Lemon Gill

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

Lemon Gill is a stream on Ordnance Survey’s river map near Grinton, North Yorkshire, with about 540 m of mapped channel. On the map it flows into Cogden Gill, which flows on into Cogden Beck, then the River Swale, then the River Ure, then the River Ouse, then the River Humber and out to the sea.

Next gauge downstream

Richmond Lownthwaite Bridge on the River Swale, about 16 km along the river below where Lemon Gill ends on the map.

After that, Catterick Bridge, about 27 km along the river.

No gauge measures Lemon Gill 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 Environment Agency sampling point is 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 Lemon Gill 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.
