Tay 🌊 Tidal
Tay catchment • Perth • Perth and Kinross • ID: SEPA_10048 • Level
This gauge is tidally influenced — levels rise and fall with each tide, so rapid changes here are normal and don't necessarily indicate flooding.
(15m ago) • 4 readings/hr • 93 views

Get notified about Perth — tick as many as you like, they all share the notify settings below.

You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.

Each one is saved as its own alert — pause or remove them individually any time.

Not an emergency service — if in danger call 999. Alerts rely on EA/SEPA/NRW data and are best-efforts. Terms

Flood predictions aren't generated for tidal gauges — their levels are driven by the tide, not by catchment rainfall, so the forecast models would have no skill here.

💧 Storm overflows upstream of this gauge

Storm overflows whose water reaches this gauge on the mapped river network, nearest first by distance along the river. The status is each water company's monitor: it says whether an overflow is discharging, not how much or what it contains.

35 storm overflows are traced upstream of this gauge, the nearest 6.5 km away along the river. 0 report discharging now, 27 report not discharging, and for 8 the monitor is offline or has not reported, so their status is not known.

4 other overflows within 6 km are downstream of this gauge or on another branch of the river network, so they are not listed.

These are the water companies' monitor statuses; a spill does not by itself explain a change in the gauge level. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels. Explore the sewage map →

Frequently asked questions

Is the Tay at Perth flooding today?

The latest recorded level is 0.64m. Compare it with the recent history on the chart above to judge whether levels are unusually high.

Is the river level rising or falling at Perth?

Based on the most recent readings, the level is currently steady. The chart above shows the last 12 hours of measurements by default (up to 7 days), updated roughly every 15 minutes.

Why is the level slowly falling?

When little or no rain has fallen for a while, a river level gradually drops as the water stored in the ground and soil drains away with nothing to replace it. This is called baseflow recession and is normal in dry spells. Only about 8.0mm of rain has fallen nearby in the last 7 days, so the flow is being sustained mainly by groundwater. A gentle decline like this is expected and is not a sign of a problem — downstream gauges often recede a little faster than headwaters further upstream, and levels recover once rain returns.

How often is this river level data updated?

Readings are supplied by the SEPA gauge. FloodRadar checks for updates roughly every 15 minutes; the timestamp above shows how recent the latest available reading is.

Scotland — SEPA flood warnings

The Environment Agency’s flood maps cover England. In Scotland the Area map’s Flood Zones layer shows SEPA’s likelihood of flooding from rivers and the sea (darker: medium or high likelihood; lighter: low), drawn by FloodRadar from its copy of SEPA’s flood maps where it holds them. These are likelihoods, not flood zones, and an empty patch is not an absence of flood risk. Check SEPA for official Scottish flood warnings and information.
