WATERSHED CONDITIONS STATEMENT    WATER SAFETY

DATE:                   March 18, 2015

TIME:                   3:00 p.m.

Message sent on the basis of information received from:

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

Kawartha Conservation advises that the Watershed Conditions Statement - Water Safety remains in effect. The public and especially children are advised to stay away from local waterbodies as high flows, unstable ice cover and slippery banks result in extremely dangerous conditions.

As a result of warmer weather experienced over the past week, the snowpack around the watershed has decreased substantially. Smaller creeks and streams have already cleared from ice. Ice cover on larger watercourses and lakes continues to deteriorate. A moderate increase in local river and stream water levels, as well as accumulation of water in low-lying areas, road ditches, and areas with poor drainage has been observed.

Trent-Severn Waterway officials report that the water levels in the larger lakes across the Kawarthas are lower than normal for this time of the year due to low inflows experienced in the winter months. It is estimated that storage capacity is adequate to accept run off from the existing snowpack. The TSW monitors this situation closely and undertakes dam stop logging operations as required.

As current weather pattern is expected to persist, gradual melting of snow will continue. While no flooding is anticipated at this time, local watercourses will continue to flow at higher than usual water levels and velocities. As a result, all local rivers, streams, and lakes continue to be extremely dangerous; riverbanks are very slippery and unsafe. Ice cover where it remains 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.

This Watershed Conditions Statement - Water Safety will be in effect through Monday, March 23, 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.

WATERSHED CONDITIONS STATEMENT    WATER SAFETY

 

DATE:                   March 13, 2015

TIME:                   3:00 p.m.

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.
