Flood Potential: Moderate
Ice Jam Potential: Low

Issued to: Local municipalities and school boards, local conservation authorities, emergency response agencies, health unit, media.

Date: April 4 2023 (3:00pm)

The Nottawasaga Valley Conservation Authority advises of moderate rain across the watershed over the next 36 hours. Although no major flooding is anticipated, local streams and rivers could become dangerous, especially around culverts, bridges, and dams.

The public and especially children are advised to stay away from all area water bodies as unstable ice cover, slippery banks and fast flowing watercourses will result in dangerous conditions.

The NVCA watershed received 15-30mm of precipitation this past weekend. As a result of recent warm temperatures, rainfall and snowmelt, rivers and creeks within the NVCA’s watershed are experiencing higher than normal flows and water levels. While no widespread flooding is occurring, water levels of the Lower Nottawasaga River are continuing to rise with 25mm of rain expected, beginning tonight Tuesday April 4th until early morning Thursday April 6th.

Although no major flooding is anticipated, local conditions will vary. At this time of year there is always the potential for localized flooding and ice jams where river ice is present.

The Nottawasaga Valley Conservation Authority continues to monitor river and stream conditions and will issue additional messages as conditions warrant. This Flood Outlook statement will be in effect until (or updated before) 4:00pm Friday April 7, 2023.
