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.

Under evaluation — not yet promoted, so treat as a second opinion.
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.
56 storm overflows are traced upstream of this gauge, the nearest 430 m away along the river. 0 report discharging now, 53 report not discharging, and for 3 the monitor is offline or has not reported, so their status is not known.

6 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.

🌊 Mixed responseA 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.

Velocity area station in a deep channel with long record of flows. Processing of flows ceased in 2004 as low flow rating poor due to shifting section control. Station replaced with downstream gauge at Whatstandwell.
More detail
The catchment
Responsive upland catchment. Geology predominantly Millstone Grit with some Coal Measures to the east and Carboniferous Limestone in the west draining The Wye. Peat covered moorlands occur in the headwaters with forestry and pasture elsewhere.
The station
Velocity area station about 20 m wide in a deep channel.
How it measures flow
Open channel site with cableway. Rated with two ratings applied across period of record, the most recent is valid from January-2001. No gaugings above bankfull but rating fits gaugings well up to the level of the highest gauged flow (3.1mASD). Highest floods will bypass along the adjacent A6 road.
Flow regime
Substantially affected by Derwent reservoirs and mill operation, particularly in the early record.
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Derwent at Matlock flooding today?
The current level is 0.64m, which is within the typical range of 0.29 to 2.50m. Flooding is unlikely at this level.
Is the river level rising or falling at Matlock?
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 Derwent at Matlock?
The typical range at this station is 0.29m to 2.50m, based on Environment Agency historical data. Levels above 2.50m 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.
