Understanding the Krishna River System and its Tributaries
The question asks us to identify which river among the given options is NOT a tributary of the Krishna River. To answer this, we need to know the major rivers that join the Krishna River.
What is a Tributary River?
A tributary is a stream or river that flows into a larger river or lake. It does not flow directly into a sea or ocean.
Key Tributaries of the Krishna River
The Krishna River is one of the major peninsular rivers of India. It flows through the states of Maharashtra, Karnataka, Telangana, and Andhra Pradesh. It has several important tributaries. Some of the major left bank tributaries are the Bhima, Dindi, Peddavagu, Musi, Paleru, and Munneru. Major right bank tributaries include the Ghataprabha, Malaprabha, Tungabhadra, Vedavathi, Koyna, Venna, and Dudhaganga.
Analyzing the Options
Let's examine each given option:
- Venna River: The Venna River originates near Mahabaleshwar in Maharashtra and is a right bank tributary of the Krishna River.
- Betwa River: The Betwa River is a river in North India, a tributary of the Yamuna River. It flows through Madhya Pradesh and Uttar Pradesh. The Yamuna River itself is a tributary of the Ganges River. Therefore, the Betwa River is part of the Ganges river system, not the Krishna river system.
- Bhima River: The Bhima River is a major river in Western India and a left bank tributary of the Krishna River. It originates in the Bhimashankar hills in Maharashtra.
- Koyna River: The Koyna River is a tributary of the Krishna River that originates in the Western Ghats in Maharashtra. It is known for the Koyna Dam.
Based on this analysis, three of the given rivers (Venna, Bhima, and Koyna) are indeed tributaries of the Krishna River, while the Betwa River is a tributary of the Yamuna River.
Identifying the Non-Tributary
Comparing the information about the rivers with the options, it becomes clear that the Betwa River is the one that does not flow into the Krishna River. It belongs to a completely different river system, the Ganges-Yamuna system.
Therefore, the river that is NOT a tributary of Krishna is Betwa.

|---|---|---|

Additional Information: Major River Systems in India
India has several major river systems. Understanding these systems helps in identifying which river is a tributary of which larger river.
- Ganges River System: Includes the Ganges and its large tributaries like the Yamuna, Ghaghara, Gandak, Kosi, Chambal, Betwa, and Son.
- Brahmaputra River System: Flows through Northeast India and Bangladesh.
- Indus River System: Primarily in Pakistan, but its tributaries like the Sutlej, Beas, Ravi, Chenab, and Jhelum flow through India.
- Peninsular River Systems: Includes rivers like Krishna, Godavari, Cauvery, Mahanadi (east-flowing), and Narmada, Tapti (west-flowing).
The Krishna River is a vital part of the South Indian peninsular river system, distinct from the North Indian Ganges or Yamuna systems.
