More than 15,000 homes and businesses in the north of England were hit by floods last winter, according to the latest survey.
Councils are still helping flood-hit households and businesses recover from the devastation wreaked by storms Desmond, Eva and Frank.
Claims for damage caused are expected to top £5bn, the Local Government Association says.
Staff in the eight areas affected - Cumbria, Leeds, Calderdale, Lancashire, North Yorkshire, York, Northumberland and Kirklees - have been working with volunteers and local community groups, keeping residents up to date with regular postings on their websites and through social media.
The LGA has welcomed a recent cash injection of £12.5m for temporary flood defences but says this is not enough.
It also wants funding devolved to ensure money is directed towards projects that best reflect local needs.
LGA environment spokesman Martin Tett said: ‘Government support has been vital in enabling local authorities and their communities to recover from last winter's flooding devastation.
‘The extra £12.5m announced by the Government for temporary flood defences last month is important.
‘However, councils will need significantly more support from government to help prepare for the possibility of further flooding this winter and recover from any damage.’
