Project summary

Edit project overview to modify the project summary.


Hoveton Great Broad is situated between the villages of Hoveton and Horning, immediately adjacent to the River Bure in the heart of the Broads. It is designated under the Habitats and Birds Directives and the RAMSCAR Convention on Wetlands of International Importance. The lake has poor plant growth and excessive sediment deposits. This acts as a source of phosphorus which causes algal growth and poor ecology. The quality of the river water has improved over recent years and is now able to support the lake restoration. None of the 21 lakes in the Broadland catchment meet good WFD status. This project will help inform future lake measures in this internationally important wetland.

Monitoring surveys and results

Edit project overview to modify the Monitoring survey and results.


Technically robust information will be available to inform the Hoveton Wetlands Restoration Project, increased understanding of the wider implications of the project on Broad fisheries status as a whole. Benefits include angler participation and support for the restoration projects. The objectives are to significantly improve the condition of the lake by creating clear water conditions in which a variety of plants and animals thrive. NE are leading on an ambitious £4.5m project funded by LIFE+ and Heritage Lottery Fund to undertake sediment removal and biomanipulation of the fish populations with the aim of resorting the lake to good status including for fish. Our aim is to support our partners in this project, add to our understanding of Broadland fisheries, and shallow lake restoration measures.

Lessons learnt

We can provide data to NE to support and inform restoration works. We will continue to work with partners to improve WFD status.
