The Central Water Commission weekly reservoir storage bulletin since 2019: live storage of the 128-166 monitored reservoirs, by reservoir, State, region and river basin, against last year and the ten-year normal. The Central Ground Water Board Dynamic Ground Water Resources assessments (2009 to 2025) by State/UT and district: recharge, extractable resource, extraction by use and stage of extraction, plus the CGWB publications repository (Year Books, water level reports). CPCB National Water Quality Monitoring Programme station data for rivers, lakes, canals, coastal water and drains. Every row carries its source file and sha256.
Every CWC bulletin from 2019 on: national, regional, State, basin and reservoir live storage, as a share of capacity, against the same week last year and the ten-year normal. reservoir_storage_history lays the weeks out as a series.
The National Compilation of Dynamic Ground Water Resources for each edition: recharge by season and source, extractable resource, extraction for irrigation, industry and homes, and the stage of extraction. Totals reconcile to the published India figures.
CPCB NWMP annual minimum and maximum of DO, BOD, pH, coliforms and nitrate at each monitoring location, with the bathing-water breaches flagged. CAPTCHA-gated pages are recorded, never worked around.

Weekly Reservoir Storage Bulletin: live storage of the 128-166 reservoirs CWC monitors, by reservoir, State, region, river basin and all-India, against last year and the normal (average of the previous 10 years).

tool/reservoir_bulletinsThe CWC weekly reservoir storage bulletins available, newest first (date, file URL). start/end:
'YYYY-MM-DD' (or 'YYYY', 'YYYY-MM').
tool/reservoir_storageLive 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
tool/reservoir_storage_historyWeekly 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.
tool/water_quality_filesCPCB NWMP years available, or one year's files by water body (rivers, medium_minor_rivers, lakes_ponds_tanks, canals, coastal_marine, drains_stps, groundwater).
tool/water_quality_stationsNWMP 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. The first
tool/water_quality_summaryCounts 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.
