Catchment Character

🌊 Mixed response A 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.

About this gauge

Model tested trapezoidal flume and flanking broad-crested weirs within a vertical concrete side walls. Originally the site was built in the 1960s.

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

Frequently asked questions

Is the Rea Brook at Hookagate flooding today?

The current level is 0.10m, 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 7 days of measurements, 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. 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.

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 taken by the Environment Agency gauge roughly every 15 minutes and FloodRadar refreshes its data continuously, so the level shown is normally less than an hour old.
