Dredging works are underway Truro this week to help restore water depth and improve access for vessels using the Port of Truro.
Part of the Truro Town Deal programme, the works at Town Quay, Garras Wharf and Worth’s Quay are scheduled to take place between August and November 2026 during suitable high tide conditions. The project will remove accumulated mud and silt from key areas of the riverbed, increasing the available navigation depth and extending the “tidal window” during which vessels can safely access the upper quays. The improvements will help support recreational boating, visiting vessels and wider activity within the port.
Extensive ecological and environmental assessments have been undertaken ahead of the dredging programme, with all necessary permissions secured, including a Marine Management Organisation licence for the approved disposal of dredged material in Falmouth Bay.
Chris Jones, Harbour Master, said: “This is a significant investment in the future of the Port of Truro. By restoring navigable depths within the upper reaches of the port, we will be able to improve access for a wider range of vessels and extend the periods during which they can safely use our quays. These improvements will enhance the experience for harbour users and support the long-term sustainability and vitality of the port.”
The dredging follows surveys carried out by Cornwall Council, the Harbour Authority for Truro, which identified areas of significant silt accumulation and helped develop a targeted programme of works to restore a smooth and consistent riverbed profile.
Following dredging, next steps involve installation of a dinghy and day boat pontoon at Garras Wharf, as well as improvements to pathways, surfacing and railings at the wharf.
Alan Stanhope, Chair of the Truro Town Deal Board, said: “Dredging the Truro river is something many people have wanted to see delivered for a long time. The river and port are central to the city’s history, identity and future, and these works will help unlock more opportunities for people to enjoy and make use of our waterfront. It is fantastic to see this work under Truro Town Deal being brought forward for the benefit of residents, businesses and visitors alike.”
Working hours will be determined by tides, weather conditions and daylight hours, and some activity may take place outside normal working hours. Notices to Mariners have been issued and measures will be in place throughout the programme to ensure safe navigation during operations.

What Will Happen?
During mid-August to the end of November, there are approximately seven tidal opportunities when conditions are suitable for the dredger to transit safely to the dredge area and turn off Town Quay.
The dredger will transit the river shortly prior to spring high water times and a Notice to Mariners has been issued. Working hours will be dependent on tide times, weather conditions and daylight hours and operations may take place outside normal working hours. During dredging operations, the appropriate navigation lights and day signals will be displayed by the dredger and the vessel will move between dredging locations as work progresses.
At times of low water, there may be a noticeable odour from disturbed estuarine mud, which is normal during dredging operations and will pass in time.
Environmental & Ecological Considerations
To ensure that the dredging will not adversely affect protected habitats, species, water quality or designated conservation sites, ecological and environmental surveys have been carried out. An MMO (Marine Management Organisation) Licence has been obtained for the disposal of dredged material in Falmouth Bay and all required permissions are in place.
