Flooding is a recurring issue in Osney. The most serious recent events were in summer 2007 following freak rainfall, and in winters 2012 and 2014. A great deal of work has been done since 2007 to protect properties from flooding, including the installation of permanent pumps, the provision of demountable barriers which the Environment Agency can erect along the river banks, and the opening up of the channels downstream of Osney to speed the drainage of water out of the floodplain.
When flooding does occur it is useful to know that:
- it takes 4–6 days for the river level to peak following heavy rain, as water moves down the catchment area from the west
- flooding on the island and in the Botley Road area occurs very slowly and there is plenty of time to prepare
- when flooding does occur it starts with rising groundwater and it is this that has flooded some properties in the past
- the river overtopping its banks is a much later event, and the main river has not burst its banks in Osney in any recent events
- the lowest point in the island is towards the southern end and the water rises here first
- if your house is threatened in a flood event you will receive warning from the Environment Agency and you can then prepare by moving everything you can upstairs, packing bags and securing valuables
- even in recent severe flood events only a small number of properties on the island have been affected
- some vulnerable properties have been provided with small pumps to keep water below floor level
- flooding of local parks, allotments and meadows is a normal annual feature of this area and not a cause for alarm

Oxford Flood Alliance (OFA)
A community pressure group which works with local agencies, lobbies on flood-related matters, holds annual public meetings and can offer advice to local residents.
Part of OFA’s work has been to campaign for improved flood defences and a major scheme — the Oxford Flood Alleviation Scheme — is under development.
