This waterway forms the boundary between the counties of Norfolk and Suffolk for most of its length. Before the county boundary changes of 1974, it formed the boundary along its whole length, but in that year Gorleston and a few other North Suffolk parishes on the Suffolk side of the river were transferred to Norfolk. The Waveney flows into Breydon Water at Burgh Castle and there the river ends; the villages of Belton, Fritton and Blundeston were once in Suffolk and now are in Norfolk. The river Waveney flows past these villages and this is where it ceases to be the county boundary. Like the conurbation of Yarmouth and Gorleston, Thetford is another town that straddles the river, but in that case, it is the Little Ouse so we will not be considering that here.
The river Waveney rises in the Redgrave Marshes, near South Lopham in Norfolk. This is also where the source of the Little Ouse is and the two rivers rise only a matter of metres away from each other. When the glaciers of the last ice age melted a lake formed in this part of East Anglia and the Redgrave Marshes are what remains of this lake.

The river passes the towns of Diss and Harleston, both in Norfolk, before reaching Bungay and Beccles in Suffolk. In the 17th century Geldeston Lock was built between these two towns and keels (later wherries) were then able to take their commercial loads upstream to Bungay. The town flourished with the lock providing access via the river Waveney to the sea. This was supplemented by coming of the railway in 1860 and this took much of the traffic from the river. Geldeston lock closed in 1934 and since then the head of navigation has been at Geldeston Locks Inn. This remote pub gets much of its trade from its proximity to the river Waveney and its motor cruisers. Beccles has a large marina and it is the major inland port on the river Waveney. The town of Lowestoft can be accessed from the river but this requires passage through Oulton Broad.
From Breydon Water you can pass up the river Yare, but another watercourse between the two rivers is the New Cut which was constructed in 1832. Being a canal through marshland it is very straight and so quite dull but there is swing bridge where the railway crosses the New Cut at Haddiscoe. It is near where it joins the river Waveney. This was intended to be a commercial venture, allowing shipping to avoid Yarmouth where the harbour authorities imposed heavy dues. Mutford Lock was built to allow passage from Oulton Broad to Lake Lothing. The New Cut cost over £150,000 to dig. As soon as it was opened Yarmouth reduced its charges and shipping from Norwich took the more direct route to the sea. The New Cut was never a financial success and after it was damaged by the 1953 Flood it was proposed to abandon it. Luckily this did not happen. (My daughter works for the Environment Agency in Flood Control for Norfolk and it is proposed that she is given responsibility for the river Waveney. She is quite enthusiastic about the prospect – as I would be too!) The New Cut is now used far more by holidaymakers than it ever was by commercial shipping.
There is an interesting structure across the river at South Elmham St Mary between Harleston and Bungay. Homersfield Bridge was built of wrought iron, cast iron and concrete in 1869. This makes it one of the oldest concrete bridges in the world. The road bridge was in use for 101 years. It is no longer used by road traffic being replaced by a new bridge in 1970. It was restored by the Norfolk Historic Building Trust in 1990.
