River Usk

The River Usk (Welsh: Afon Wysg) rises on the northern slopes of the Black Mountain of mid-Wales, in the easternmost part of the Brecon Beacons National Park. Initially it flows north into Usk Reservoir, then east by Sennybridge to Brecon before turning southeast to flow by Talybont-on-Usk, Crickhowell and Abergavenny after which it takes a more southerly course. Beyond the eponymous town of Usk it passes the Roman legionary fortress of Caerleon to flow through the heart of the city of Newport and into the Severn estuary at Uskmouth beyond Newport. The name of the river is usually assumed to derive from a Brythonic root word meaning "water" or "river", which in other parts of Britain has taken the form Exe, Axe, Esk and other variants....
