What we track for Nagpur
Nagpur is governed by Nagpur Municipal Corporation, Water Works Department with civic services under Nagpur Municipal Corporation (38 wards).
Water sources
Reading this dashboard
Why Nagpur's dashboard has no days-of-water figure
The scenarios above apply to a city that stores its own water. Nagpur's two reservoirs are a hydro-electric dam shared with Madhya Pradesh and an irrigation dam, in which NMC holds a yearly reservation, and its Kanhan plant draws from the river itself. A countdown would treat the whole of that water as the city's, so the dashboard leads with the supply chain and the reservoir cards instead, and the allocation ledger sets the city's share beside what it is recorded as drawing.
What each page shows for Nagpur
What we track, and how often it changes
Some of Nagpur's layers are read every day; most come from documents published once a year or less. Each page dates what it shows. In order of how often they change:
- Every morning: storage in Totladoh and Navegaon Khairi, the two Pench dams, from the state Water Resources Department's dam bulletin. The record starts at the earliest dated bulletin this site holds, and each day's bulletin also gives the same date a year earlier. The department keeps dated copies of the bulletin from the end of February 2024.
- Every day, provisionally: rainfall for the months the India Meteorological Department (IMD) has not yet published in its gridded record, replaced by IMD's figures when they come out. IMD's record on this site runs to December 2025.
- Monthly averages, refreshed by hand: water levels in 101 groundwater telemetry wells on the National Water Data Portal. The latest month is September 2026 for most of the district and June 2026 for the three wells inside the city.
- Once a year: NMC's Environment Status Report (latest: 2023-24, published August 2025) and budget (2026-27, May 2026); the national groundwater assessment (2025-2026 edition); MPCB's monthly river readings, released as yearly files (to December 2024).
- Dated snapshots: the State's water-body survey (2017-18), the 2025 ward map, NMC's river sampling (monsoon 2023), the State's flood-line register and the commitments register (both read on 15 October 2026), and the order and resolution behind the city's Pench share (2018 and 2020).
Dashboard - Pench water from a shared reservoir, and the Kanhan
Four of Nagpur's five treatment plants run on Pench water. NMC's Environment Status Report 2023-24 (prepared by CSIR-NEERI, section 6.2.1, printed pp.132-133) lists five plants with 786 MLD of capacity: Pench I to IV (136, 175, 120 and 115 MLD, 546 in all) and Kanhan (240 MLD). The Pench water is released from Totladoh, the Pench hydro-electric reservoir shared with Madhya Pradesh, into the Navegaon Khairi pick-up dam, and goes to the Mahadula pumping station, at km 48.5 of the old canal route (ESR 2017-18 draft). NMC told the state regulator that a closed pipeline replaced the canal in April 2015. The Kanhan plant lifts water from the river 14 km from the city.
The dashboard opens on that supply chain. Its structure figures are NMC's most recent: its 2026-27 budget (published May 2026) counts 4.50 lakh water connections, 106 water tanks, 4,650 km of distribution mains and 37 tankers for areas the network does not reach. The water balance below it is dated: for 2023-24, the report records 706 MLD supplied, 410 MLD billed and 41.91% lost between source and consumer, and counts ‘certain areas’ in 36 of its 73 command areas as dark zones, where supply was found to be under two hours a day.
What NMC does not publish, that we have found
Supply by source. NMC's reports give treatment capacity plant by plant and one citywide total of water supplied, so the source split on the dashboard is capacity, not supply. The latest figures by source are the raw-water bills in NMC's draft 2017-18 report, whose table gives no year.
Hours of supply across the city. The reports count the command areas with dark zones but give no citywide hours.
A current population. The last census count is from 2011, and the report's own estimate cites a commercial website, so the dashboard divides nothing by population.
