The Karnali Chisapani Hydropower Project: Navigating Nepal’s River of Contrasts

Nepal’s Karnali River, renowned for its pristine waters and exhilarating Class IV–V rapids, stands at a pivotal crossroads. The proposed Karnali Chisapani Hydropower Project threatens to transform this last free-flowing river into a reservoir, potentially altering its very essence. As passionate advocates for responsible adventure tourism, Nepal River Runner delves into the multifaceted impacts of this mega-project, exploring both the challenges and opportunities it presents.

Project Overview: Ambitions and Realities

The Karnali Chisapani Hydropower Project, envisioned as South Asia’s largest hydropower initiative, aims to harness the immense potential of the Karnali River. With an estimated capacity of 10,800 MW and a projected cost of NPR 1.147 trillion, the project is poised to significantly bolster Nepal’s energy infrastructure .

However, this ambitious plan comes with profound implications for the river's ecosystem and the communities that depend on it.

The Karnali River: A Rafting Paradise

Spanning 507 kilometers, the Karnali River offers one of Nepal’s most sought-after rafting experiences. Starting from Mount Kailash in Tibet, it meanders through remote jungles, providing adventurers with thrilling rapids, serene beaches, and abundant wildlife. Notable sections include:

• Dhungeshwor to Chisapani: A 10-day expedition featuring iconic rapids like Sweetness & Light and God’s House .

• Seti Karnali: A 12-day journey combining rafting and fishing, culminating at Chisapani .

These sections are celebrated not only for their technical challenges but also for the untouched natural beauty they traverse.

Impacts of the Chisapani Project on Rafting

i. Submersion of Iconic Rapids

The proposed reservoir, extending approximately 167 kilometers, threatens to submerge key rafting sections, including:

• Sweetness & Light (IV)

• God’s House (V)

• Jailhouse Rock (IV)

These rapids, formed by steep gradients and exposed boulders, are unlikely to survive the inundation. The loss of such features would mark a significant blow to Nepal's white-water rafting offerings.

ii. Altered River Dynamics

The creation of a reservoir would flatten the river's gradient, reducing flow velocity and diminishing the turbulent features essential for rafting. Even with controlled releases, the natural rhythm of the river would be disrupted, leading to less dynamic and potentially less safe conditions for adventurers.

iii. Ecological Consequences

Beyond rafting, the project poses risks to the river's biodiversity. The Ganges river dolphin, Nepal's last viable population, inhabits the Karnali's upstream sections. The construction of a high dam could eliminate their habitat, pushing this endangered species closer to extinction .

Potential for Sustainable Coexistence

While the challenges are significant, there are pathways to balance energy development with ecological and recreational values:

• Adaptive Flow Management: Implementing controlled water releases during peak rafting seasons can help maintain downstream flows, preserving some rafting opportunities.

• Environmental Impact Assessments (EIA): Comprehensive EIAs can guide the development process, ensuring that critical habitats and recreational areas are protected.

• Community Engagement: Involving local communities in decision-making processes can lead to more sustainable and accepted project outcomes.

  
  

A Call to Action: "Let's Ride the Last Free-Flowing River"

As stewards of Nepal's natural heritage, it's imperative to advocate for a balanced approach that considers both development and conservation. The Karnali River is not just a source of energy but a lifeline for countless species and communities, and a haven for adventurers worldwide.
