Bihar · Opening · September 2026

The same water, one border south.

Forty-six lakh people are under flood across fifteen districts of Bihar. Part of what put them there is rain that fell on Nepal — the catchment we have spent the last fortnight working below. We are opening a response. We have no partner there yet, nothing has been bought, and nothing has moved. This page is what we know and what we need, written before we have done anything, so you can judge us later against it.

Where things stand

Forty-six lakh people, and it doubled in four days

Every number below is from the Bihar Disaster Management Department's bulletin as reported on 11 September 2026. We are publishing the state's figures rather than our own, because we have not been there and have no count of our own to offer.

The fifteen districts: Patna, Bhojpur, Saran, Vaishali, Bhagalpur, Begusarai, Buxar, Samastipur, Munger, Katihar, Lakhisarai, Khagaria, Purnea, Madhepura and Araria. Three of them — Araria, Purnea and Katihar — are a few hours' drive from our base in Siliguri. That proximity is the only reason a foundation our size has any business looking at Bihar at all.

Where the water comes from: the Nepali catchment and the flooded districts of Bihar A schematic diagram. Along the top, the Himalayan catchment in Nepal. Five rivers — the Gandak, Burhi Gandak, Bagmati, Kosi and Mahananda — run south across the India–Nepal border into Bihar, where they meet the Ganga running west to east. Fifteen districts reported as flood-affected are marked along the Ganga and in the Kosi belt: Buxar, Bhojpur, Saran, Patna, Vaishali, Samastipur, Begusarai, Lakhisarai, Munger, Khagaria, Bhagalpur, Katihar, Madhepura, Araria and Purnea. Siliguri, where Humrahi Foundation is based, is marked to the north-east, with the three nearest affected districts — Araria, Purnea and Katihar — indicated as within reach by road.

Illustration The fifteen districts sit along the Ganga mainstem and in the Kosi belt. The rivers feeding them start in Nepal, which is why the state's bulletin names rainfall there as a cause.

No death toll appears here on purpose. The state has not published one for this event, and the figures circulating online belong to earlier Bihar floods. We would rather leave a gap than fill it with a number from 2017.

Why the number keeps moving

People reported flood-affected in Bihar, 7 to 11 September 2026 A bar chart of three readings from the Bihar Disaster Management Department. On 7 September, about 27 lakh people across 13 districts. On 9 September, more than 40 lakh. On 11 September, 46.88 lakh across 15 districts. The figure roughly doubled over four days; none of the increase was a correction of an earlier number. ~27 lakh 40 lakh+ 46.88 lakh 13 districts rivers over danger 15 districts 7 SEP 2026 9 SEP 2026 11 SEP 2026 Source: Bihar Disaster Management Department bulletins, as reported. The 9 September reading is a floor — the report said “over 4 million” without a precise count.
Chart Four days, roughly double. Nothing here was a revision of an earlier number — the water kept spreading. Values: 7 Sep 2026, about 27 lakh people across 13 districts · 9 Sep 2026, more than 40 lakh · 11 Sep 2026, 46.88 lakh across 15 districts.

On 7 September the department's count was around 27 lakh people across 13 districts. On 11 September it was 46.88 lakh across 15. Nothing was corrected in between; the water simply kept spreading. Any figure you read on this page, including the ones above, is a photograph of one morning. We will restate them with a new date rather than quietly editing the old ones — the revision log at the foot records every change.

The state's own explanation names two causes: incessant rain across Bihar, and heavy downpour in Nepal's catchment areas. The rivers that drain the Nepali hills — the Kosi, the Gandak, the Bagmati, the Mahananda — do not stop at the border, and neither did this. We spent the first half of September working below that catchment on the Nepali side. This is the same weather, arriving downstream.

Before anything else

What we have actually done in Bihar so far: nothing

This is the part most appeal pages skip, so it goes first. As of today, Humrahi Foundation has not been to Bihar for this flood. No volunteer of ours has crossed into the affected districts. No relief material has been bought or moved. No organisation there has agreed to work with us. There is no Bihar field report, because there is no Bihar fieldwork.

What we have is a base a few hours from three of the affected districts, a vehicle, a collection point in Siliguri that already runs year-round, and two responses behind us this year that we published in full — Assam in August and Nepal in September. That is the whole of our credential for this.

How we work, and why it makes this page look empty. We do not arrive in a district we do not know and start distributing next to people who were already there. In Assam we went in behind the Nine Story Foundation. In Nepal we went in behind KarmaYog Foundation, who ran that operation while we contributed towards the supplies, moved them and worked the handover. Bihar needs the same thing and we have not found it yet. Until we do, the honest status of this appeal is open, funded, and waiting on a door. If you would rather give to work that is already running, our general donate page and the Nepal appeal are both live today.