Figures shown exactly as NMC printed them
The 2023-24 report prints a loss of 41.91%; 410 of 706 gives 41.93%. The 2022-23 report states 47%, while its own table (250.679 million cubic metres supplied, 377.454 MLD billed) gives 45.0% on our arithmetic, and that table's monthly rows add to 250.672 million cubic metres against a printed total of 250.679. NMC dates its baseline of 346 tankers to 2016 in the environment reports and to 2018 in the budgets. The 2026-27 budget reports water revenue received ‘to January 2027’ in a speech that prints no date (the budget was published in May 2026, and the latest date inside the speech is late February 2026), which we read as January 2026. Each figure is shown as printed, not corrected to make the sums agree.
Reservoirs - and why there is no days-of-water-left number
The dashboard carries Totladoh and Navegaon Khairi (Kamthi Khairy in the state's bulletin). Neither is the city's own storage. The Central Water Commission's National Register of Large Dams (2019) lists Totladoh as a hydro-electric dam and Kamthikhairy as an irrigation dam; NMC holds a yearly reservation in the water they release. Each card shows the whole dam's live storage against its designed live capacity (1,016.93 and 141.98 million cubic metres), as the bulletin reports it, never a city share. Dividing them by the city's demand would credit Nagpur with water planned for irrigation, power and Madhya Pradesh, so no days-left figure is computed.
The Kanhan intake and Gorewada lake are listed without a reading. The intake draws from the running river, 300 m below the confluence of the Kolar and the Kanhan, so there is no stored volume to show. Gorewada was built in 1911 on the Pili as a source for the city and is not in the state's daily bulletin. Khindsi, Nand and Wadgaon, irrigation dams in the same district block of the bulletin, are read but not shown as city sources.
What the history chart does not use
The National Water Data Portal also carries the Central Water Commission's daily level at Totladoh from June 2019, under a non-commercial licence, so it is not used here. Each day's bulletin prints the same date a year earlier only as a percentage; the chart turns it into a volume using the designed capacity. None of the sources used gives a full reservoir level for Kamthi Khairy, so none is shown.
Allocations - a reservation inside a power and irrigation project
The allocation ledger sets NMC's Pench share beside what the city is recorded as drawing. The share grew in steps: 112 million cubic metres a year in the project plan (by NMC's account, a State letter of 29 March 1965), 78 more sanctioned in 1998 as a temporary measure, made permanent in 2008 on conditions the regulator records as not yet met, and in 2010 continued as a temporary reservation until further orders; and set at 190 in the Water Resources Department's resolution of 19 March 2020 (in Marathi, table on p.2), rising to 341 in a second phase that includes a planned 62 km tunnel bringing 10 TMC from the Kanhan in Madhya Pradesh. The state water regulator's order of 12 September 2018 holds the 78 ‘legal and intact as on today’.
The most recent published figures for what the city draws from each source are in NMC's draft 2017-18 report (its table is headed ‘present’ and gives no year): 143.0 million cubic metres billed for the Pench, 43.8 for the Kanhan and 6.8 for Gorewada. The same report says the four Pench plants treated 456 MLD that year (about 166 million cubic metres) and the Kanhan plant 185 MLD (about 67.5), more than either bill, and lists the Gorewada plant at 16 MLD of capacity and output, below its 20 MLD bill. Because the billed and treated figures disagree for all three, the ledger shows no delivery figure for any of them and gives both in each row's note. The regulator's order records that the 2017 monsoon was lean. Volumes stay in the unit of the orders; 1 million cubic metres a year is about 2.74 million litres a day.
Where the record is thin
The 2017-18 draws come from NMC's draft Environment Status Report for that year, which we have read only in a copy hosted outside NMC's website. The Kanhan has four figures from four documents (55.00, 58 and 60 million cubic metres a year, and 65.71 in a 2023 resolution that states no period) and no reservation order we have found. The 2020 re-planning is subject to a joint committee's decision on the project's yield, which we have not found published.
