Crewgreen is monitored by 1 Environment Agency river level station on the River Severn, in Powys. Water levels are updated every 15 minutes.
Flood Zones, Warning Areas and Surface Water are Environment Agency maps and cover England only. Crewgreen 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 Hafren (River Severn), about 10 m from the middle of Crewgreen's gauges. It flows on to the sea.
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 Hafren (River Severn) nearest the middle of Crewgreen'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.
