A Racing classic. The river Usk rises in the mountains of south Wales to the west of Brecon. It flows generally west to east past Sennybridge, Brecon, Crickhowell an Abergavenny, then turns south before Raglan to enter the Severn estuary at Newport.
The river rises and falls faster than the larger nearby river Wye, big water levels will often require paddling shortly after rain. If water levels are excessively low, it is preferable to paddle the Wye (30 mins away) as this is navigable even at very low levels.
Flood agreements are in place – whenever the river is above the line on the gauge it is ok to paddle at any time of year. Access agreements are in place for winter months. See http://webcam.wyeuskfoundation.org/navigation/index.php for details.
