Difficulty: Easy
Correct Answer: Rakas (Rakshastal) lake in Tibet
Explanation:
Introduction / Context:
Major Himalayan rivers have distinct sources that are standard facts in Indian geography. The Sutlej (Satluj) is crucial for irrigation and hydropower, notably the Bhakra–Nangal project.
Given Data / Assumptions:
Concept / Approach:
The Sutlej's headwaters rise near Mount Kailash in western Tibet, specifically from Lake Rakshastal (Rakas Tal), adjacent to Lake Manasarovar but distinct from it. Many exam keys emphasize Rakshastal as the accepted source designation.
Step-by-Step Solution:
Identify the paired Tibetan lakes: Manasarovar and Rakshastal.Recall that Sutlej originates from Rakshastal; Manasarovar is the source of other headwaters in the region.Eliminate unrelated options like Bara-Lacha Pass (Chenab headwaters).
Verification / Alternative check:
Hydrographic references list the Sutlej as issuing from near Rakshastal (west of Manasarovar), flowing west–southwest into India through Shipki La.
Why Other Options Are Wrong:
Vering/Zanskar — not standard sources for Sutlej.Bara-Lacha Pass — associated with Chenab system (Chandra–Bhaga).Manasarovar — adjacent, but not the commonly cited Sutlej source; exam convention favors Rakshastal.
Common Pitfalls:
Confusing the two neighboring lakes; remember: Sutlej → Rakshastal.
Final Answer:
Rakas (Rakshastal) lake in Tibet
