The widow of Cumbria flood death Pc Bill Barker and her four children are to attend a candle lit vigil to mark the first anniversary of the disaster.
The hour-long open-air tribute will take place on 20 November, near to where Pc Barker was swept to his death from Workington's Northside Bridge.
Mrs Baker, 46, said victims of gunman Derrick Bird and the Keswick school bus crash would also be remembered.
A charity auction after the vigil will raise cash for flood victims.
The event, between 1700 GMT and 1800 GMT, will conclude with the release of Chinese lanterns and a firework display.
Mrs Barker, from Egremont, said: "In just under seven months, we had three horrendous events here. For the floods to happen, is just completely unbelievable.
"But then there was the Keswick bus crash in May. And then to cap it all, only eight days later, we have the shootings.
"Of course, the effects of the floods was more than just about Bill. People lost their homes and their businesses too. We are very conscious of that and have been right from the beginning.
"The support we have had has been unstinting from the word go from people we have never known before but who I now consider friends.
"The vigil will be our way of saying thank you to them."
