Astley Brook

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

Astley Brook is a stream on Ordnance Survey’s river map near Astley, Wigan, with about 600 m of mapped channel. On the map it flows into Town Brook, which flows on into Moss Brook (Black Brook), then Glaze Brook; beyond that the map has a gap, so where it goes next is not known.

Next gauge downstream

No gauge measures Astley 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.

1 storm overflow is placed on this stream on the river map. Each status is the water company’s own monitor.

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 →

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 Astley 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.
