The Budhigandaki River is a major river in central Nepal, known for its steep valleys, powerful currents, and pivotal role in Nepal’s future energy plans. A tributary of the Gandaki River system, the Budhigandaki flows through rugged Himalayan terrain and is the proposed site for one of Nepal’s most ambitious infrastructure projects — the Budhigandaki Hydropower Project.

Quick Facts

• Origin: Glaciers near Manaslu and Ganesh Himal, Gorkha District

• Length: Approx. 120 km (75 miles)

• Mouth: Joins the Trishuli River near Benighat, forming part of the Gandaki system

• Key Districts: Gorkha and Dhading

• Known For: Hydropower potential, trekking routes, and deep gorges

Geographic and Hydrological Profile

Source and Flow

The Budhigandaki River originates from snow-fed glacial zones in the Himalayan foothills, including Mount Manaslu (8,163 m). It flows southward, cutting through steep and remote gorges before merging with the Trishuli River.

River Basin Role

• Part of the Gandaki River Basin, which ultimately drains into the Ganges

• Glacial-fed with high discharge during monsoon seasons

• Supports local irrigation and fisheries in mid-hill regions

Budhigandaki Hydropower Project

Nepal’s Megaproject

The Budhigandaki Hydropower Project is a planned 1,200 MW reservoir-type hydropower plant — one of Nepal’s largest proposed energy developments.

Project Highlights:

• Type: Reservoir (storage)

• Location: Benighat-Rorang area, Dhading and Gorkha districts

• Estimated Cost: Over USD 2.5 billion

• Displacement: Over 45,000 people (due to reservoir flooding)

• Benefits:

  • Energy independence for Nepal

  • Long-term power storage and grid stabilization

  • Flood control and water management

Challenges and Controversies

• Environmental impact: Potential loss of forests and biodiversity

• Social issues: Displacement of residents, land compensation disputes

• Funding debates: Delays in financing, with various discussions involving foreign and national investors

Cultural and Regional Significance

Trekking and Indigenous Culture

The Budhigandaki River is a gateway to Manaslu Circuit Trek, one of the most scenic and culturally rich trekking routes in Nepal. Along the river, you’ll find:

• Traditional Gurung and Tamang villages

• Ancient monasteries and terraced farmlands

• Remote, culturally preserved regions that reflect Himalayan life

Environmental and Ecological Context

River Ecosystem

The Budhigandaki supports a diverse ecological zone:

• Snow-fed aquatic habitats

• Home to migratory birds and cold-water fish species

• Crucial for biodiversity corridors between Langtang and Annapurna

Concerns

• Sedimentation and erosion in steep catchments

• Glacial melt and climate change threatening flow patterns

• Hydropower reservoir potentially impacting water quality and sediment load downstream

Conclusion

The Budhigandaki River stands at the crossroads of natural beauty, renewable energy development, and cultural richness. While its future is tied to ambitious infrastructure plans, careful planning, and sustainable practices will be key to ensuring that both people and the environment benefit from its powerful flow.
