A £4m dredging project begins at Gloucester Docks to clear severe silt build-up
Overview
A £4m dredging project has begun at Gloucester Docks after high silt levels left boats trapped and forced the docks to close this summer. While the Canal & River Trust has started clearing the sediment, local MP Alex McIntyre and other experts argue that dredging is only a short-term fix, with climate change and water pumping from the River Severn and for Bristol continuing to exacerbate the problem.
Key points
- Gloucester Docks suffered from high silt levels that reduced water depths below navigable levels, trapping boats and forcing a closure.
- The Canal & River Trust has started a £4m dredging project, using about half of its total dredging budget.
- Silt enters the docks primarily because water is pumped from the River Severn into the canal, drawing in sediment during dry weather and low river levels.
- Pumping water from the canal to supply Bristol has also been questioned as a contributing factor to the silt accumulation.
- Gloucester MP Alex McIntyre and local stakeholders believe dredging is only a temporary solution and advocate for proper filtration and stopping silt from entering the system.
- Bristol Water stated that managing silt is the responsibility of the trust, but confirmed it is working to improve operations and reduce sediment transfer.