Groundwater - Safe across the district, read by category
The groundwater map shows Nagpur district's 14 talukas across six editions of the national groundwater assessment (IN-GRES, 2019-2020 to 2025-2026), drawn on IN-GRES's own unit boundaries. The measure is the stage of extraction: how much of the groundwater that can be drawn each year (what refills, less what flows away naturally) is pumped out. The district reads Safe in all six editions, its stage falling from 51.87% to 45.30%, and every taluka reads Safe on its total in 2025-2026 (Hingna's canal command area reads Semi Critical); Saoner is highest at 67.53%, below the 70% line where CGWB's Semi Critical class begins.
The city's own unit: the category is the steadier comparison
In IN-GRES's 2023-2024 area figures the city first appears as its own unit, Nagpur (Urban), with 22,457 ha, and three units' assessed areas fall by the same total: Nagpur (Rural) by 6,277 ha, Kamptee by 16,081 ha and Hingna by 99 ha. It is Safe in all three of its editions. The 2025-2026 row enters 206 ha of the unit as canal command area (16,081 ha the year before); its other figures repeat the 2024-2025 values, so its stage of 54.62% is in effect that of the non-command part alone, and the rise from 33.10% comes from that change. The taluka panel shows the unit's three editions as bars (31.30%, 33.10% and 54.62%) with this caveat beside them. The older unit named NAGPUR is carried on as Nagpur (Rural), whose assessed area fell by those 6,277 ha.
The dots are 101 telemetry wells, 91 run by the state's Groundwater Surveys and Development Agency and 10 by the Central Ground Water Board, read every six hours on the National Water Data Portal and shown as monthly means. Three stand inside the city, all of them the board's piezometers; their readings stop in June 2026, while 59 wells elsewhere in the district report into September 2026.
Why there is no ward-by-ward depth map
The three wells in the city read a deeper, semi-confined aquifer than the shallow dug wells with long records, so a depth surface drawn across the wards would average two aquifers into one number. The page shows the wells themselves instead. The state agency's manual dug-well record is not on the map.
Rivers - NMC samples the city's three, MPCB the river they drain to
The rivers page carries six rivers. The Nag, the Pili and the Pora run through the city: NMC sampled them in the monsoon of 2023 at 23 points (10 on the Nag, 8 on the Pili, 5 on the Pora), and the readings are its Environment Status Report's. On the Nag, dissolved oxygen falls from 3.67 mg/L where it leaves Ambazari lake to 0.48 mg/L at its last point in the city, and MPCB's water quality index for 2023-24 puts it at 75 near Ambazari lake and 36 at Bhandewadi bridge. The three city rivers have no CPCB readings: MPCB lists five national-programme stations on the Nag and the Pili (codes 5979 to 5983), but CPCB's river tables up to 2024 carry none of them, and neither list has a station on the Pora.
Around the city, MPCB samples the Kanhan, the Kolar and the Wainganga every month at five national-programme stations: 480 monthly readings from January 2017 to December 2024, with the 17 months it recorded as dry and the 3 as stagnant water kept as such. The highest BOD at Agargaon, downstream of the city, was 9.8 mg/L in 2023 and 7.4 in 2024, against 3.5 upstream at Sinora; the river there was dry every June from 2019 to 2024. For 2021 to 2024 MPCB's monthly figures reproduce CPCB's yearly lowest and highest values. CPCB's 2025 polluted-stretch report puts all three rivers in Priority IV.
Shown with care
NMC counts faecal bacteria in CFU per 100 ml, not the MPN unit of MPCB's readings; the panel labels each NMC reading in CFU. The station at Ambhora on the Wainganga is shown without a marker, because CPCB's list places it about 145 km south of the village and MPCB's about 53 km north-west.
What is not measured in public, or not shown
We have not found a live water-quality station on any of the six rivers, so the page shows months and years, not days. The treatment-plant panel other cities carry is off: NMC's report lists 13 sewage plants, 12 of them working with 403.5 MLD of capacity against an estimated 520 MLD of sewage (73% of supply), but we have not found monthly outlet readings for each plant.
