Rajasthan - Rivers and Lakes

Introduction

Rajasthan's rivers and lakes are vital for its ecology, agriculture, and culture. Questions on this topic frequently appear in Rajasthan Public Service Commission (RPSC) exams, SSC CGL, and other state-level competitive exams. Understanding the major rivers, their tributaries, and important lakes helps in answering geography and environment sections effectively.

Pattern: Rajasthan - Rivers and Lakes

Pattern

This pattern tests knowledge of the major rivers flowing through Rajasthan, their origin, tributaries, and significant lakes within the state.

Key Concept:

Rajasthan's rivers mainly belong to the Indus and Ganga basins, with many being seasonal. The state also has several important lakes, both natural and artificial, crucial for water conservation in the arid region.

Important Points:

  • Luni River = Largest river of Rajasthan, flows into the Rann of Kutch, saline water.
  • Banas River = Tributary of Chambal, originates from Aravalli hills near Kumbhalgarh.
  • Saraswati River = Seasonal river, historically significant, flows through Rajasthan.
  • Chambal River = Part of the Ganga basin, flows through southeastern Rajasthan.
  • Lake Pichola = Artificial lake in Udaipur, famous tourist spot.
  • Chilika Lake = Not in Rajasthan (commonly confused with Rajasthan lakes).
