Kathmandu— Rara Lake, Nepal's largest lake, has seen a 0.91-meter rise in water level from June/July to late August in fiscal year 2025/26, according to the Provincial Water and Weather Office in Surkhet, with no studies conducted to determine the threshold at which the lake could pose a risk to surrounding communities.

Rising Water Levels

The Provincial Water and Weather Office in Surkhet reported that Rara Lake's water level rose by 0.91 meters from June/July to the last week of August in fiscal year 2025/26, based on data from an automatic water-level monitoring device (radar sensor) installed at the lake.

Dr. Indira Kadel, chief hydrologist at the office, noted that the lake's water level increased by 0.8 meters during the same period in fiscal year 2024/25, with additional data showing a 0.3-meter rise from October/November to December/January in fiscal year 2024/25.

Authorities have yet to conduct a study to determine the dangerous water level threshold for Rara Lake, despite rising levels and local concerns about potential flooding.