Flood risk - rain on three city rivers
Nagpur's flood record is rain on the Nag, the Pili and the Pora, the rivers that carry the city's storm water. In the 24 hours to the morning of 23 September 2023 the state's rain gauges recorded 166 mm at the Nagpur City circle (the Sitabardi circle carries the same daily figure); the district plan says the heavy rain fell between midnight and dawn. The Bombay High Court's order of 11 July 2024 records the Collector's affidavit that four people died, and the district disaster plan records 349 people rescued. In November 2020 Nagpur's Water Works Department had recorded that Ambazari's spillway was designed to pass 400 cubic metres a second but the road bridge below it 60. The heaviest day on IMD's record for its Nagpur observatory is 315.0 mm, on 12 June 1911.
The page is a dated record, not a hazard map. The state's red and blue flood-line sheets exist for the Nag only over 3.55 km at the city's eastern edge, and for 5.3 km of the Pora, as scanned sheets; they are linked, not drawn. NMC's 2025-26 disaster plan names 77 places where water collects in heavy rain, but without locations.
What is not public yet, that we have found
Flood lines for the Pili and for the Nag through the city centre; a map of the storm drains (the City Development Plan of 2015 records about 917 km, surveyed in 2008); the rainfall the drains are built for; a water-level gauge on the city's rivers; and IMD's own reading for 23 September 2023.
Water bodies - from the State's 2017-18 survey
The water-bodies map draws 1,767 water bodies from the Maharashtra Remote Sensing Applications Centre's (MRSAC) survey at 1:10,000, mapped in 2017-18: farm ponds, tanks, lakes, quarries, aquaculture ponds and reservoirs, out to the Pench reservoirs north of the city. 29 of them lie inside the city's wards. 56 are named in the survey; 9 more take their name from OpenStreetMap where an OpenStreetMap lake overlaps them. The survey's area field holds square kilometres under a hectare label, so areas are converted.
Dated, and official first
The survey describes 2017-18: ponds dug since are not in it, and ponds filled since are shown as they were then. 111 OpenStreetMap water polygons in the same area match nothing in the survey; they are left off rather than mixed in. NMC counts 11 lakes but publishes no register of their areas that we have found.
Lake restoration - sanctions, reports and a court docket
The lake-restoration page sets eight of the city's lakes (Futala, Ambazari, Gorewada, Gandhisagar, Sonegaon, Sakkardara, Naik and Lendi) beside the work on them and 10 court and tribunal orders. History comes from the Imperial Gazetteer (1908), the 1966 District Gazetteer and the Supreme Court's 2025 judgment on Futala, which records it as also known as Telangkhedi tank; dam figures from the Central Water Commission's register; current work from NMC's reports and budgets, the State's resolutions and the AMRUT 2.0 portal.
Where two documents disagree on the same lake, both are shown: Naik lake was sanctioned at Rs 12.95 crore in 2022 and is listed at Rs 15.95 crore on the portal.
No register of lost lakes
We have not found a public register of the lakes Nagpur has lost, so the page carries the lakes that exist and the work on them, not a count of those that are gone.
My Ward - 38 wards on the 2025 map
My Ward covers the 38 wards of the final ward notification of 4 October 2025 (37 with four councillors, one with three, 151 in all). The outlines are MRSAC's ward map; the populations are the ones the notification prints, 2,447,494 across the city, and it does not name the census year they come from. A ward is shown with an NMC zone only where one zone holds at least 90% of its area (20 of the 38 wards); the other 18 cross zone lines and show none.
Four ward edges to confirm
MRSAC's ward populations follow the August 2025 draft, with some typing slips and a different 23/26 split. The final notification moved part of the lines between wards 6 and 7, 7 and 9, and 8 and 19, and MRSAC's line between wards 23 and 26 differs from both the draft and the final, so those edges may not follow the final line. The legal map is kept at the NMC office.
Each ward shows what can honestly be placed in it: its groundwater unit (37 wards sit in Nagpur (Urban), one in Nagpur (Rural)), the nearest telemetry well within 5 km (15 wards have one), the nearest river sampling point (for every ward, one of NMC's 2023 points), and the water bodies inside it (29 across the city).
