The Nottawasaga Valley Conservation Authority advises that the Flood Watch issued February 20, 2018 is continued for the Lower Nottawasaga River, including all areas downstream of Angus. The Flood Watch for the Upper and Middle Nottawasaga River is downgraded to a Flood Outlook Statement.
Approximately 20-40mm of rain has fallen across the watershed in the past week. Temperatures are forecast to remain above freezing through the week ahead.
Water levels in most rivers and streams are receding but remain elevated as a result of recent rainfall and snowmelt. The Nottawasaga River downstream of Angus to Wasaga Beach is expected to continue to rise through the weekend. Any additional rainfall on frozen or saturated ground will further increase water levels in area streams. Where river ice is still present, there is the potential for ice jams. Water could overflow banks and cause flooding in some areas. Widespread flooding is not anticipated at this time.
Municipalities, emergency services and individual landowners in flood-prone areas should be on alert.
Hazardous conditions may exist around all waterbodies, as there is a high risk of life-threatening injury if a person falls into the extremely cold water. The public and especially children are advised to stay away from all waterbodies.
The Nottawasaga Valley Conservation Authority continues to monitor river and stream conditions and will issue additional messages as conditions warrant. This Flood Watch Statement will be in effect until 4:00 p.m., Tuesday, February 27, 2018.
