Moss Brook (Black Brook)

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

Moss Brook (Black Brook) is a stream on Ordnance Survey’s river map near Lately Common, Wigan, with about 3.8 km of mapped channel. On the map it flows into Glaze Brook; beyond that the map has a gap, so where it goes next is not known.

No gauge measures Moss Brook (Black 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.

Water-sampling points on Moss Brook (Black Brook)

3 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.

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 Moss Brook (Black Brook) itself, so its own level is not known here.
No storm overflow is placed on this stream on the river map. That is not the same as none: the map cannot place every overflow.
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.
