The Ganges River is one of India's major river systems, with numerous tributaries contributing to its flow. To determine which river is not a tributary, we need to understand the geography of the Ganges basin.

The Ganges originates from the Gangotri Glacier and flows through northern India. Its major tributaries include:

• Yamuna - Joins at Allahabad (Prayagraj)
• Ghaghra - Joins near Chapra in Bihar
• Gandak - Joins near Patna in Bihar

However, the Satluj River is not a tributary of the Ganges. The Satluj is actually a tributary of the Indus River system, flowing through Himachal Pradesh and Punjab before joining the Chenab River in Pakistan as part of the Indus basin.

Final Answer: Satluj is not a tributary of the Ganges River.
