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

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps his Department is taking to help enhance chalk streams located in Hitchin and Harpenden constituency, including in the river (a) Hiz, (b) Oughton, (c) Purwell, (d) Mimram, (e) Lea and (f) Ver.

The Government and the Environment Agency (EA) is implementing actions identified in the Catchment Based Approach (CaBA) Chalk Streams Restoration Strategy, including improving its assessment of the flow pressure in chalk streams and working with partners to identify actions to improve flows.

Within the Hitchin and Harpenden constituency, the EA is working with the Catchment Partnership to develop river restoration projects on chalk streams near Whitwell. Further downstream on the River Mimram, it is engaging with landowners and working with Herts and Middlesex Wildlife Trust on sites at Digswell and Panshanger Park to narrow over wide and straightened channels.

On the River Lea, the EA is working with Herts and Middlesex Wildlife Trust to improve sites at Batford Springs Nature Reserve and at the Meads in Wheathampstead, stabilising banks and improving in channel and bankside vegetation.

On the River Ver, the EA is working with St Albans District Council to revitalise the water environment in Verulamium Park, restoring the River Ver to a more natural chalk stream, more resilient to climate change, and better able to support iconic chalk stream biodiversity. It has also been engaging with the Gorhambury estate to develop restoration projects.

The EA is currently in discussions with Affinity Water concerning an environmental improvement project for the River Hiz and securing funds though Ofwat’s Price Review process. In addition, since 1996, an augmentation scheme has been operational for the Rivers Hiz and Oughton to supplement flows from groundwater in times of dry weather to mitigate against the impact of abstraction.

The Government and the EA will continue to work with Water Resources East and Water Resources South East to define the long term environmental ambition for the area, including that for chalk streams.
