SPRING SAFETY MESSAGE: BE CAREFUL AROUND WATERWAYS

Hazardous conditions on and around bodies of water

Credit Valley Conservation (CVC) is reminding residents of the dangers on and near local streams, rivers, ponds and lakes, particularly around this time of year. CVC urges people to exercise caution, and keep family members and pets away from the edges of all waterways as warmer spring weather approaches.

In spring we look forward to warmer weather and being outdoors. Warmer weather, however, usually brings rain, melting snow and shifting ice which can contribute to higher, faster flowing water in watercourses. Slippery, unstable streambanks and extremely cold water temperatures can also lead to very hazardous conditions close to any water body.

The Credit River Watershed has received a significant amount of snow this winter. A few recent thaws have helped decrease the existing snowpack. Melting snow due to warmer temperatures combined with spring rainfall and frozen ground conditions could contribute to higher water levels and increased water speeds in local watercourses.

There is still significant ice cover throughout the watershed. Several ice jams remain grounded along the Credit River at Barber (Paper) Mill Dam in Halton Hills, the Ferndale Park in Caledon and at Meadowvale Park in Mississauga. 

Remaining ice jams and ice cover on watercourses will weaken and become unstable with warmer temperatures. CVC continues to work with municipal emergency services to keep them constantly informed about current and changing conditions within local watercourses.

CVC urges people to exercise caution and keep family members and pets away from the edges of all waterways and off frozen water bodies, which are extremely unsafe.

WATERSHED CONDITIONS STATEMENT

Friday, Saturday and Sunday’s forecast calls for continued warm daytime temperatures across Southern Ontario.  Temperatures will peak at the mid to high single digits.  The current forecasted rainfall amount ranges from 10-20 mm over the weekend with an additional 5-10 mm of rain possible from convective precipitation (thunderstorm) overnight Saturday into Sunday morning.  On Sunday sustained winds up to 65 km/h from the west-southwest are forecasted with gusts exceeding 100km/h. 

Several ice jams remained grounded along the Credit River at the Ferndale Park, Barber (Paper) Mill Dam and Meadowvale Park.  Approximately 1.5 km of ice is backed up at the Barber Mill Dam in Glen Williams.  New river ice has formed at some locations since the previous ice break up event.  

The forecasted maximum 30mm of rain along with melting of the existing snow pack would be sufficient to break up the newly formed river ice, mobilize the grounded ice jams and potentially overtop the Barber Mill Dam sending ice downstream.  

Furthermore, the ice will lose its strength as the temperatures increase.  Under the proper loading and temperature conditions, it is possible for the existing grounded ice jam to shift or collapse under its own weight.  Once any type of movement initiates, the grounded ice jam may no longer be stable.  This is especially true if the movement occurs near the front (downstream or toe end) of the jam where a few critical pieces of ice could be holding back the entire ice jam.  

All watercourses in our area will experience higher than normal water levels.  An ice jam breaking lose will create extremely hazardous conditions.  As a result, local streams and rivers will become dangerous, especially in the vicinity of culverts, bridges and dams.  Children should be warned to stay away from all watercourses.  Furthermore, residents should heed to the warnings of first responders. 

High winds on Sunday could create hazardous conditions along the shoreline.  The forecasted west to southwest winds may result in higher lake levels, erosion of shorelines and trails along the shoreline could be impacted.  

CVC will continue to closely monitor weather and water levels in the watershed.  The Flood Outlook Statement will be in effect through Tue-Feb-26-2019 or until further notice. 

For more information on this Flood Outlook Statement, contact the CVC during office hours at 905-670-1615.  To report a flood afterhours, please call 1-800-215-8505.  Media inquiries should be directed to Maureen Pogue, 905-670-1615, ext. 242 or 647-271-5643. 

Call 911 if you require assistance from Emergency Services. 

WATERSHED CONDITIONS STATEMENT

Credit Valley Conservation (CVC) is advising that Environment Canada is forecasting mixed precipitation of 5-10 mm, along with warmer temperatures for this weekend. Rain will begin on Sunday with temperatures up to +3oC and continue into Monday with light showers and temperatures up to +7o C.

The mix of above-zero temperatures, rain, and partial melting of the snowpack are expected to increase runoff, water levels and flows in the watercourses throughout the watershed. With increased temperatures, there is a possibility of breaking up of the ice cover in watercourses, resulting in ice jams and increased water levels.

While flooding of the Credit River and its major tributaries is not expected, higher water levels and flows will result in local streams and rivers becoming dangerous, especially in the vicinity of culverts, bridges and dams.  Children should be warned to stay away from all watercourses.   

CVC will continue to closely monitor weather and water levels in the watershed.  The Watershed Conditions Statement for Water Safety will be in effect through to Tuesday February 5th, 2019, or until further notice.  

For more information on this Water Safety Statement, contact CVC during office hours at 905- 670-1615.  To report a flood afterhours, please call 1-800-215-8505.

Spring Safety Message: Exercise Caution Around Waterways

Credit Valley Conservation (CVC) is reminding residents of the dangers that exist on and near local streams, rivers, ponds and lakes, particularly around this time of year. CVC urges people to exercise caution and keep family members and pets away from the edges of all waterways.

Spring is quickly approaching and we look forward to warmer weather and being outdoors. Warmer weather usually brings more snowmelt, rain and ice breaking up along streams, rivers, ponds and lakes. During this time of year we can expect higher, faster flowing water in most watercourses. In addition, slippery and unstable stream banks and extremely cold water temperatures can lead to very hazardous conditions close to any water body.
