When you break the Tigra Dam ( Moti Lake ) on the river Shank at Gwalior in Gwalior district in the Indian state of Madhya Pradesh there was on August 4, 1917 disaster in which about 1,000 people were killed.

The Tigra dam had been built in 1917 as gravity dam of masonry with lime mortar on a layered sandstone bedrock. It was founded about 60 cm deep in the bedrock and about 25 m high. The exact amount will vary, 24.7 or 25.9 m given as 24 m. The wall was 1.34 km long and the reservoir contained 124 million cubic meters of water. On the construction of the very well-known in India and significant hydraulic engineer Mokshagundam Visvesvarayya was decisive part.

The first filling of the reservoir, the dam broke during a flood when it was flooded. The dam was flowing over its entire length of 80 cm. It was calculated later that a water volume of 8500 m³ / s must be drained. Thus, the dam was up to 14 meters suspended on a length of 400 m as a whole. Two sections of the broken dam should be left standing as ruins today.

The dam was constructed in 1929 with design changes again, including with larger overflow openings. In 1970 there was again a failure case.
