Llanymynech is a village and former civil parish straddling the border between Powys, Wales, and Shropshire, England, about 9 miles (14 km) north of the Welsh town of Welshpool. The name is Welsh for "Llan of the Monks". The village is on the banks of the River Vyrnwy, and the Montgomery Canal passes through it.
Flood Zones, Warning Areas and Surface Water are Environment Agency maps and cover England only. Llanymynech is in Wales, so they draw little or nothing here — that is where the map ends, not an absence of flood risk. Natural Resources Wales’s warning areas have their own pages under flood areas.
The nearest watercourse on the river map is Afon Efyrnwy (River Vyrnwy), about 20 m from the middle of Llanymynech's gauges. It flows into Afon Hafren (River Severn) about 18 km downstream.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on Afon Efyrnwy (River Vyrnwy) nearest the middle of Llanymynech's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
Llanymynech is monitored by 1 Natural Resources Wales river level station on the Vyrnwy, in Powys. Water levels are updated every 15 minutes, providing real-time flood monitoring for the area.
The Vyrnwy is monitored by 1 station (Llanymynech River Station). Each station records water levels continuously, with data synced to FloodRadar every 5 minutes.
