Craig-y-nos is monitored by 1 Natural Resources Wales river level station on the Tawe, in Powys. Water levels are updated every 15 minutes.
Flood Zones, Warning Areas and Surface Water are Environment Agency maps and cover England only. Craig-y-nos 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 Tawe (River Tawe), about 60 m from the middle of Craig-y-nos'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 Tawe (River Tawe) nearest the middle of Craig-y-nos'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.
Craig-y-nos is monitored by 1 Natural Resources Wales river level station on the Tawe, in Powys. Water levels are updated every 15 minutes, providing real-time flood monitoring for the area.
The Tawe is monitored by 1 station (Craig Y Nos River Station). Each station records water levels continuously, with data synced to FloodRadar every 5 minutes.
No Environment Agency flood warning area is mapped within 10km of Craig-y-nos. That means the EA has not defined a warning target area here, which is not evidence the town cannot flood: warning areas exist where the EA runs a warning service, and surface-water and groundwater flooding have no warning areas at all. The EA’s register covers England only — Craig-y-nos is in Wales, where the warning service is Natural Resources Wales’s, and FloodRadar publishes its areas alongside the EA’s on the flood areas index.
There are 6 storm overflows within 5km of Craig-y-nos. None of the 6 with a reporting monitor are currently discharging. Enable "Sewage" on the map above to see their locations.
Each has its own page of live status and past discharges:

No recorded flood outline within ~5 km of the Craig-y-nos town centre means no flood was mapped here, which is not evidence none happened: the Environment Agency mapped only some floods, mapping effort rose sharply after about 2000, and surface-water flooding is largely absent from this record. The Environment Agency's Recorded Flood Outlines cover England only, and Craig-y-nos is in Wales — so an empty record here is an absence of coverage, not an absence of floods.