Five sections read 'not available', each for a stated reason
- Lost lakes: no public register of the city's lost lakes has been found.
- Flooding: NMC's disaster plan names the places where water collects, without locations.
- Drainage: we have not found the storm-drain network published as a map.
- Sewerage: NMC locates its sewage plants, but we have not found a map of the sewer network.
- Industry: MPCB's river plans name the power stations and industries along the Kanhan and the Kolar, without locations.
Commitments - each promise on its own document
The commitments page tracks 22 promises about Nagpur's water, each on a dated Government Resolution, a court or tribunal order, an NMC budget or report, the AMRUT 2.0 portal or a funder's document. 4 are delivered and 1 is on track. One has a date moved by NMC that has not yet come; three are past their date with no delivery on record, one of them after NMC moved it. 1 is recorded as stalled. For 12 the promise can be cited but not yet its current status. A status changes only against a dated document, and each row not yet delivered carries the date it is next checked.
Five of the resolutions did not open at the State's resolutions portal on 15 October 2026. Their text was read from the orgpedia archive copy, and each of those rows links the copy beside the official address.
Facts and rainfall
The facts page is a set of 22 cards, each read from the data behind the page it summarises rather than typed in a second time. One is a gap: the supply from each source, which we have not found published after NMC's draft 2017-18 report.
Rainfall comes from IMD's 0.25-degree gridded record, 1970 to 2025, at the grid cell at 21.0 N, 79.0 E, the one nearest IMD's Nagpur observatory. We checked the choice: the observatory's normal is 1,151.2 mm a year (1991-2020), and this cell gives 1,148.8 mm over the same years. Its 1970-2020 average is 1,126.4 mm. Months after IMD's last published month are filled from Open-Meteo's reanalysis and marked provisional until IMD catches up.
Origins - a small stream, and a river from Madhya Pradesh
The origins page tells the city's water history in six chapters: the small stream called the Nag; the Bhonsle tanks, from a British officer's plan of 1819; the gravity waterworks of 1873 and the drains that followed; Gorewada in 1911 and then the Kanhan; the Pench, shared with Madhya Pradesh, from 1982; and what the old tanks became. Its sources are the Imperial Gazetteer (1908), the District Gazetteers of 1966 and 1979, the Central Water Commission's dam register, NMC's reports and the state water regulator's order. Where those sources give different dates for the same event, the page says so.
What is not here, and why
Each absence below is a decision, and each has a stated reason.
No tanker page
NMC publishes how many tankers it runs (37 in its 2026-27 budget, published May 2026), but we have not found a delivery register, booking ledger or price survey, which a tanker page would need.
No shoreline or climate-risk page
Nagpur is near the centre of the country and has no coastline. A climate-risk page is possible and planned: the global basin data it rests on covers the Kanhan and the Wainganga.
English only, for now
The pages are in English; Marathi is planned.
Intelligence & AI narratives
Nagpur's pages show the published figures directly, each with its source and date; there is no automated written summary for the city.
Data sources for Nagpur
All operational data is collected by the Python pipeline and supporting scripts that power the dashboard. Raw source data and Earth Engine summaries are upserted into Supabase (PostgreSQL) and then exposed as small, readable product signals.
Supply, reservoirs and the Pench share
The corporation's latest published account of its water: five treatment plants and their capacities, water supplied and billed, the loss from source to consumer, the 73 command areas and the dark zones within them, and tap-water sampling (2023-24, section 6.2.1, printed pp.132-134). The 2022-23 edition gives the year before.
Water connections, water tanks, distribution mains and the tanker count (2026-27, pp.B-3 to B-4), and the money for the lake and river projects. The 2026-27 budget is a scanned Marathi document, read on its page images.
