Nether Green Brook

A stream near Eastwood, Derbyshire. No gauge of its own: what the river map and the banked data say about it.

Nether Green Brook is a stream on Ordnance Survey’s river map near Eastwood, Derbyshire, with about 1.4 km of mapped channel. On the map it flows into the River Erewash, which flows on into the River Trent, then the River Humber and out to the sea.

Next gauge downstream

Shipley Gate on the River Erewash, about 3.6 km along the river below where Nether Green Brook ends on the map.

After that, Sandiacre, about 17 km along the river.

No gauge measures Nether Green Brook itself. A gauge downstream shows water that has already passed it, mixed with everything else that has joined on the way, so it says nothing exact about this stream.

Storm overflows on Nether Green Brook

2 storm overflows are placed on this stream on the river map. Each status is the water company’s own monitor.

Eastwood - Mansfield Road CSO Not discharging
Severn Trent Water · into Tributary Of River Erewash · 2025: 18 spills, 38 h
Jacksdale - Main Road (CSO) Not discharging
Severn Trent Water · into Tributary Of River Erewash · 2025: 27 spills, 95 h

A status says whether an overflow is discharging now, never how much or why. A monitor that is offline or has not reported is not “not discharging”. Sewage in Britain’s rivers →

Water-sampling points on Nether Green Brook

2 Environment Agency sampling points are placed on this stream. These are dated samples taken by hand, not live readings, and FloodRadar does not grade them.

Nethergreen Brook at Eastwood

A sample is taken on a date; it says nothing about the water today. A sample below an overflow does not by itself show where anything in it came from.

What this page can and cannot tell you

Its line, its name and where it flows come from Ordnance Survey’s river map (OS Open Rivers, edition 2026-04), which leaves out many small streams, ditches and culverts. “Flows into” is the map’s word: a channel that is not on the map is not shown here, which does not mean it is not there.
No gauge measures Nether Green Brook itself, so its own level is not known here.
Storm overflows are listed only where the river map places them on this stream; an overflow it could not place is not counted.
Water samples are England’s only (the Environment Agency’s archive), placed where the map can place their sampling point.
Nothing on this page says whether any place floods. For an address, see its postcode page.
