Explanation:

Statement 1: The Full Reservoir Level (FRL) of Polavaram is 45.72 metres. Correct

• At this height, the dam stores 194.6 TMC of water.

Statement 2: The Left Main Canal covers a larger area than the Right Main Canal. Correct

• Left Main Canal (LMC) → Covers 4 lakh acres (East Godavari + Visakhapatnam)
• Right Main Canal (RMC) → Covers 3.2 lakh acres (West Godavari + Krishna)

Since 4 lakh acres > 3.2 lakh acres, LMC covers a larger area.

Statement 3: The Diaphragm Wall works are scheduled for completion in 2027. Incorrect

• Diaphragm Wall works are targeted to be completed by February 2026.
• 2027 is the early completion deadline for ECRF Gap-II, NOT the D-wall.

Statement 4: The project aims to stabilise more than 10 lakh acres of existing command area. Correct

• The project will stabilise 13.5 lakh acres under:
  • Sir Arthur Cotton Barrage
  • Prakasam Barrage

13.5 lakh > 10 lakh, so the statement is correct.

Therefore, Statement 4 is correct.