The only report we have found with the city's draw source by source (Tables 4.3 and 4.4, p.23), and the history of the Kanhan intake and barrage. No NMC-hosted copy has been found, so the allocation ledger says where each 2017-18 figure comes from.

The re-planning of 19 March 2020 that sets NMC's share at 190 million cubic metres a year, and 341 in a second phase; the Lohghogari tunnel approval of 18 September 2019; the Kolar-Kanhan barrage study of 18 April 2023, read from the orgpedia archive copy because the official address did not open on 15 October 2026. In Marathi.
The state's all-Maharashtra bulletin, every morning. The cards read Totladoh and Kamthi Khairy (Navegaon Khairi) inside the bulletin's Nagpur district block, by whole name, as live storage against designed live capacity. The bulletin's same-date-last-year column extends the history backwards, and the department keeps dated Marathi copies from the end of February 2024.

Rainfall
Grid cell 21.0 N, 79.0 E, 1970 to 2025, the cell nearest IMD's Nagpur observatory. Checked against the observatory's normal of 1,151.2 mm (1991-2020): the cell gives 1,148.8 mm over the same years.
Provisional daily rainfall at the same point for the months after IMD's last published month (CC BY 4.0), marked provisional and replaced when IMD catches up.
The observatory's normals and records: 1,151.2 mm a year, 347.7 mm of it in July; 315.0 mm on 12 June 1911 and 304.0 mm on 12 July 1994.
Daily rainfall at the Nagpur City circle from 1997, and at Sitabardi and Pardi from 2013, with each month's normal: the rainfall behind each flood event on the flood page.
Groundwater
The national Dynamic Ground Water Resource Assessment for the district's 14 talukas, six editions from 2019-2020 to 2025-2026, drawn on IN-GRES's own unit polygons. The district's 2024-2025 figures are checked against CGWB's printed national compilation.
Six-hourly readings from 101 wells in the district, 91 run by the state's Groundwater Surveys and Development Agency and 10 by CGWB, shown as monthly means after quality checks. Wells are placed by their coordinates.
The printed district figures (Nagpur 45.68%, Safe, 2024-2025) the IN-GRES build is checked against.
Water bodies and restoration
Every water body on the map, 1,767 in the frame around the city, with its type, from the Maharashtra Remote Sensing Applications Centre's PM Gati Shakti server. Its area field holds square kilometres and is converted. The service states no licence; it is cited as a state publication.
Names for water bodies the survey leaves unnamed, joined where the two outlines overlap, and the locality names in the ward search (ODbL 1.0).

Rivers and pollution
Monthly pH, dissolved oxygen, BOD and bacteria at five national-programme stations, January 2017 to December 2024, with dry and stagnant months as MPCB records them. For 2021 to 2024 they reproduce CPCB's yearly lowest and highest values.
23 sampling points on the Nag, the Pili and the Pora in the monsoon of 2023 (Tables 6.13 to 6.16, printed pp.161-166), and the 13 sewage treatment plants with their capacity and status (Table 6.3, p.137).

Station positions and the yearly lowest and highest values used to check MPCB's monthly figures. One station's position (Ambhora, 1910) is withheld because both official lists place it far from the village.
The priority class of the Kanhan, the Kolar and the Wainganga in each edition. CPCB's website policy requires its approval for any use beyond download and print, so the report is cited here, not copied.
Flood and civic infrastructure
The state's register of red and blue flood-line maps: 13 register entries for five rivers and a nalla around the city (the Nag, the Pora, the Kanhan, the Kolar, the Vena and the Bagdor nalla), including four for the Nag (3.55 km at Pardi, Punapur and Bharatwada) and one for the Pora. The register also lists Nagpur-district entries for the Wainganga, the Jam and the Nand, not listed here. Scanned maps, linked rather than drawn.

Wards and boundaries
NMC's own outline of the city and its ten zones. A ward is shown with a zone only where one zone holds at least 90% of it (20 of the 38 wards); the others cross zone lines and show none. A searched place shows the zone at its own point.
