Potential for High Water

St. ThomasKettle Creek Conservation Authority (KCCA) is warning residents of the potential for high water in the Kettle Creek watershed this evening.

The Ministry of Natural Resources has issued a Provincial Flood Watch for Southern Ontario based on the following information:

A surface low will travel into Southwestern Ontario today bringing general rainfall amounts of 5-30mm, with the higher amounts closer to the Lower Great Lakes Shorelines.

Starting late this afternoon and into this evening a train of thunderstorm activity along the 401 corridor could see a possibility for localized torrential downpours over 50mm in a 4-6 hour duration. As temperatures increase and rainfall continues, the snow pack present across the watershed will melt and contribute to increasing water levels in local creeks and watercourses.

Given the forecast for severe thunderstorms to develop and high intensity, short duration downpours, there is potential for localized flooding to occur.

Kettle Creek Conservation Authority staff will closely monitor local conditions and provide updates as warranted. KCCA staff would also like to remind watershed residents to keep away from the high, fast flowing water and that stream banks can be unstable and slippery. KCCA also advises residents that ice conditions are not suitable for skating, ice fishing or other recreational activities.

The Kettle Creek Conservation Authority issues three levels of messages:

Watershed Conditions Statement (Previously High Water Safety Bulletin): 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 or erosion.
Flood Watch (Previously Flood Advisory): Flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individual landowners in flood-prone areas should prepare.
Flood Warning (No change): 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.
