Quick pick:
You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.
You'll be notified when a new storm-overflow (sewage) discharge starts within ~3 km of this gauge, based on the water companies' near-real-time feeds.

River Flow
90 days
Daily mean discharge (m³/s) with the daily min–max band, from the EA Hydrology API. Flow is the volume of water passing the gauge — often a more direct flood signal than level.

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.
3 storm overflows are traced upstream of this gauge. 0 report discharging now, 3 report not discharging.

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 →
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.

🌊 Fairly flashyResponds fairly quickly to rain, with moderate baseflow between events.
Your catchment is all the land that drains rainfall into the river above this gauge. Its character — how
steep, wet, wooded, urban or chalky that land is — decides how fast rain here turns into a rising river. A steep, bare or clay
catchment is “flashy” (rises and falls quickly, floods easily); a flat, chalk or well-wooded one is
slow and steady. The tiles below put numbers to that; the flow-duration curve reads left-to-right
from the river’s typical high flows (Q5) down to its low flows (Q95) — a steep curve means a flashy river.

Non-standard broad crested weir by-passed at high flows but providing accurate flows at lower levels - replaced a side contracted flume in 1994. Heavily influenced by Blithfield reservoir.
More detail
The catchment
Catchment mainly drains Keuper Marl and subordinate sandstone, but widely blanketed with Boulder Clay and glacial sand and gravel. Land use mixed farming. Pre-reservoir FARL2015 (for WINFAP 5.3 or later) or FARL (for earlier versions of WINFAP) should be used with these records because the peak flow data after the reservoir started impounding is rejected. Pre- and post-reservoir values for FARL2015 are 0.9915 and 0.8294, respectively. Pre- and post-reservoir values for FARL are 0.998 and 0.873, respectively.
The station
Originally a side contracted flume with pilot tube tapping. Since 1994 a permanent non-standard, broad crested weir. Pre-barrage fish pass downstream of the weir.
How it measures flow
Station bypassed above 13.3 cumecs. Various methods used to rate the flume: temporary sharp-edged weir, formula, current meter and floats. Heavily influenced by Blithfield Reservoir, built in 1952. Naturalised flow series available. Gauged within structure using waded or roped ADCP. Flows have been known to be affected by in-channel and marginal vegetation both up and downstream, though is managed.
Flow regime
Blithfield reservoir built in 1952 - heavily influences the catchment (controls 75% of catchment area).
The flow record
Early data is from before the reservoir impounded and therefore does not form a continuous series with present-day records. Post-reservoir data added to the holdings in v12 but rejected for flood estimation. Full period of record peak flow data reviewed and released in September 2023 (WINFAP Files v12).
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Blithe at Hamstall Ridware flooding today?
The current level is 0.11m, which is within the typical range of 0.10 to 0.80m. Flooding is unlikely at this level.
Is the river level rising or falling at Hamstall Ridware?
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.
What is a normal level for the River Blithe at Hamstall Ridware?
The typical range at this station is 0.10m to 0.80m, based on Environment Agency historical data. Levels above 0.80m are higher than usually seen and may indicate a flood risk.
How often is this river level data updated?
Readings are supplied by the Environment Agency gauge. FloodRadar checks for updates roughly every 15 minutes; the timestamp above shows how recent the latest available reading is.
