💧 Storm overflows upstream of this gauge

None of the storm overflows FloodRadar holds is traced upstream of this gauge on the mapped river network. That is not the same as none: the map leaves out many small streams and culverts, so an overflow it cannot place may still drain here, and not every company publishes every overflow. Those nearby are listed below.

4 other overflows within 6 km are downstream of this gauge or on another branch of the river network, so they are not listed.

These are the water companies' monitor statuses; a spill does not by itself explain a change in the gauge level. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels. Explore the sewage map →

Catchment Character

🌊 Mixed response A balance of quick runoff and slower groundwater baseflow.

Your catchment is all the land that drains rainfall into the river above this gauge. Its character — how steep, wet, wooded, urban or chalky that land is — decides how fast rain here turns into a rising river. A steep, bare or clay catchment is “flashy” (rises and falls quickly, floods easily); a flat, chalk or well-wooded one is slow and steady. The tiles below put numbers to that; the flow-duration curve reads left-to-right from the river’s typical high flows (Q5) down to its low flows (Q95) — a steep curve means a flashy river.

The physical character of the land that drains to this gauge, and how it shapes its flood response — from the National River Flow Archive (UKCEH).

About this gauge

Ultrasonic station opened in December 2005 and replaced 27058. Rating used to infill at stage less than 1m.

More detail

The catchment

Small, linear catchment draining the North York Moors. Geology: shales, sandstones and limestones. Moorland headwaters, arable in lower catchment, significant forestry.

The station

Ultrasonic gauging station opened 02-12-2005 to replace 27058 (Riccal at Crook House Farm) which was 1.3km upstream. Problems of power loss to the ultrasonics throughout the period of record.

How it measures flow

Rating developed in 2011 which is used to infill missing data at a stage of less than 1m; where rating has been used to infill data over a stage of 1m, data should be used with caution.

The flow record

Missing data 22/02/2010-02/03/2010, due to power issues at the site.
