From late Tuesday evening through Wednesday, the watershed received an unusually large amount of rain for this time of the year. Around the watershed, rainfall totals ranging from 60 mm to over 100 mm were recorded. As a result, there have been unusually high flows on the Thames River, more similar to a spring flood event. Thames River water levels peaked in London on Thursday evening, and around the middle of the day on Saturday around Dutton. There is no rain in the forecast for the next few days.
Many local watercourses across the watershed had reached bank full conditions or spilled their banks. Water levels on those watercourses have now dropping throughout the watershed. However, some may still remain high in downstream areas influenced by high water on the Thames River.
