With more rain expected over the next few days, conservation officials will be keeping tabs on area waterways.
Officials with the St Clair Region Conservation Authority say some areas could see between 50 and 100mm of rain this week.
High amounts of rainfall in a short period of time can lead to increased runoff and flash flooding, particularly in urban areas.
Residents near streams and the Sydenham River may experience water levels rising quickly as a result of high intensity rainfall.
