Panshet Dam, also called Tanajisagar Dam, is a dam on the Ambi river about 50 km (31 mi) southwest of the city of Pune in western India. The dam was constructed in late 1950s for irrigation and, along with three other dams nearby, Varasgaon, Temghar and Khadakwasla, it supplies drinking water to Pune. Panshet Dam burst in its first year of storing water on 12 July 1961, when the dam wall burst, because of the total absence of mandatory reinforced cement concrete (RCC) strengthening, [1] causing massive flooding in Pune. An estimated 1,000 people died from the resulting flood. [2]

Dam A barrier that stops or restricts the flow of surface or underground streams

A dam is a barrier that stops or restricts the flow of water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC.

Purpose

Attraction

Panshet is one of the famous picnic spots of Pune and attracts many visitors from Mumbai. The lake is made because of the backwater from the Panshet Dam; from the dam, tourists can see the Sahyadri mountains.

Western Ghats mountain range running parallel to the western coast of India

Western Ghats also known as Sahyadri is a mountain range that covers an area of 140,000 km² in a stretch of 1,600 km parallel to the western coast of the Indian peninsula, traverse the States of Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra and Gujarat. It is a UNESCO World Heritage Site and is one of the eight "hottest hot-spots" of biological diversity in the world. It is sometimes called the Great Escarpment of India. It is a biodiversity hotspot that contains a large proportion of the country's flora and fauna; many of which are only found in India and nowhere else in the world. According to UNESCO, Western Ghats are older than Himalayan mountains. It also influences Indian monsoon weather patterns by intercepting the rain-laden monsoon winds that sweep in from the south-west during late summer. The range runs north to south along the western edge of the Deccan Plateau, and separates the plateau from a narrow coastal plain, called Konkan, along the Arabian Sea. A total of thirty-nine areas including national parks, wildlife sanctuaries and reserve forests were designated as world heritage sites - twenty in Kerala, ten in Karnataka, five in Tamil Nadu and four in Maharashtra.

Panshet Water Park is a water sports center.

The Aswan Dam, or more specifically since the 1960s, the Aswan High Dam, is an embankment dam built across the Nile in Aswan, Egypt, between 1960 and 1970. Its significance largely eclipsed the previous Aswan Low Dam initially completed in 1902 downstream. Based on the success of the Low Dam, then at its maximum utilization, construction of the High Dam became a key objective of the government following the Egyptian Revolution of 1952; with its ability to better control flooding, provide increased water storage for irrigation and generate hydroelectricity the dam was seen as pivotal to Egypt's planned industrialization. Like the earlier implementation, the High Dam has had a significant effect on the economy and culture of Egypt.
