The Independent Power Producers Association of Nepal (IPPAN) has called on all hydropower projects across the country to remain on high alert for the next few days in light of a forecast of heavy rainfall.

The Department of Hydrology and Meteorology has predicted intense rainfall across the country on July 19, 20, and 21. Following an agreement between IPPAN and the Department to share early flood warning information, the Department has been regularly communicating updates to IPPAN to support disaster preparedness.

“The Department has predicted heavy rainfall in eastern Nepal from the evening of July 19 to the morning of July 21,” read a statement issued by IPPAN on Friday.

Rivers in eastern Nepal—including the Koshi, Tamor, Arun, Tamakoshi, Dudhkoshi, and Kankai—are expected to see a significant rise in water levels, with the Koshi River potentially reaching or exceeding the danger mark. The weather system is expected to move westward, with impacts likely to be felt in the Bagmati River, affecting the Kathmandu Valley and lower surrounding areas. The Mahakali River and its adjacent regions are also expected to face flooding by the afternoon of July 21.

According to IPPAN, districts such as Baglung, Myagdi, Parbat, Syangja, Palpa, Nawalparasi, and Rupandehi—located along the Narayani watershed—are likely to be affected. Moderate impacts are also anticipated in the Rapti and Babai river regions in western Nepal.

IPPAN has urged all hydropower projects—both operational and under construction, including those affiliated with the organization—to adopt precautionary measures to minimize possible human and material losses due to the anticipated weather events.

The association also recalled the July 8 flood in the Bhotekoshi River, which caused significant damage to more than half a dozen hydropower projects in Rasuwa and Nuwakot districts. Emphasizing the need for heightened vigilance, IPPAN warned against repeating such past incidents. -- RSS
