Flooded Thames in Winter 2014

River Safety and Risk Assessment

The colour of the flag is determined by the Oxford University Rowing Club's (OURCs) and represents how fast (and therefore how dangerous) the stream is on the Isis and consequently shows which OURCs rules are in force.

Before setting out on the water, each person should complete a number of checks which are noted below  as part of a dynamic risk assessment.

In summary, if an organised club session, the experienced coach on duty will make a judgement call based on competency of the participants and on the conditions. If you are going on the water outside of an organised club session, it's your own responsibility to make the call. The default position for all is "Any doubt, don’t go out!"


There are a number of sources of information about the river conditions.

OURC Flag Status

When the river level is above normal, Anu's Isis Level gives a good picture of what is happening. It also include links to one of the Oxford weather stations and the Osney and Iffley Lock river gauges.

City of Oxford Rowing Club have an online weather station that gives current temperature and wind speed when it is operational.


Rowing and kayaking can also be dangerous if it is too windy, too foggy, too dark, too cold (especially if there is ice in the river) or if a storm is due e.g. with lightning.
