Dams MCQ with answer and solution

Concept

Ukai Dam Storage Capacity

Formula

N/A

Step-by-step solution

1. Identify the key condition in the question: the reservoir with the largest storage capacity located entirely within Gujarat. 2. Note that while Sardar Sarovar is overall larger, Ukai Dam (Vallabh Sagar) is the largest entirely within Gujarat's geographical borders. 3. Select Option (a) Ukai Dam (Vallabh Sagar) as the correct answer.

Explanation

Ukai Dam, also known as Vallabh Sagar, is the largest reservoir located entirely within Gujarat's geographical boundaries. While the Sardar Sarovar Dam is larger overall, part of its catchment and submergence area extends into neighboring states. Therefore, Ukai Dam holds the distinction of having the largest gross storage capacity fully situated inside Gujarat.

Shortcut

To remember that Ukai Dam (Vallabh Sagar) is the largest reservoir entirely within Gujarat, use the rule "Ukai = Unique to Gujarat": - Sardar Sarovar: Largest overall, but shared/extends beyond state borders. - Ukai Dam: Largest gross storage capacity completely inside Gujarat's boundaries.

Common mistake

A common mistake is confusing Ukai Dam with Sardar Sarovar Dam by ignoring the crucial condition "entirely within the state's geographical borders." While Sardar Sarovar has a larger overall storage capacity, its catchment and submergence areas extend into neighboring states, whereas Ukai Dam (Vallabh Sagar) holds the largest gross storage capacity completely within Gujarat. Another frequent mistake is selecting options like Kadana Dam or Dharoi Dam due to unfamiliarity with the relative storage capacities of major reservoirs in the state.