Not Bihar — our own record

Since there is nothing to show you from Bihar, here is what we did in the last two

Every frame and every second of footage below is from Assam or Nepal, not from Bihar, and all of it is ours. We are showing it because an appeal opened before the work has nothing else to be judged on. It is not here to suggest we have been to Bihar. We have not.

The thing we actually need

One introduction is worth more to us than most donations

We are looking for an organisation already working in the flooded districts of Bihar — a local NGO, a relief collective, a gurudwara or temple trust running a kitchen, a panchayat-level group, anyone who is already there and can account in writing for what they distribute. Preference for Araria, Purnea, Katihar, Madhepura or Khagaria, because our vehicle can reach those and come back.

What we are offering is small and specific: money towards supplies, a vehicle out of Siliguri, and people who will work the distribution rather than photograph it. What we are not offering is a logo on somebody else's work.

  • You run or know such a group. Tell us who they are. We will do the checking.
  • You are from one of these districts. You know who is actually turning up. That is information we cannot buy.
  • You work in relief or government there. Tell us what is already covered, so we do not duplicate a kitchen that exists.

Give money

Donate to Bihar flood relief

Bihar is domestic, which changes the arithmetic entirely: there is no customs border, no crossing to wait at, and goods bought in Siliguri can be in Araria the same day a partner says yes. Money here is not paying for freight or paperwork — it is paying for the load itself. Every gift carries the reference bihar-flood-2026. Payments by Razorpay via Sevastack.

Pick an amount

This money is being raised before it has a destination. That is deliberate, and here is the safeguard.

A relief response is decided in the first fortnight and funded in the third, which is the wrong way round. We are opening this now so that the day a partner is confirmed, the first vehicle is a purchase order and not a fundraising campaign. Your amount carries over: the next screen opens with it already filled in.

Crisis Relief fundWhere these gifts sit today

Gifts to this appeal carry the bihar-flood-2026 reference inside our Crisis Relief fund. It does not yet have a separate project of its own in our donation system, so we are not going to claim it is ring-fenced when it is not — what the reference does guarantee is that every rupee tagged with it is traceable and will be accounted for as Bihar spending on our transparency page. No progress bar here: a bar on day one is a design decision pretending to be information.

300+ families reached in our Assam flood response 2 field responses published in full this year 100% of their figures and sources published

Before you give, the honest version. You would be funding a response that has not started, run by people who have not been to Bihar, through a partner who has not been found. We think that is still worth doing, because the alternative is starting the fundraise after the need peaks. But you should know exactly what you are buying. If we have not begun spending this in Bihar within sixty days of the appeal opening, we will say so on this page and contact every donor to it with the choice of a refund or of redirecting the gift to our work in Siliguri. That is the same undertaking we gave on the Nepal appeal, and we intend to be held to it here.

Rather wait and watch?

Leave an email and we will write to you once — when there is a partner and a first load, or when there is not and we are saying so. No newsletter, no second list.

Your 80G tax receipt is emailed automatically. Prefer to give to work already running? Use the general donate page.

What we have committed to

Three strands, and how far along each honestly is

The same three-column status we published for Nepal, kept for Bihar so the two can be compared. Two of these are a flat no today.

Live now

Raising money

The appeal is open and tagged bihar-flood-2026. It buys the first load the day a partner is confirmed. It is not ring-fenced in a project of its own yet and we have said so above rather than below. The sixty-day refund undertaking applies to every rupee of it.

Not yet — the blocker

Finding who to stand behind

We have no partner organisation in Bihar. This is the single thing holding the response up, and it is not a thing money fixes. Until somebody there says yes, nothing else on this page can start. If you read one section of this page, make it the one above.

Not yet — and it follows

Taking materials in

Nothing has been bought and nothing has moved. When it does, it goes by our own vehicle out of Siliguri, and the field report follows in the same shape as the Assam one: what the money bought, what it reached, and whatever did not go to plan.

The blocker is a door, not a budget. If you can open one, that is the most useful thing on this page.

Give goods

Bihar has no border in the way, so goods work here

This is the one respect in which Bihar is easier than Nepal. There is no customs post between Siliguri and Araria, so the collection we already run year-round can supply a Bihar distribution directly, without anything being couriered or cleared.

  • Sealed dry food — rice, dal, flattened rice, biscuits, anything unopened and in date.
  • Clean clothes and bedding — wearable, washed, sorted. Blankets and bedsheets especially.
  • Tarpaulin, buckets, soap, sanitary pads — the things a camp runs short of in week two, not week one.

