FLOOD WARNING – KAWARTHA LAKES – Update

A FLOOD WARNING remains in place for the shoreline areas of Balsam, Cameron, Sturgeon and Pigeon lakes. There is potential for flooding to occur along shorelines, in near shore areas, and in low-lying areas as a large volume of water passes through the Trent River system. More rain, 25 to 35 mm, is forecast for tomorrow. As a result, the high water levels in the large Kawartha Lakes will be sustained, as northern tributaries such as the Burnt and Gull rivers continue to provide exceptionally high inflows. Kawartha Conservation asks to exercise extreme caution around all watercourses. For assistance in the event of a flood, contact your municipality.

DATE:    April 25, 2019

TIME:    4:00 pm              

 Message sent on the basis of information received from:

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

Affected Municipalities:

  • City of Kawartha Lakes
  • Municipality of Trent Lakes 

A FLOOD WARNING remains in place for the shoreline areas of Balsam, Cameron, Sturgeon and Pigeon lakes. There is potential for flooding to occur along shorelines, in near shore areas, and in low-lying areas as a large volume of water passes through the Trent River system.

Water levels in the large Kawartha Lakes continued increasing over the last 24 hours. The observed rates of rise were as following.

  • Balsam Lake 3 cm
  • Cameron Lake 8 cm
  • Sturgeon Lake 3 cm
  • Pigeon Lake 9 cm.

All lakes, with the exception of Sturgeon, are above their full levels; Sturgeon Lake is expected to reach its ‘full’ conditions tomorrow.

More rain, 25 to 35 mm, is forecast for tomorrow. As a result, the high water levels in the large Kawartha Lakes will be sustained, as northern tributaries such as the Burnt and Gull rivers continue to provide exceptionally high inflows. Water levels are expected to increase in rates, similar to those observed over the last 24 hours.

Lake Scugog has remained stable over the last 24 hour, but will also increase in response to the upcoming precipitation.

Trent Severn Waterway’s officials monitor this situation closely. They are reassessing the conditions on a daily basis and adjusting the flows through water control structures to relieve pressure in the affected areas.

Under these circumstances, all near shore areas should be considered dangerous. Currents in the vicinity of dams are swift and treacherous, banks wet, slippery and may be undercut. Kawartha Conservation is warning all residents to stay a safe distance from all 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.

Shoreline residents are advised to take precautions to protect themselves and their property, to monitor water levels closely, and contact their local municipality should any threat of flooding develop.

Municipalities are advised to monitor areas historically known for flooding and be prepared to respond to high water situations as they occur. Residents are advised to contact their municipalities should a flood threat develop. Local municipalities are first to respond to and assist with flood emergencies.

Additional information from the TSW is available at the Water Management InfoNet web page https://www.pc.gc.ca/en/lhn-nhs/on/trentsevern/info/infonet .

Burnt and Gull River levels are monitored by staff from the Ministry of Natural Resources and Forestry (MNRF). Residents along these two rivers are requested to direct any questions concerning water levels to the MNRF Minden Area office at 705-286-5207 or refer to the messages issued by the Ministry of Natural Resources and Forestry (MNRF) at https://www.ontario.ca/law-and-safety/flood-forecasting-and-warning-program .

For assistance in the event of a flood, and to obtain sandbags, please contact your local municipality directly.

Kawartha Conservation will continue monitoring local watercourses and notify the public and municipalities within its watershed jurisdiction of any changes. We are in close communication with partner agencies such as the Trent Severn Waterway, Ministry of Natural Resources and Forestry, and neighbouring Conservation Authorities on this situation.

This Flood Warning will be in effect until Monday, Apr 29th 2019. If you are aware of or have concerns about flooding, please contact Kawartha Conservation at 705.328.2271 or 705.344.0155 after hours.
