The Cataraqui Region Conservation Authority (CRCA) has issued a Watershed
Conditions – Water Safety Statement today.
Current forecasts are saying 70 to 90 mm of total precipitation could fall in the region from
Thursday, April 12 through Monday, April 16. Although there is some uncertainty as to amounts
and types of precipitation over this period of time, Environment Canada has issued an alert for
areas in the Cataraqui Region warning of a potential ice storm on Saturday and Sunday. Ice
accumulation could exceed 20 mm.
Localized ponding and flooding of low-lying areas could occur although widespread general
flooding is NOT predicted. The anticipated precipitation could increase water levels and flow rates
in creeks and inland lakes, which are currently at or just above average levels for the time of year.
In urban areas, catch basins and storm drains may be covered with debris or ice accumulation
from the ice storm, and should be cleared to reduce urban ponding.
In preparation for the predicted weather, water managers have been increasing flows through
dams to add storage capacity in the water systems. Dam operations are on-going and will
continue through the week, resulting in increased flows downstream of the structures.
CRCA is urging residents to exercise caution around lakes and streams, stay off any remaining
ice, and to stay away from unstable or slippery creek banks and shorelines, as well as any dams
and outflow channels.
CRCA does not measure ice thickness for advising the public about ice conditions for recreational
activities. Ice conditions can vary considerably from one waterbody to the next and within a single
Winds from the south-southwest are also in the forecast for Thursday, April 12. This could
moderately increase water levels along the Lake Ontario shoreline, along with wave action and
the risk of shoreline erosion.
CRCA staff will continue to monitor conditions and forecasts, and will update statements as
needed. This Watershed Conditions Statement will remain in effect until Friday, April 20, 2018.
Newsrooms please note: A watershed conditions statement is NOT a flood warning. Its purpose
is to raise public awareness about a change or potential change in watershed conditions. See
below for watershed conditions terminology:
Watershed Conditions Statement: 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
• 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: Flooding is possible in specific watercourse 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.
