rain on water

RELEASE — The Cataraqui Region Conservation Authority (CRCA) has issued a Watershed Conditions Statement – Water Safety today.

Rainfall amounts of 30 – 50 mm are forecasted for Thursday night and Friday across the region, with Kingston and areas to the north expected to receive as much as 45 – 50 mm. Brockville is forecasted to receive 30 – 35 mm.

Environment Canada has issued Rainfall Warnings across southeastern Ontario anticipating that rain will be heavy at times. As a result, it is expected that lake levels and outflows will increase as well as water levels and flows in area watercourses.

Widespread flooding is NOT expected. However, nuisance flooding of localized low-lying areas may occur. Urban areas may experience ponding on roadways and in areas where drainage infrastructure is overwhelmed. Catchbasins and storm drains should be cleared to reduce urban ponding.

Water managers continue to conduct operations to minimize the effects of this rainfall and pass flows down through the systems.

The rising water levels and warmer temperatures are expected to result in weaker ice conditions on area lakes. CRCA staff is urging residents to stay away from fast flowing watercourses, as well as any dams and outflow channels and to exercise caution around lakes, creeks and stay off the ice. Creek banks and lake shorelines 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 Monday, December 24, 2018.
