Operational matters on inland waterways are the responsibility of the relevant navigation authority, such as in this case the Environment Agency’s enforcement of illegal moorings on the non-tidal Thames.
The Environment Agency waterways department as part of Defra is aware of all mooring issues or potential reported issues on its land. The intelligence is captured and collated in the Environment Agency navigation enforcement team’s Tactical Assessment (Thames). The document includes mooring and trespass issues on Environment Agency land only and helps prioritise and deliver outcomes. Trespass and mooring issues not relating to the Environment Agency fall under riparian landowners’ or other navigation authorities’ responsibilities.
The Tactical Assessment is a classified document and deemed as sensitive and would not be shared with the public. The Thames Enforcement Plan for the Environment Agency Non-Tidal Thames, which gives an overview of enforcement actions and priorities for 2023/2024, can be viewed here: Non-Tidal River Thames Regulation and Enforcement Plan 1 April 2023 to 31 March 2024 - GOV.UK (www.gov.uk)
