HC Deb 27 April 1987 vol 115 c24W
Mr. Chris Smith

asked the Minister of Agriculture, Fisheries and Food on what occasions in the past month the Thames barrier has been raised in order to prevent flooding in the London area, other than for testing purposes.

Mr. Donald Thompson

During the past month the Thames barrier was raised on Sunday 29 March due to a combination of northerly winds, a high spring-tide, and the level of surge and fresh water flow.
