St. Thomas, February 5, 2019 – KCCA staff are monitoring an ice jam located just
north of Port Stanley. "The ice jam is causing water to back up around Southwold
Wall, where Roberts Line and Sparta Line meet," says Jennifer Dow, KCCA's water
conservation supervisor. "Water levels have been slowly dropping over the last eight
hours and will continue to drop overnight until a wide band of freezing rain moves
through the area early Wednesday morning," says Dow. The current Environment Canada
forecast indicates that southern Ontario will receive 10-15mm of freezing rain on
Wednesday and 10-15mm of rain on Thursday.
Ice jams may cause water levels to change quickly and unexpectedly. The extent of
the flooding will be dependent on the amount of rain the area receives over the
next two days. Residents are reminded to monitor their local conditions and take
appropriate precautions including removing property out of flood-prone areas.
Flooding has been observed in some low-lying areas, and may continue over the next
48 hours. Residents are advised to stay away from all waterways. Banks are extremely
slippery and unstable and when combined with cold moving water pose a serious hazard.
This advisory will remain in effect until February 8. Other updates will be provided
if circumstance warrant.
The Kettle Creek Conservation Authority issues three levels of messages:
- Watershed Conditions Statement: a general notice of weather conditions that could
pose a risk to personal safety or which have the potential to lead to flooding.
There are two variations of these:
- Watershed Conditions Statement – Water Safety: High flows, unsafe banks, melting
ice or other factors could be dangerous for recreational users such as anglers,
canoeists, hikers, children, pets, etc. Flooding is not expected
- Watershed Conditions Statement – Flood Outlook: Early notice of the potential for
flooding based on weather forecasts calling for heavy rain, snow melt, high wind
or other conditions that could lead to high runoff, cause ice jams, lakeshore flooding
- Flood Watch: Flooding is possible in specific watercourses or municipalities. Municipalities,
emergency services and individual landowners in flood-prone areas should prepare.
- Flood Warning: Flooding is imminent or already occurring in specific watercourses
or municipalities. Municipalities and individuals should take action to deal with
flood conditions. This may include road closures and evacuations.
