Salary Brook

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

Salary Brook is a stream on Ordnance Survey’s river map near Crockleford Heath, Essex, with about 5.6 km of mapped channel. On the map it flows into the River Colne and out to the sea.

Next gauge downstream

None: the lower end of Salary Brook is tidal on the river map. The tide carries water past a gauge both ways there, so no gauge is named downstream of it.

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 Salary 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.
