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
- the Environment Agency issues Flood Alerts and Flood Warnings that give advance notice of potential risk — sign up for these at: https://flood-warning-information.service.gov.uk/
- flooding on the island and in the Botley Road area usually occurs 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 can 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
