Asha Devi is among those who fled the floods - she paid $5 for a lift on a tractor
The BBC's Sanjoy Majumder reports from Purnea in the Indian state of Bihar where the river Kosi changed course after a dam upstream in neighbouring Nepal burst its banks in monsoon rains.
Outside the Bageecha relief camp in Purnea, Bihar, there is confusion.
A line of small trucks and vans carrying relief material have parked on the highway - scores of volunteers, dressed in white, are milling around.
They have just brought several tonnes of aid - but are not quite sure how to distribute it.
There is apparently no camp co-ordinator, no-one from the government.
It is symptomatic of what is happening across Bihar's flood-affected areas.
"We have driven several hours to get here," says Anil Chowdhury, whose cap identifies him as belonging to the Lions' Club of Khagaria.
"We've made up bundles of supplies with rice, sugar, matches and candles.
"Since the government has unable to provide for these people, we've decided to step in."
The lucky ones
Inside camp Bageecha there is more confusion.
Several hundred families have arrived here over the past five days.
The shelter they have been provided is modest - bamboo staves hammered into the ground with a plastic sheet roof to keep out the rain.
Conditions in the camp are far from ideal
There is one hand pump for all of them to use to wash themselves.
On one corner, several men are stirring large cauldrons of lentils and rice. It may not seem much, but for many here it is their first cooked meal in days.
So despite the abysmal conditions, everyone here knows they are the lucky ones who got away.
"This is how high the water reached," says Janardhan Rishidev, holding his hands waist high.
"When it started rising further, I knew it was time to leave. We packed a few things quickly, and placed the rest of our belongings on high shelves in our home.
"Then we fled. God knows if my house is still standing."
Playing in dirt
Like most people here, Janardhan waded several hours through the flood waters, holding a small bundle of his valued possessions on his head.
Asha Devi and her husband Ram were slightly luckier. Along with their children they climbed on to the back of a tractor and drove out.
At a price - they paid the driver 200 rupees ($5) for the ride.
"We hadn't eaten a proper meal in four days. My children were crying every day. At least here we've had some hot food."
There appears to be a disproportionately high number of children at this camp - most of them unclothed, playing in the dirt.
There are no medical supplies here, or any doctors. But still everyone is grateful to have got out alive.
Sitaram is 85, and managed to come here only because his sons carried him on their back.
He squats outside his tent, smoking.
"Many people were left behind," he says in a hoarse whisper, leaning forward.
"Old people whose children left them behind. I was lucky, my sons love me."
Plenty of goodwill
But there is an air of restlessness as well.
Many of the villagers are concerned that eventually somebody will ask them to leave, or the supplies will run out.
"We need to go back," says Asha Devi.
"We've lived off our land and that's the only way we'll survive. But how do we go back? When everything is under water, what will we do - swim?"
No-one has the answer to these questions, quite simply because there is no-one from the authorities here.
No government representative has been here to visit. Some international aid workers came by, but they have now left.
Outside camp Bageecha, it is complete gridlock.
Several aid trucks have blocked the road unsure of whether to pull to the side or move on ahead.
There are no policemen, so a couple of volunteers decide to sort out the chaos.
"Where's the government?" asks one volunteer angrily. "They should be here taking charge, instead they've left it to us."
There is plenty of goodwill here and quite a bit of misplaced enthusiasm.
It is just not clear whether they are all aiding the relief effort or hindering it.
