Picture a luxury yacht gliding past snow-dusted Himalayan ridges, kayakers threading through 45 kilometres of backwaters, and eco-lodges perched above a reservoir the size of a small city. Arunachal Pradesh Chief Minister Pema Khandu wants that vision to become reality — and on Tuesday, 10 November 2026, he convened a live discussion to map out exactly how.

The 40 sq. km canvas: what the Subansiri reservoir offers

The 2,000 MW Subansiri Lower Hydroelectric Project — one of India's largest hydro initiatives, developed by NHPC Ltd on the Subansiri river in Arunachal Pradesh — has long been defined by its power output. CM Khandu is now pressing a second case: the reservoir stretches across 40 square kilometres, fed by nearly 45 km of backwaters, and sits inside a Himalayan landscape of exceptional scenic and ecological richness. That physical canvas, he argued in the discussion, is precisely what a world-class hydrotourism destination requires.

The agenda covered boating, luxury yacht cruises, floating hospitality, water sports, adventure activities, and eco-tourism — a portfolio designed to draw visitors who might otherwise head to international mountain-lake destinations. The reservoir's status as a Golden Mahseer habitat adds a rare, niche hook for sport-fishing and conservation tourism.

Who was in the room — and why it matters

MLA Rotom Tebin, who represents a constituency in the Subansiri region, joined the Chief Minister for the live session, alongside Ninong Ering, Advisor to the Minister for Hydro Power Development in Arunachal Pradesh. Ering, a former Member of Parliament from the state, brings both political weight and institutional knowledge of the hydro sector to any tourism conversion conversation. Tourism and adventure-destination development experts also participated, signalling the state's intent to move beyond concept and into structured planning.

Arunachal's broader bet on reservoir diversification

This discussion fits a pattern that has been building across the Northeast. Arunachal Pradesh holds some of India's most substantial untapped hydropower resources, but large dam projects have historically been justified on power-generation metrics alone. Layering tourism onto completed or near-complete reservoirs offers state governments a second economic argument for infrastructure that took decades and significant ecological trade-offs to build.

Similar reservoir-tourism concepts have been tested in other Indian states with major dams, but the Subansiri site's Himalayan setting, biodiversity credentials, and sheer scale give it a differentiated pitch. The Golden Mahseer — a prized freshwater fish endemic to Himalayan river systems — could anchor a conservation-tourism narrative that appeals to both domestic and international travellers.

From live discussion to policy: the next step

The Chief Minister described the session as 'the central idea of our discussion on the hydrotourism potential,' framing it as a planning milestone rather than an announcement of completed infrastructure. What follows — detailed project reports, tourism policy amendments, private operator empanelment, environmental clearances for water-sport activities — will determine whether the Himalayan reservoir becomes Arunachal's next signature destination or remains a compelling idea on a whiteboard.

Arunachal Pradesh has the landscape, the water body, and now the political attention at the top. The question is whether the state can convert a live discussion into a live destination before rival mountain tourism circuits elsewhere in the region get there first.
