🧠 Classroom Explanation

Didwana, Kuchaman, Sargol and Khatu are towns associated with saline (salt-water) lakes, primarily located in Rajasthan, a state marked by:

• Inland drainage
• High evaporation
• Low rainfall
• Accumulation of salts in closed basins

---

🧂 Saline Lakes of Rajasthan

• Didwana Lake
  • Located in Nagaur district
  • One of the important salt-producing lakes of Rajasthan
• Kuchaman Lake
  • Also in Nagaur district
  • Covers about 8.5 sq km
  • Known for saline deposits
• Sargol & Khatu
  • Associated with saline depressions
  • Typical of desert and semi-desert landscapes

These lakes lack outlets to the sea, so dissolved salts remain behind after evaporation.

🧠 Prelims Strategy Insight

UPSC often:

• Uses lesser-known inland lakes
• Tests understanding of inland drainage vs coastal features
• Rajasthan’s lakes = think saline unless stated otherwise