The outlines of the 38 wards from MRSAC's map, whose population figures follow the August 2025 draft; the edges between wards 6 and 7, 7 and 9, 8 and 19, and 23 and 26 may differ from the final notification.
The 38 wards, their councillors and the population printed for each ward (English schedule, pp.35-68), with the State Election Commission's approval.
The six rivers on the maps: the Nag, the Pili, the Pora, the Kanhan, the Kolar and the Wainganga.
Data quality & limitations
How we classify river health
CPCB publishes two parallel river-water-quality classification systems, and they don't always agree. Knowing which one we use - and why - matters for reading our river status badges honestly.
Designated Best-Use classes (A-E)
Computed from current dissolved-oxygen, BOD and coliform thresholds at each monitoring station. Updates every reading. Class A = drinking with disinfection only; Class B = outdoor bathing; Class C = drinking with conventional treatment; Class D = fisheries/wildlife; Class E = irrigation only. Below E = practically dead.
Polluted River Stretch (PRS) Priority I-V
A historical, multi-year stretch-level designation reflecting cumulative pollution. Slow to update; once a river stretch is on the Priority list it tends to stay there even if recent readings improve. Priority I = worst (BOD > 30 mg/L sustained); Priority V = least bad of the polluted stretches.
Our status badges ("dead", "severely degraded", "degraded", "stressed", "healthy") are computed from current readings via the Designated Best-Use thresholds - not from the PRS Priority list. We take the worst classification across a river's monitored stations and surface that as the river-level status.
For Nagpur, the readings behind the badges are MPCB's monthly figures for the Kanhan, the Kolar and the Wainganga, and NMC's 2023 sampling for the Nag, the Pili and the Pora, not CPCB's annual reports. The three city rivers have no CPCB readings: MPCB lists five national-programme stations on the Nag and the Pili (codes 5979 to 5983), but CPCB's river tables up to 2024 carry none of them, and neither list has a station on the Pora. Their badges come from NMC's points, where dissolved oxygen fell below 1 mg/L on all three. The Kanhan, the Kolar and the Wainganga are Priority IV in CPCB's 2025 list, but their badges follow MPCB's latest readings.
Status thresholds follow CPCB's published Designated Best-Use criteria; the readings are MPCB's monthly figures and NMC's 2023 sampling, as above.
Where Nagpur's figures need care
- Eight documents were read from copies or scans: the 2017-18 draft Environment Status Report (a copy hosted outside NMC's website), five Government Resolutions (the orgpedia archive copy), NMC's 2026-27 budget and the regulator's 2018 order (scans, read on their page images). Each row that rests on one says so.
- Reservoir percentages are of designed live storage, the state bulletin's basis, and describe the whole dam, not the city's share.
- The 2025-2026 groundwater figure for Nagpur (Urban) enters 206 ha of the unit as canal command area (16,081 ha the year before), so its stage is in effect that of the non-command part alone; its category, Safe in all three editions, is the steadier comparison.
- Four ward edges (between wards 6 and 7, 7 and 9, 8 and 19, and 23 and 26) may follow an earlier line than the final one.
- The water-body survey and the ward populations are dated: the survey is of 2017-18, and the ward notification does not name its census year.
Known Limitations
- Only the storage in the two Pench dams is read every day. Everything else comes from documents published once a year or less, so a figure on these pages can be more than a year old; each one carries its date.
- The state's dam bulletin is published every morning but can be late or skipped, for example on holidays.
- The groundwater assessment describes whole talukas, with the city as one unit; it does not measure individual wards or streets. The well readings are monthly means of six-hourly telemetry after quality checks.
- Inside the city the river readings are one sampling round by NMC in the 2023 monsoon, with no BOD column; below the city, MPCB's monthly readings run to December 2024. Neither is a live reading.
- Rainfall after December 2025 is provisional: reanalysis estimates (Open-Meteo) for one grid point, replaced when IMD publishes its gridded figures.
- The flood page is a record of past events, not a forecast and not a hazard map.
