then. The two-kilometer long Dam is a gravity dam made of Roman concrete core and basalt blocks. Currently, the Dam has a capacity of about 200 million m³.
