India's first riverine lighthouses are being set up on which river?
- A.Ganga, National Waterway-1
- B.Brahmaputra, National Waterway-2
- C.West Coast Canal, National Waterway-3
- D.Godavari, National Waterway-4
Correct answer
Explanation
The correct answer is the Brahmaputra, National Waterway-2. Four riverine lighthouses, the first of their kind on an inland waterway in India, are being built at Pandu, Bogibeel, Silghat and Biswanath Ghat under a ₹74 crore project announced in March 2026. Each will stand 20 metres above ground, with a geographical range of 14 nautical miles and a luminous range of 8 to 10 nautical miles, and will run on solar power. Option A is wrong: the Ganga system is National Waterway-1 and carries River Information Services, not the first lighthouses. Option C is wrong because National Waterway-3, the West Coast Canal in Kerala, uses 312 lighted buoys and 17 beacon lamp posts instead. Option D is wrong because the lighthouse project is tied to the Brahmaputra, which runs 891 km from Dhubri to Sadiya and is the longest navigable stretch in the country.
