Indus River
Why in news?
- Pakistan has discovered massive gold reserves worth around Rs 80,000 crore in the Indus River bed, offering a potential economic boost to the country’s struggling financial situation.
About Indus River:

- The Indus River is one of the longest rivers in Asia, originating from a glacier near Bokhar Chu in the Tibetan region within the Kailash Mountain Range, close to Mansarovar Lake.
- It is known as ‘Singi Khamban’ (Lion’s Mouth) in Tibet.
- The river flows northwest and enters India at Demchok in Ladakh, where it courses between the Karakoram and Ladakh ranges before continuing into Pakistan.
- With a total drainage area of approximately 1,120,000 sq. km, it is one of the 50 largest rivers in terms of annual flow, estimated at 175 km³ per year (5,500 m³/s).
- The Indus River basin extends across Tibet (China), India, Pakistan, and Afghanistan, with India’s drainage area covering 321,289 sq. km (9.8% of India's total geographical area).
- It is bounded by the Karakoram and Haramosh ranges in the north, the Himalayas in the east, the Sulaiman and Kirthar ranges in the west, and the Arabian Sea in the south.
- The river is vital for agriculture, hydropower, and human consumption in the region.
- The Indus has several major tributaries. Its left-bank tributaries include the Zanskar River (Ladakh) and the Panjnad River, which forms from the confluence of five Punjab rivers—Jhelum, Chenab, Ravi, Beas, and Sutlej.
- Its right-bank tributaries include the Shyok, Gilgit, Kabul, Kurram, and Gomal rivers.
- The river originates from a mountain spring and is fed by glaciers from the Himalayas, Karakoram, and Hindu Kush ranges, supporting diverse ecosystems, from temperate forests to arid plains.
- Historically, the Indus River played a significant role in the Indus Valley Civilisation (3300 BCE - 1300 BCE), one of the world’s oldest urban cultures.
- Major sites like Harappa and Mohenjo-Daro are located in Pakistan, giving the civilisation its alternate name, the Harappan Culture.
Gold Reserves in the Indus River:
- Pakistan recently discovered vast gold reserves worth approximately ₹80,000 crore in the Indus River bed within the Attock district of Punjab province.
- This discovery was made through a government-commissioned survey and is expected to provide a significant economic boost to the country.
- The mining project will be overseen by NESPAK (National Engineering Services Pakistan) and the Mines and Minerals Department of Punjab.
- Geologists suggest that the Indus carries gold deposits from the Himalayas, accumulating as placer gold or nuggets.
- The State Bank of Pakistan valued the nation’s total gold reserves at $5.43 billion (December 2024).
- Amid economic instability, depleting foreign exchange reserves, and currency depreciation, successful extraction of these reserves could stabilise Pakistan’s economy and enhance its mining industry.

- The Dnipro River originates in Russia, in the low Valday Hills, located west of Moscow.
- Flowing southward for 1,368 miles (2,201 km), it passes through western Russia, Belarus, and Ukraine before emptying into the Black Sea.
- The river is divided among three countries, with approximately 300 miles flowing through Russia, around 430 miles traversing Belarus, and the longest stretch, about 680 miles, lying within Ukraine.
- The Dnipro River Basin spans an area of 504,000 sq. km, with 289,000 sq. km in Ukraine, covering 48% of the country’s landmass.
- This vast basin makes it one of the most significant river systems in Eastern Europe. Characterised by a gentle slope, slow flow, and an unstable riverbed, the river experiences fluctuating water levels.
- Along its course, the Dnipro passes through several major cities, including Smolensk and Dorogobuzh in Russia, Mogilev in Belarus, and Kyiv (the capital of Ukraine), Cherkasy, Dnipro, and Zaporizhzhia in Ukraine.
- Significance of the Dnipro River:
- Strategic Barrier: Historically, the Dnipro divided Ukraine into Right and Left Banks, influencing military and political conflicts, including during World War II and the ongoing Russia-Ukraine war.
- Economic Lifeline: It is Ukraine’s most crucial navigable waterway, supporting trade, agriculture, and hydropower generation.
- Geopolitical Importance: Given its location in a war-torn region, control over the river remains a strategic objective in conflicts, including Russia's attempts to secure key crossings in the ongoing war.
