The Damanganga Reservoir Project, which includes about 115 kilometres of minor canals and distributaries, is located in which of the following Union Territories or regions?

Introduction / Context:
This question relates to water resource projects and Indian geography. Knowing where major reservoir projects and canal systems are located is useful for exams that cover irrigation, development schemes and regional planning.

Given Data / Assumptions:

• The project mentioned is the Damanganga Reservoir Project.
• It has about 115 kilometres of minor canals and distributaries.
• The options list several Union Territories or regions: Delhi, Dadra and Nagar Haveli, Puducherry and Goa.

Concept / Approach:
The Damanganga River flows through parts of Maharashtra, Gujarat and the Union Territory of Dadra and Nagar Haveli. The associated reservoir project and canal network have been developed to provide irrigation and water supply in this area, making Dadra and Nagar Haveli the correct location among the choices.

Step-by-Step Solution:
Step 1: Recognise that Delhi and Puducherry do not have rivers named Damanganga, so they are unlikely candidates for this project.Step 2: Goa, although a coastal state with several rivers, is not commonly associated with the Damanganga Reservoir Project in standard references.Step 3: Dadra and Nagar Haveli is a Union Territory located between Gujarat and Maharashtra, through which the Damanganga River passes.Step 4: Many irrigation and reservoir projects on the Damanganga are linked with this territory and adjoining areas.Step 5: Therefore, the Damanganga Reservoir Project with approximately 115 kilometres of minor canals is located in Dadra and Nagar Haveli.

Verification / Alternative check:
Maps showing the Damanganga River clearly connect it with Vapi region and areas near Dadra and Nagar Haveli. Government descriptions of irrigation projects in that Union Territory mention this reservoir and its canal network.

Why Other Options Are Wrong:
Option A is wrong because Delhi lies on the Yamuna River and is not associated with this project.
Option C is wrong because Puducherry is a coastal Union Territory on the southeastern side of India with its own local rivers, not the Damanganga.
Option D is wrong because although Goa has various water projects, the Damanganga system is primarily associated with the regions further north near Dadra and Nagar Haveli.

Common Pitfalls:
Candidates may guess Goa due to its coastal location or confuse the names of projects across nearby states. Carefully connecting river names with specific territories through regular map practice helps avoid such mistakes.

Final Answer:
The Damanganga Reservoir Project with its network of canals is located in Dadra and Nagar Haveli.
