Get notified about Colwick — tick as many as you like, they all share the notify settings below.
Each one is saved as its own alert — pause or remove them individually any time.
Not an emergency service — if in danger call 999. Alerts rely on EA/SEPA/NRW data and are best-efforts. Terms
Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
Gauges connected to this river, and others nearby. A distance “by river” follows the river on the map; any other is in a straight line.
Distances by river: OS Open Rivers. Contains OS data © Crown copyright and database rights 2026.
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.
824 storm overflows are traced upstream of this gauge, the nearest 3.6 km away along the river. 2 report discharging now, 791 report not discharging, and for 31 the monitor is offline or has not reported, so their status is not known.
816 more further upstream, up to 147.7 km away along the river.
Also discharging now further upstream: Cromford Road - CSO No 3 (38.5 km), Matlock Bath - Dale Road (Coal Me- (76.5 km).
Within 6 km in a straight line, but the river map cannot say whether their water passes this gauge.
13 more within 6 km whose connection is not known.
2 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 →

In a typical year this gauge reaches its typical high of 3.60 m on about 8 days. This year so far: 12 days.
Counted from each day's highest reading. Days with missing or implausible readings are left out.
Official Environment Agency warnings issued since 2007 for the 33 flood areas linked to this gauge (nearest 0.4 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 Holme Pierrepont flood history.
Flood warnings and alerts are issued for whole areas. These are the 33 areas linked to this gauge, nearest first.
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 affected by: surface-water abstraction, reservoir influence, public water supply, groundwater abstraction, effluent returns, industrial / agricultural abstraction.

How this gauging station is built and how long it has measured (NRFA / UKCEH).
The current level is 1.04m, which is within the typical range of 1.01 to 3.60m. Flooding is unlikely at this level.
Based on the most recent readings, the level is currently rising. The chart above shows the last 12 hours of measurements by default (up to 7 days), updated roughly every 15 minutes.
The typical range at this station is 1.01m to 3.60m, based on Environment Agency historical data. Levels above 3.60m are higher than usually seen and may indicate a flood risk.
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.
