Source: South of Dereham, west of the village of Shipdham
Length: 83.5km (52miles)
Mouth: Great Yarmouth
Navigation: The Yare is navigable for motor boats from Norwich to the sea, canoeists can paddle from Bawburgh in the right season however the stretch between Keswick mill and Trowse can be challenging with regards barriers and numerous portages around private land.
From a ditch south west of Shipdham the Blackwater River is known as the River Yare from its first confluence with an unnamed tributary south of Runhall. Joined by the River Tiffey at Barford the Yare meanders around the south of Norwich past Bowthorpe and the UEA before being joined by the River Tas at Lakenham. Once through Trowse mills the Yare joins the River Wensum at Whitlingham and although the Wensum is the bigger river the Yare keeps its name. The Yare merges with the River Chet above Reedham before flowing into Breydon Water and flowing out to sea at Yarmouth.
Environment Agency records show that the Yare catchment is made up of nineteen waterbodies, of these eight are natural and eleven heavily modified. All nineteen waterbodies meet the Environment Agency 2016 Cycle 2 target for good chemical status. For ecological status or potential thirteen are graded moderate and six poor.
Initiatives within the catchment include the South Yare Wildlife Group and the Yare Valley Society. Research into farming and agricultural production is carried out at The Morley Agricultural Foundation near Wymondham.
