The incessant rains of last July caused severe flooding in Dordi Corridor and Seti River. Most of the hydropower projects under construction were badly affected. The floods in Melamchi also caused problems in the Melamchi Drinking Water Project, a project of national pride.

The Bhotekoshi Hydropower Project was shut down for almost four years due to floods in the Bhotekoshi River a few years ago. Last July’s floods alone caused a loss of about Rs 3 billion in the energy sector. In the last three years alone, floods have caused a loss of Rs. 6 billion in the energy sector. The project was made safer by lowering the waters of the Upper Tamakoshi Reservoir last August when heavy rains fell in Tibet, an autonomous region of China, the upper reservoir of the Tamakoshi River.

 Due to climate change, the melting of glaciers in the Himalayan region has increased. Similarly, heavy rains fell in Manang, Bajura, Bajhang and other Himalayan regions last July. Good efforts have been made by the government and non-government sector to reduce the water level in Chho Rolpa Lake. There are more than three dozen small and large glacial lakes in the upper reservoir area of ​​Bhotekoshi alone.

Many glaciers and lakes have also started appearing in the Solukhumbu area. Glaciers and glaciers are increasing in size as global temperatures rise. As a result, the risk is increasing in the lower coastal areas. Dozens of sheep and goats have been swept away by a recent avalanche in Mustang.

A few years ago, a sudden flood in the Seti River in Kaski caused great loss of life and property. Most of the rivers and streams of Nepal flow from north to south and are vertical in nature. The water level in the river is rising due to the rise in temperature. This has increased the risk in the hydropower projects constructed on the river.

According to Sandeep Shah, an energy entrepreneur who worked on the foreign-invested Khimti and Bhotekoshi hydropower projects, a study of satellite data after the construction of the projects in 1990 found that there were about 40 glaciers in Chinese territory. He said that the Bhotekoshi Hydropower Project has been constructed by studying the details of major floods in those rivers even in 1930 and 1981.
