Rivers: Dredging
The question
To ask the Secretary of State for Environment, Food and Rural Affairs, how much the Environment Agency has spent on dredging rivers in each year since 2009.
Answered by Emma Hardy
The Environment Agency has no record of dredging the rivers Rother and Hipper during the last 10 years. The Environment Agency (EA) undertakes dredging to manage flood risk where it is technically effective, does not significantly increase flood risk for others downstream and is environmentally acceptable.
In most places there are much more effective and efficient ways to better protect communities and increase their resilience to flooding, as part of a catchment-based approach. Whilst dredging is part of the solution in some locations, it is not a universal solution to what is a complex issue.
Since 2009, the EA has spent the following amounts on dredging rivers.
Note that more funding was used on dredging in 2016/17 mainly due the winter floods of 2015/16 and an additional £40 million resource funding that was announced in March 2016. This allowed teams to undertake more maintenance activities, including dredging.