Drop-offs go to our Siliguri collection point, which takes these the whole year round for local work and will hold them for Bihar once there is somewhere to take them. Details and hours are on the donate goods page. Please do not courier anything — call first, because a sack we cannot store is a problem we hand to somebody else.

Straight answers

Questions worth asking before you give

Have you actually been to Bihar for this flood?
No. As of today no Humrahi volunteer has been to the flood-affected districts of Bihar, nothing has been bought, nothing has moved, and no organisation there has agreed to work with us. This page is an appeal opened before the work, not a report of work done. Our two field responses this year that did happen are documented in full on our Assam and Nepal pages, and they are the only track record we are asking you to judge us on.
Then why are you asking for money now?
Because relief is decided in the first fortnight and most fundraising arrives in the third. Opening the appeal before the partner is found means the first vehicle can leave the day somebody says yes, rather than a week later. The safeguard is the undertaking we have put in writing above: if we have not begun spending this in Bihar within sixty days of the appeal opening, we will say so on this page and contact every donor to it with the choice of a refund or of redirecting the gift to our work in Siliguri.
Is this money kept separate from your general funds?
Partly, and we would rather be exact about it. Every gift to this appeal carries the reference bihar-flood-2026, so it is individually traceable and will be accounted for as Bihar spending on our transparency page. It does not yet sit in a ring-fenced project of its own in our donation system, the way the Nepal appeal does. We have said that here rather than implying a separation that does not exist yet.
Where do your figures come from?
From the Bihar Disaster Management Department's own bulletin as reported on 11 September 2026: 46.88 lakh people affected across 561 gram panchayats and 88 blocks in 15 districts, 11,255 people in 15 relief camps, 1,194 community kitchens, and the Ganga at Sultanganj in Bhagalpur standing 2.12 metres above its danger level. We publish no figure of our own for Bihar because we have none. We also publish no death toll, because the state has not released one for this event and the numbers circulating online belong to earlier Bihar floods.
Why are there no photographs on this page?
Because we have not taken any. Every photograph on our Assam page is our own, and the satellite imagery on our Nepal page is licensed and credited. Using a news-wire photograph of somebody else's flood to raise money is both a copyright problem and the thing these pages argue against, so this page carries no imagery at all until we have our own.
What is the connection to your Nepal work?
The water. The Bihar Disaster Management Department names two causes for this flood: incessant rain across Bihar, and heavy downpour in Nepal's catchment areas. The rivers draining the Nepali hills feed straight into north Bihar. We spent the first half of September working below that catchment on the Nepali side, alongside KarmaYog Foundation, who ran that operation while we contributed towards the supplies and worked the handover. Bihar is the same weather arriving downstream, and our base in Siliguri sits between the two.
Can I give goods instead of money?
Yes, and unlike Nepal it works here, because there is no customs border between Siliguri and the affected districts. Sealed dry food, clean clothes and bedding, tarpaulin, buckets, soap and sanitary pads can all go to our Siliguri collection point, which runs year-round. Please call before bringing anything rather than couriering it, so we do not end up storing what we cannot move.
Sources and methods

Where every number here came from

  1. Bihar Disaster Management Department bulletin, reported 11 September 2026 — 46.88 lakh people affected across 561 gram panchayats and 88 blocks in 15 districts; 1,194 community kitchens; 15 relief camps holding 11,255 people; 3.10 lakh polythene sheets and 48,300 dry-ration packets distributed; 1,922 boats; 27 SDRF and 10 NDRF teams; the Ganga at Sultanganj, Bhagalpur at 36.62 metres, 2.12 metres above danger level. Reported by ThePrint and Business Standard, both attributing the figures to the department.
  2. The earlier count, 7 September 2026 — approximately 27 lakh people across 13 districts, which is how we know the figure roughly doubled in four days rather than being revised. Business Standard.
  3. The cause, as the state gives it — incessant rain across Bihar coupled with heavy downpour in Nepal's catchment areas. Attributed to the department in the reporting above.
  4. Our own responses, for comparison — the Assam field report (Mautgaon, Sivasagar, 15–17 August 2026) and the Nepal appeal and field report (Trishuli and Rasuwa, from 31 August 2026). Both carry their own sources.

What we are not claiming. We have not been to Bihar, we have no partner there, we have distributed nothing, and we are publishing no beneficiary figure of our own. Nothing on this page is a Humrahi statistic. When that changes, the field report will say so with our own photographs and our own numbers, and this section will carry the revision.
