About these figures
BigQuery reports 4,665,261,859 physical rows across 72 native base tables in 8 catalogue warehouses, measured on . Structured DB measures logical bytes across the same tables. The headline excludes 4 verified staging and backup tables with 359,440 rows and 0.13 GB of logical storage. Separate publisher editions can contain overlapping observations.
The earlier 40-MCP inventory reported 1,115,017,091 records across warehouses, files and upstream sources, including 811,051,329 upstream survey records from MoSPI NADA.
Live data store measures 139.80 GB of live catalogue objects across 39 Cloud Storage buckets, measured on .
UNCTAD ingestion files account for 153.97 GB of additional live storage. Retained soft-deleted objects account for 101.90 GB. Raw publisher archives and their corresponding BigQuery tables are measured in their respective storage layers.
Data tables counts 1,02,754 publisher tables held across the marketplace MCPs, measured in each MCP's own store on 2026-11-10: one table, sheet, dataflow, report section or API dataset in one edition counts once, the way data.gov.in counts resources. Raw copies, backups and archive duplicates are not counted twice. They belong to 1,412 publications and data products — six Economic Survey reports are one publication — which hold 10,664 editions, 9,269 series and 19,717 documents. India Intelligence and Survey chapter packs are built from these MCPs and are not added. Geo-Spatial can also reach 2,36,742 data.gov.in resources live; they are not held and not counted.
The search index includes 12,121 datasets (tables, survey studies and map layers) and 367 individually indexed series. Separate live and archived access routes can have their own entries. These figures apply across the catalogue, regardless of filters.

list sources
What this MCP holds (CWC reservoirs, CGWB groundwater, CPCB water quality), coverage, units, the tools for each, and what is deliberately not served (and why).
reservoir bulletins
The CWC weekly reservoir storage bulletins available, newest first (date, file URL). start/end: 'YYYY-MM-DD' (or 'YYYY', 'YYYY-MM').
reservoir storage
Live storage from ONE CWC weekly bulletin (the latest, or the one on/before `date`). level: national | region | state | basin | reservoir. entity: name filter (substring), e.g. 'Gujarat', 'Krishna', 'Sardar Sarovar'. state / region: filters (reservoir level carries both). measures: live_storage_bcm, live_capacity_frl_bcm, live_storage_last_year_bcm, normal_storage_bcm, pct_of_live_capacity, pct_of
reservoir storage history
Weekly series across bulletins (default the last ~13 months): e.g. all-India live storage as % of capacity vs last year and normal, or one State/basin/reservoir. Reads pre-parsed bulletins; parses up to `max_new_parses` new ones per call and lists any still pending.
water quality files
CPCB NWMP years available, or one year's files by water body (rivers, medium_minor_rivers, lakes_ponds_tanks, canals, coastal_marine, drains_stps, groundwater).
water quality stations
NWMP station-wise water quality for a year: annual min/max of dissolved_oxygen_mg_l, bod_mg_l, ph, conductivity_umho_cm, nitrate_n_nitrite_n_mg_l, fecal_coliform_mpn_100ml, total_coliform_mpn_100ml, ... per station, with breaches of the bathing (Class B) criteria. query: words in the location (e.g. 'GANGA', 'YAMUNA AT'). long_rows=True returns one row per station x parameter x statistic.

water quality summary
Counts of NWMP stations by State (or India) and how many breach each bathing criterion (DO < 5, BOD > 3, faecal coliform > 2500, pH outside 6.5-8.5) at their annual extreme. Derived from the published station table.
