Dams, Barrages and Power Infrastructure of Pakistan

Pakistan's dams, barrages, and power stations are a compact but high-yield topic, since the same handful of structures (Tarbela, Mangla, Sukkur, Chashma) repeat across multiple superlative questions.

Barrages:

• Sukkur Barrage is both the oldest constructed barrage and the biggest barrage of Pakistan.

Dams:

• Mangla Dam is the highest dam in Pakistan.
• Tarbela Dam has the largest water storage capacity of any dam in Pakistan, and is also the biggest hydroelectric power station of Pakistan.

Power Stations:

• Dadu hosts the biggest thermal power station in Pakistan.
• Thermal power is the largest source of energy in Pakistan (ahead of hydel, coal, and nuclear).
• Chashma Nuclear Power Plant is the biggest nuclear power station of Pakistan.

Why it matters: Tarbela and Mangla are both dams but answer different superlatives — Tarbela for largest storage capacity and biggest hydroelectric station, Mangla for highest dam — so LAT candidates must keep these two structures clearly separated in memory.
