The Broads system consists principally of tidal rivers over which there is a presumption of public right of navigation. Man-made dykes, channels and basins have been added to the main rivers and broads, and the legal status of some of these is unclear. The main rivers and cuts comprising the Norfolk & Suffolk Broads are:
River Ant - 8.3 miles (12.2 km)
River Bure - 31.3 miles (50.3 km) with a further 9 miles (14.5 km) and 5 locks derelict
River Chet - 3.5 miles (5.6 km)
Haddiscoe New Cut - 2.5 miles (4 km)
Oulton Broad and Dyke - 4.5 miles (7.2 km)
Stalham Dyke - 1.6 miles (2.4 km)
River Thurne - 5.8 miles (9.2 km)
River Waveney - 21.6 miles (34.7 km), and 1 lock, with a further 4.2 miles and 3 locks derelict
River Yare - 31.6 miles (50.8 km)
The only navigable lock is on the river Waveney, Mutford Lock in Lowestoft
The river Ant connects to the North Walsham & Dilham Canal, which is currently closed but under restoration.
The maximum size of vessels that can use the Broads is not limited by locks (other than Mutford Lock), and craft with a height of 6' 6" (2 metres) and draught of 5' (1.5 metres) can access most parts of the Broads.
