Witney Flood Group
Welcome!
Our Demands for Witney
Proper maintenance of the river and ordinary watercourses including silt, fallen trees, obstructions
Witney Bridge may have to be redesigned or rebuilt – it acts as a dam during flooding conditions
Other land adjustments, such as the footpath across Langel Common, may be acting as a dam
River Level Gauges – now in key locations to properly assess trends, driven by facts
An Attenuation Scheme for Witney – between Worsham and Crawley, and for Hailey Road drain
Joined up thinking and teamwork – working together will get us far closer to solutions

How to Read Sensor Data
Guide to Dataset
History – Select view from the top right date ranges bar. Data can be downloaded for analysis.
Level Gauges – River level at each sensor location.
Location Map – Map view of sensor locations and current height readings.
What is Ordnance Datum?
Ordnance Datum Newlyn (ODN) is the reference value for altitude in the UK when measuring height above sea level. Observations from the tidal gauging station at Newlyn in Cornwall taken by the Ordnance Survey between 1915 and 1921 were the basis for mean sea level (MSL) to be determined.
Relevance in River Engineering
Ordnance Datum is used in every aspect of river engineering because water level is always the fundamental consideration. Here in Witney gauge boards are set to ODN and flood levels recorded against it. As the national standard applications such as topographical survey, mapping, flood modelling, improvement scheme design, construction and channel maintenance also work to ODN.
