This flood line starts from this gauge’s measured history — the level the river only tops a few days a year. Reports of a flooded or passable day will tune it to the path itself.
Official flood warnings for Welsh paths come from Natural Resources Wales, not the Environment Agency — so check their live warnings for this area when the rivers are up.

About this path
Builth Wells' riverside park — a tree-lined avenue along the Wye carrying the Wye Valley Walk west to the Irfon confluence. The whole riverside sits inside the flood warning area and went under in Storm Dennis, the record flood here, and again in Storm Darragh in December 2024, when the riverside facilities stayed shut for cleaning.
