Message sent based on information received from:

• Kawartha Conservation Flood Forecasting Network
• Ministry of Natural Resources and Forestry - Surface Water Monitoring Centre 
• Environment Canada
• Trent-Severn Waterway 

Kawartha Conservation advises that the Surface Water Monitoring Centre of the Ministry of Natural Resources and Forestry (MNRF) is tracking a strong low-pressure system moving into Ontario tonight (Thursday, March 16) and slowly moving across the province for the next two days.  The system will bring warmer air and significant amounts of precipitation.  Air temperatures in Southern Ontario are expected to stay above the freezing mark overnight, reaching 7-10 C on Friday.  Total precipitation accumulation amounts for the duration of the storm are forecast to reach 20-30mm in Southern Region, with the bulk of the rain occurring on Friday.  

A considerable snowpack still exists in the Kawartha Watershed. This snowpack combined with warmer temperatures, will cause increased runoff from precipitation and snow melt, therefore, watercourses can be dangerous, and Kawartha Conservation is warning residents to stay a safe distance from all streams and rivers, as well as water structures such as bridges, culverts, and dams, and that ice conditions, particularly in areas of moving water, may be unsafe due to the warming temperatures. Riverbanks can be slippery, especially during rain events with snow and ice already on the ground, children should be warned of the dangerous conditions, and supervised while outside.

Widespread flooding is not anticipated, however water levels and flows in watercourses across the Kawartha Conservation watershed jurisdiction remain higher than normal for this time of year. 

This Watershed Condition Statement – Water Safety will be in effect through Sunday March 19, 2023.  

Kawartha Conservation will continue monitoring local watercourses and notify the public and municipalities within its watershed jurisdiction of any changes.
