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.
Get notified when recent rainfall near this gauge crosses its learnt rise trigger — an early "watch"
signal, typically hours before a rise. Experimental; not an official flood warning.

Nimbus beta
Experimental model fusing soil moisture, river flow, groundwater and catchment
character. The shaded band is its 10–90% range, widened so that about 80% of recent outcomes fall inside it.
Under evaluation — not yet promoted, so treat as a second opinion. The nearest rain gauge has sent no readings in the last day, so Nimbus has no recent measured rain to work from here.
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.

None of the storm overflows FloodRadar holds is traced upstream of this gauge on the mapped river network. That is not the same as none: the map leaves out many small streams and culverts, so an overflow it cannot place may still drain here, and not every company publishes every overflow. Those nearby are listed below.
Nearby, connection not known
Within 6 km in a straight line, but the river map cannot say whether their water passes this gauge.
Thames Water · into Cranleigh Waters · 3.9 km away in a straight line · no mapped watercourse close enough to be sure

Not discharging now
1 other overflow within 6 km is downstream of this gauge or on another branch of the river network, so it is 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.

🌊 Groundwater-fedSlow and steady — fed largely by groundwater, so levels change gradually, not in sudden spikes.
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.
The physical character of the land that drains to this gauge, and how it shapes its flood response — from the National River Flow Archive (UKCEH).

More detail
The catchment
Small, relatively steep, rural catchment draining from the Winterfold Forest and Hurtwood. Mainly pervious , developed principally on Hythe Beds (Upper Greensand). There is substantial woodland and appreciable urban development in the lower catchment.
The station
Rectangular thin-plate weir, 2.7m broad.
How it measures flow
Flood discharges can exceed weir capacity and bypassing occurs on the right bank; some leakage below weir plate also suspected to have occurred. Heavy accretion (silting) u/s needs dredging regularly as it causes the weir to underestimate flow. Weir damaged in 1996. One rating applied across period of record. Rating is accurate before 1983. No gaugings 1983 to 1993 but post-1993 rating may generally underestimate GDFs and peak flows.
Flow regime
Baseflow dominated regime but responsive on occasions. Apparent very late response (autumn) to winter recharge. Low flow pattern affected by inputs from artesian boreholes (supporting watercress beds). Runoff is less diminished since the closure of the Thames Water gw abstraction near to the station.
The flow record
Some peak flows are beyond the upper limit of the rating and so should be treated with caution.(e.g. during 2012). Low flow data from June & July 1996 maybe underestimated due to damaged sustained by the weir. Full period of record peak flow data reviewed and released in September 2020 (WINFAP Files v9).

Frequently asked questions
Is the Law Brook at Albury flooding today?
The current level is 0.09m, which is within the typical range of 0.05 to 0.29m. Flooding is unlikely at this level.
Is the river level rising or falling at Albury?
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 Law Brook at Albury?
The typical range at this station is 0.05m to 0.29m, based on Environment Agency historical data. Levels above 0.29m 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.
