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.

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.
28 storm overflows are traced upstream of this gauge, the nearest 2.9 km away along the river. 0 report discharging now, 27 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

11 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.
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).

Flow-Duration Curve
Daily flow (m³/s) exceeded each % of the time — a steep curve is flashy, a flat one is steady. Q5 high · Q50 median · Q95 low.
Moderate relief catchment, draining west from the Oolitic Limestone scarp. Predominantly Boulder Clay overlying Liassic clays. Rural catchment, mixed farming, containing Melton Mowbray.
The station
Ultrasonic time of flight gauge since October 2018, providing good quality data at low and high flows. Side-looking ADCP gauge 2012-2018. Electromagnetic gauge in use 1982-2012, replacing the original crump weir 4.6m wide which was originally installed in 1967.
How it measures flow
All flows contained. Site difficult to gauge; very low velocities at low flows and station bypassed at high flows. Three peak flow ratings applied across period of record.
Flow regime
Fast response to rainfall and significant augmentation from WRW.
The flow record
Issues with low flow data during ADCP period due to low channel velocities in a deep river section. Levels indicate the March 1975 event may have been higher than the April 1998 event, but the magnitude cannot be verified due to complications with the rating history.

Frequently asked questions
Is the River Wreake at Syston flooding today?
The current level is 1.44m, which is within the typical range of 1.43 to 2.77m. Flooding is unlikely at this level.
Is the river level rising or falling at Syston?
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 Wreake at Syston?
The typical range at this station is 1.43m to 2.77m, based on Environment Agency historical data. Levels above 2.77m 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.
