WATERSHED CONDITIONS STATEMENT – WATER SAFETY
DATE: March 13, 2015
TIME: 3:00 p.m.
Message sent on the basis of information received from:

- Trent-Severn Waterway
Southern Ontario, including the Kawartha Conservation watershed, has experienced spring weather over the past week, with above freezing temperatures and lots of sunshine. Temperatures cool down at night to below the freezing mark. Under these weather conditions, the snowpack around the watershed has started melting gradually, releasing some run-off. Observed weather conditions are favourable for gradual, longer snow melt, which decreases potential for flooding. No significant precipitation is predicted next week.
Local rivers and streams are still flowing at low levels. However, as warmer weather is forecast into next week, run-off from melting snow will intensify, with stream water levels and velocities increasing gradually.
Significant ice cover has developed on local rivers, streams and lakes over the winter months. With warmer weather and increase water levels and flow velocities, ice cover has started to weaken and may break-up. There is a potential for ice jams.
Trent-Severn Waterway officials are maintaining low levels in the larger lakes across the Kawarthas according to their water level management strategy. They monitor the situation closely and undertake dam stop logging operations as required.
While no flooding is anticipated at this time, water accumulation will occur in low-lying areas, road ditches, and areas with poor drainage. Smaller streams and creeks will respond quickly to the snow melt and precipitation, but larger water bodies will take longer to react.
All local rivers, streams, and lakes should be considered extremely dangerous; riverbanks will be very slippery and unsafe. Thinning ice cover is becoming 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 Wednesday, March 18, 2015.
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 or ice jams, please contact Kawartha Conservation at 705.328.2271 or 705.344.0155 after hours.
