The Salal Hydroelectric Project (Salal Dam) has been constructed on which of the following rivers of the Indus river system?

Introduction / Context:
Large dams and hydroelectric projects are common topics in Indian geography and general studies, especially in relation to river basins and water sharing treaties. Salal Dam, also known as the Salal Hydroelectric Project, is an important project in Jammu and Kashmir. This question tests whether the learner can correctly link Salal with the appropriate river of the Indus system.

Given Data / Assumptions:
• Four rivers are listed: Ravi, Sutlej, Ganges and Chenab. • The question asks on which river the Salal Project is built. • We assume typical exam knowledge of major hydro projects and their rivers.

Concept / Approach:
Salal Dam is a run of the river hydroelectric project located in the Reasi district of Jammu and Kashmir. It is built on the Chenab River, one of the main western rivers of the Indus system that flows through the Jammu region before entering Pakistan. Remembering this association helps in questions related to both geography and current affairs.

Step-by-Step Solution:
Step 1: Recall that Salal is in the Jammu region and is linked with western Himalayan rivers. Step 2: Remember that the Chenab River flows through this area, while the Ravi and Sutlej follow slightly different routes. Step 3: Confirm from standard dam lists that Salal Hydroelectric Project is constructed on the Chenab River.

Verification / Alternative check:
Lists of major Indian hydel projects consistently describe Salal as a 690 megawatt run of the river project on the Chenab in Reasi district. No reliable reference associates the Salal Project with the Ravi, Sutlej or Ganga.

Why Other Options Are Wrong:
Option A (Ravi) has other projects such as Ranjit Sagar Dam, but not Salal. Option B (Sutlej) is famous for projects like Bhakra Nangal, but Salal is not one of them. Option C (Ganges) is the main river of the Indo Gangetic plain and has several barrages and projects, but Salal is located in the Chenab basin of the Indus system.

Common Pitfalls:
• Learners sometimes confuse Salal with Bhakra or other major north Indian dams and incorrectly link it to the Sutlej. • Another mistake is to mark the Ganga whenever any famous dam is mentioned, without recalling the specific basin details.

Final Answer:
The Salal Hydroelectric Project is built on the Chenab River.
