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.

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.
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.

Flood history near this gauge
Official Environment Agency warnings issued since 2006 for the 34 flood
areas linked to this gauge (nearest 0.5 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.
See also the Lenton flood history.

Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
Catchment Character
🌊 Urban & flashyHeavily built-up — rain runs off hard surfaces fast, so levels can spike within hours of heavy rain.
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).

Station in central Nottingham gauging the baseflow dominated regime of the Leen. Twin concrete channels in urban area.
More detail
The catchment
Moderate to low relief catchment draining south into Nottingham. Geology predominantly Magnesian Limestone in the west with Permian Mudstones and Sherwood Sandstones to the east. Significant urban fraction, approx 50%, in lower catchment otherwise arable and grazing land use.
The station
Two rectangular concrete channels, each 3.05m wide, 2.75m deep, separated by divide wall 1m high. All flows contained. Closed 1984, reopened in 1991 as multiple Ultrasonic operation. Laser flow gauge operational from 2023. Station added to peak flows dataset in August 2024 (WINFAP Files v13).
How it measures flow
Use pre-ultrasonic record with care especially at low flows due to unstable rating. Informal low flow controls installed in 1981 produced some improvement.
Flow regime
An extremely urban, flashy catchment producing a very spiky data record. Minor net disturbance to baseflow dominated flow regime. There is also a high level of flood attenuation in the catchment, with a number of dams and storage reservoirs that can hold back flow and level.
The flow record
Peak Flows available from the Ultrasonic gauge only after WY1991/1992.

Frequently asked questions
Is the River Leen at Lenton flooding today?
The current level is 0.10m, which is within the typical range of 0.08 to 1.00m. Flooding is unlikely at this level.
Is the river level rising or falling at Lenton?
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 Leen at Lenton?
The typical range at this station is 0.08m to 1.00m, based on Environment Agency historical data. Levels above 1.00m 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.
