The Cataraqui Region Conservation Authority (CRCA) has issued a Watershed Conditions Statement – Water Safety today.
The warmer temperatures and rainfall forecast for Thursday and Friday this week is expected to cause increased flows and water levels on creeks and inland lakes.
Forecasts vary on the expected precipitation amounts, but it looks like periods of rain Thursday and rain changing to snow on Friday as temperatures drop considerably, back down to the minus 10⁰C range.
Widespread flooding is NOT expected. However, weaker ice conditions in the Cataraqui Region can be expected. The break-up of creek ice associated with the warmer temps and changing water levels could potentially block culverts, causing localized drainage issues. In urban areas, catchbasins and storm drains that may be covered by snow, should be cleared to reduce urban ponding.

The CRCA is urging residents to exercise caution around lakes and streams, stay off the ice, away from unstable creek banks, as well as any dams and outflow channels. Stream banks and lake shores may be slippery, increasing the chance of falling in. 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 waterbody.
CRCA staff will continue to monitor conditions and forecasts, and will update statements as needed. This Watershed Conditions Statement will remain in effect until Thursday, January 25, 2018.
