Why Students Lose Marks?
Many aspirants confuse which dam is built on which river. For example, both Nagarjunasagar and Srisailam dams are on the Krishna River, which often leads to mistakes. The trick is to remember the dam, river, and state together as a set of three.
Memory Tricks to Remember Dams
- Krishna River: Both Nagarjunasagar and Srisailam sit on the Krishna – think of them as two brothers on the same river.
- Chambal River: Three dams—Gandhi Sagar → Rana Pratap Sagar → Jawahar Sagar—remember upstream to downstream order.
- Narmada River: Two major dams—Indira Sagar (MP) and Sardar Sarovar (Gujarat)—follow the river flow.
- Tallest & Longest Dams: Tehri is the tallest, Bhakra Nangal is the highest gravity dam, Hirakud is the longest.
Practice Tip
Make flashcards with Dam – River – State sets. Revise them daily before attempting mock quizzes. Focus on upstream to downstream order for rivers with multiple dams—it helps avoid common mistakes.
