Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, if he will make an estimate of the expected reservoir levels for each Lower Thames reservoir for drought events (a) 1:100 years, (b) 1:200 years and (c) 1:500 years.

Public water supply reservoirs are the responsibility of the water companies. The Government has not made such estimates; however we are committed to improving water resilience and we are closely monitoring the delivery of their water resources management plans. Their plans set out how they will continue to provide secure water supplies in the long term.
