EXPIRED | Flood Watch | Dec. 10, 2021


Message # 2021-16
Issued:   11:00 a.m., Friday December 10, 2021

Subject: FLOOD WATCH issued for all waterbodies/watercourses in the Otonabee Region watershed.

Issued to: Municipalities of Selwyn, Douro-Dummer, Asphodel-Norwood, Otonabee-South Monaghan, Cavan Monaghan, City of Kawartha Lakes, City of Peterborough and Trent Hills, and Otonabee Conservation’s other partners in flood emergency management.

A FLOOD WATCH is issued to alert municipalities and residents that flood conditions are a possibility.

Weather Forecast: A strong cold front will make its way into Southern Ontario today bringing warmer temperatures, rain, and strong winds.  Temperatures will be above normal for this time of year with a high of 6 degrees C Friday and up to 13 degrees C on Saturday before dropping below zero Saturday night.  Friday afternoon could see rainfall in the amounts of 10 to 15mm with an additional 10 to 20mm possible on Saturday.

Flood Threat:  With frozen ground conditions, the expected rainfall and potential heavy downpours, combined with warm temperatures and melting snow may cause minor flooding in low-lying areas. As a minimum, water pooling on roads and in low-lying areas and higher than normal water levels and flows can be expected, especially in the vicinity of culverts and bridges. Higher than normal water levels and flows will continue throughout the weekend as the expected rainfall and snow melt flushes through our waterways.

Residents are advised to be extremely cautious around all local lakes, rivers, streams, and creeks because shorelines/riverbanks will be slippery and could be undercut, and currents will be strong.  Road-side ditches, wetlands and other low-lying areas may experience unsafe ponding conditions. Dams and other water control/water conveyance structures are especially dangerous and should always be avoided.  

With this message, Otonabee Conservation is advising all area municipalities and residents to prepare themselves for possible flooding. Area water data and information can be monitored on-line at:

  1. Trent-Severn Waterway’s Water Management InfoNet
  2. Water Survey of Canada Real-Time Hydrometric Data 
  3. Otonabee Conservation Precipitation and Water Level Data

This FLOOD WATCH message will expire Tuesday, December 13, 2021, at 4 p.m. unless updated prior to this date and time.
