South Oxford Flood Action Group have included a useful page on their website with a table showing river levels upstream of Oxford in the Thames catchment. They also provide some guidance on how historical levels relate to the severity of flooding in South Oxford. The text reads as follows:
Because of the complex influence of upstream river levels on flooding that can occur in South Oxford, it is not possible to have a failsafe means to predict if and when flooding will occur. However, the EA’s upstream river level monitoring data can give us some idea when flooding might occur and how serious it might be. Here are two rules of thumb:
- since the early 2000s we have had major floods in South Oxford when the level of the Seacourt Stream at Minns Estate rises above 2.69 metres
- often, but not always, if the river level on the downstream side of Shifford Lock reaches 3.90 metres and the river level on the downstream side of Northmoor Lock reaches 3.58 metres there will likely be a major flood in South Oxford. A rise in the river levels at Shifford Lock can often be seen in the Hinksey Stream in South Oxford about 12-24 hours later.
These same levels would also apply to flooding in West Oxford. River levels in Oxford are currently very similar to those we same on 21 December last year.
