You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.
Beta. You'll be notified when a flood wave detected at an upstream gauge is forecast to reach this station, with an estimated arrival time. Accuracy improves as we verify more waves.
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.
5 storm overflows are traced upstream of this gauge, the nearest 1.6 km away along the river. 0 report discharging now, 5 report not discharging.

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 →

Flood history near this gauge
Official Environment Agency warnings issued since 2006 for the 4 flood
areas linked to this gauge (nearest 4.3 km away).
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.

🌊 Mixed responseA balance of quick runoff and slower groundwater baseflow.
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.

More detail
The catchment
Broad, flat main channel flanked by steeply graded streams. Complex geology; s'sts and shales (Pre-Cambrian to Silurian). Lower reaches entirely covered by Boulder Clay and fluvio-glacial sand and gravel. Moorland and low grade agriculture.
The station
Model tested trapezoidal flume and flanking broad-crested weirs within a vertical concrete side walls, 7.3m apart. Originally the site was built in the 1960s, and although previously there were concerns about potential erosion on site, low flow gaugings confirm there are no issues at site.
How it measures flow
Left bank inundated at high flows, however velocities in general are low on site, therefore extrapolation is considered reasonable. All flows are contained by the downstream road bridge, which is used to gauge high flows. Theoretical rating is applied across the period of record. Rating is thought to be reliable to 1.5mASD, but further gaugings are needed to confirm this.
Flow regime
Substantially natural catchment. Minor effects from sewage at lowest flows.
The flow record
Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the Rea Brook at Hookagate flooding today?
The current level is 0.12m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Hookagate?
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 Rea Brook at Hookagate?
The typical range at this station is 0.15m to 1.10m, based on Environment Agency historical data. Levels above 1.10m 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.
