The Isis

OURCs displays flags on their website to indicate the current stream conditions on both the Isis and Godstow reaches. In increasing levels of stream, the possible levels are: green, blue^*, amber, and red, with each flag representing a different set of restrictions which apply. During periods where the flag is not being maintained, a grey flag is shown, and during exceptionally high flooding, a black flag may be displayed. Information about the restrictions in force for any given flag and how the flag itself it decided, can be found by following the link above.

We poll the OURCs website every few minutes and record the flag displayed, when OURCs report that the flag was first shown, and who made that change. We also record the first and last times that our data collection observes that flag status, although only the latter is shown on this page since we have no reason to doubt the timekeeping of the OURCs website at this stage. For curiosity's sake, we also display the length of time each flag was shown for. On the Isis, we note that amber flag is typically only shown for a day or two, while blue flag is typically shown for closer to a week.

^* Godstow does not have a blue flag.
