Kettle Creek Conservation Authority
KCCA downgrades to a Water Conditions Statement  Flood Outlook for the Lake Erie Shoreline

August 7, 2019 - This notice is intended to update the public and local municipalities on the high water levels in Lake Erie and the effects on the Kettle Creek Conservation Authority (KCCA) watershed.

Lake Erie water levels, while still at a record high, have dropped to 175.07m which is below KCCA's established threshold for heightened shoreline storm surge monitoring of 175.25m during the boating season.

As of August 5, 2019, Lake Erie's static (calm) water level was 175.07m. This water level is 78cm above average and 10cm above the record-high for this time of year (set in 1986). This level does not account for any increase in water levels due to storm surge or wind driven waves. A decrease in precipitation in July has contributed to the decline in water levels in Lake Erie over the month of July. As of August 5th, water level data indicates that the mean has decreased by another 2cm compared to last week.

"Although water levels are declining, they still remain at record high levels," says Jennifer Dow, KCCA's water conservation supervisor. "That means that there is still a heightened risk for flooding and erosion along the Lake Erie Shoreline due to storm surge. Summer storm events, especially in the Great Lakes region can move in quickly bringing gusty winds and heavy downpours," says Dow. Areas of concern are the low lying beach communities and shoreline areas along Lake Erie, including the low lying areas along the downstream reaches of Kettle Creek within Port Stanley.

The greatest risk for flooding and erosion in the Kettle Creek watershed is in Port Stanley when storms bring sustained Southwest winds. Typically, sustained wind speeds in the range of 50 km/hr or higher are associated with an increased risk of flooding, shoreline erosion, and damage to shoreline structures due to damaging waves and localized flooding.

Residents are reminded to continue to be aware of their local conditions and take appropriate action should conditions change. Under high water and flooding conditions, the combination of slippery banks, waves, waves overtopping shoreline structures, and fast moving water can be dangerous. Standing water can also present its own unseen hazards. Children and pets should be kept away from flowing or standing water as well as shoreline areas.

KCCA staff will continue to monitor Lake Erie conditions and provide updates as warranted. This Watershed Conditions Statement—Flood Outlook will remain in effect until August 31, 2019 at which time conditions will be reevaluated.

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.
