UPDATE: The Cataraqui Region Conservation Authority (CRCA) has extended the below previously issued Watershed Conditions Statement – Flood Outlook for Millhaven Creek:
Millhaven Creek (map), between Highway 401 and Lennox & Addington County Road 4, is a stretch of creek that is prone to ice jamming. The current conditions and weather forecast suggest an increased risk of ice jam formation and localized flooding.
Currently, the primary location of concern is the low-lying areas in Odessa next to the creek along Gore Street that are already experiencing elevated water levels due to the build-up of ice in the creek and resulting in reduced flow capacity.
The combination of warmer temperatures forecast for next week and rainfall starting Sunday or Monday may increase flow in the creek, increasing the likelihood of further ice jamming and elevated water levels in the localized low-lying area.
Although the potential exists for localized flooding, widespread flooding is NOT expected at this time.
CRCA and Loyalist Township staff are monitoring the situation.
Sandbags and sand will be available at the Loyalist Township sand dome at 748 County Road 6, should residents require them.
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. CRCA staff will continue to monitor conditions and forecasts and will update statements as needed.
UPDATE: This Watershed Conditions Statement will remain in effect until Wednesday, February 27, 2019.
