“The sun was so hot, we knew the floods would be coming.” Says Jagdish ji, resident of Lindur village in the Lahaul Himalayas.

His home and fields are adjacent to a glacial stream called Jahlma Nallah which shoots from the Pir Panjal range to meet the Chenab River below. And just as he predicted, on the afternoon of 29th June 2026, like the past five years[1], Jahlma Nallah flooded and roared. In a matter of minutes, the thin flow transformed into a terrifying, brown debris-laden force. The sludge raced towards Chenab and nearly blocked the river by the brute force of water and debris it collected on its way. It cut off the connectivity of hundreds of villages.[2]

A Sinking Village & a Stream that Floods in the Sun: Climate Change, Jahlma Nallah and Lindur in Chenab Basin

At the village of Jasrath in Lahaul and Spiti, the River Chandrabhaga’s current is swift and strong like a rambunctious toddler. The river is new here, birthed just 16 kms upstream at the confluence of the Rivers Chandra and Bhaga. Chandrabhaga will be named as Chenab only after a journey of about 400 kms downstream. Chenab is one of the largest tributaries of the River Indus whose expansive basin feeds over 250 million people in the heart of Asia.

Lahaul and Spiti district in Himachal Pradesh is a cold desert with very little rain, but the narrow ribbons of land along the Chandrabhaga are emerald with willows, apple orchards and cultivated farms. This is precious land.

“I’m going to buy vegetables from the banks of Ganga. Coming?” (“गंगेवर चालले आहे भाजी आणायला. येणार?”). This was my Grandmother’s Sunday morning ritual. I always jumped at the opportunity: it meant going to the local market skirting Ganga and staring at colorful heaps of vegetables, patting dewlaps of humongous cows settled in islands, stealing guilty glances at sadhus who sold fascinating stuff: owl claws, deer musk pods, Giant Entada seeds..but most of all, it meant observing the filthy and beautiful river from the Ghats. I lived in Nashik, on the banks of Godavari and Godavari was our Ganga. Continue reading “Ekti Nadir Naam: Ramblings through the etymology of River names in India” →
