Methodology · The Largest Reservoirs of Rajasthan
How this list is compiled
Measured
WHAT THIS IS. The 25 largest reservoirs in Rajasthan, ranked by the gross storage capacity their dams' owners filed on the National Register of Specified Dams 2025. GROSS, NOT LIVE, AND THE DIFFERENCE MATTERS. Gross storage is everything the reservoir holds at full supply level. Live storage is the part that can actually be drawn — the rest sits below the lowest outlet as dead storage. The register gives both; this list ranks the gross figure because it is the size of the reservoir, and the live figure is on each dam's own page. WHY THIS IS A MEASURED RANKING. The number is a filing, published by the Central Water Commission and the National Dam Safety Authority from State Dam Safety Organisation returns. Nothing here is estimated, and nothing is ours. The unit is the register's: MCM, million cubic metres. WHAT IS EXCLUDED. Dams the register records without a year of completion are under construction and are not ranked. 312 of the register's 315 Rajasthan dams were eligible. WHY ONLY 25. Stated rather than implied: the last entry holds 52.82 MCM. Below that the figures run down to fractions of a single MCM and a ranking stops telling a reader anything. ORDER. By gross storage capacity, largest first, ties broken alphabetically.
Frequently asked
- What decides the order?
- This list is ranked on a measured basis — see the methodology above for what that means for this list specifically.
- What counts as a source?
- Only a citation that is inline and expanded on the ranked subject's own page — never a source cited on this list alone.
- Why might an entry be missing?
- A rank is withdrawn, not renumbered, when the subject it named is no longer published. The gap stays visible rather than being closed.
- How often does this list change?
- A new dated edition, not a silent edit, is how the ranking itself changes.
