The original course of the River Avon was tidal throughout Bristol. The water level rose and fell as much as 30 ft (9 m) twice a day, leaving shipping stranded in the mud at low tide. A large section of the tidal river was dammed between 1804-09 to create the Floating Harbour.
- Cumberland Basin is the entrance into the Floating Harbour coming from Bristol Channel.
- Netham Lock is the entrance into the Floating Harbour coming from the inland River Avon.
- The New Cut is an artificial waterway that diverts the tidal River Avon, which runs from Totterdown Basin, near Temple Meads, to the Underfall sluices. The length of the cut is approximately 1.8 miles (2.9km).
The waterways in Bristol are operated and maintained by Bristol City Council.
