Very mild temperature and a significant amount of rain have been observed throughout the Kawartha Conservation watershed over the last 24 hours. The air temperature gauge at the Port Perry weather station reported a high of 10°C, with 12°C recorded at Blackstock.

As expected, local rivers and streams have responded to increased runoff and are currently flowing in dangerously high water levels and velocities. Some streams have exceeded their bank full levels. Water accumulation has been observed in low laying areas, areas with poor or impeded drainage, and floodplains.
Environment Canada forecasts a very rapid drop in air temperature during the course of the day today. Rain will turn into snow. Very cold and dry weather is expected for the next two days.
Under these circumstances, water levels in local watercourses will stabilize and start declining. However, all rivers, streams, and lakes should be considered extremely dangerous. Riverbanks are slippery and unsafe; ice cover where it exists is unstable and hazardous. Kawartha Conservation is warning all residents to stay away from water bodies, as well as water structures such as bridges, culverts, and dams. Children should be warned of dangerous conditions and caregivers should maintain a close watch on children who are outside.
This Watershed Conditions Statement-Water Safety will be in effect through Saturday, Jan 13th, 2018.
Kawartha Conservation will continue monitoring local watercourses and notify the public and municipalities within its watershed jurisdiction of any changes. If you are aware of or have concerns about flooding, please contact Kawartha Conservation at 705-328-2271 or 705-344-0155 after hours.
