Maidenhead is a town in the English county of Berkshire. The River Thames runs throught the town.
In 2009, there was extreme flooding of the Thames in Maidenhead due to lots of rain (or possibly caused by two local Anomalies). Some Velociraptors came through an Anomaly and sheltered in a bus stop and elsewhere two Deinosuchus came through another Anomaly. The Anomaly Research Centre team arrived and dealt with the dinosaurs and captured the crocodiles.
