KINGSTON – The Cataraqui Region Conservation Authority (CRCA) has issued a Flood Watch today.
The storm event that occurred October 28th through 30th dropped more than 100 mm of rain in some parts of the CRCA region, including over 50 mm in 12 hours. The resulting impacts (e.g. roadway flooding) and increase to urban creek levels peaked and began receding on October 30th.
Significant increases to creek and lake levels have occurred across the region. Fast-moving water and higher than normal levels remain, and some lake levels continue to rise.
The Surface Water Monitoring Centre of the Ministry of Natural Resources and Forestry issued a Provincial Flood Watch at 11 am today for Southeastern Ontario.
‘Water levels and stream flows in eastern Ontario’ … ‘are elevated from heavy rainfall last weekend. The saturated conditions have reduced the capacity of soils to store additional rainfall. Forecast cumulative rainfall of 50 to 60 mm by Saturday morning has the potential to further elevate water levels, resulting in localized flooding’
Specific to the CRCA region, flooding of low-lying areas associated with the following may occur:
Gananoque System: Brockville:
Upper Beverley Lake Buells/Butlers Creek and the Detention Basin
Lower Beverley Lake Lyn Creek
Singleton Lake Kingston:
Graham Lake Collins Creek
Water managers continue to conduct operations to minimize the effects of the increased water levels and pass flows down through the systems. CRCA staff is urging residents to stay away from deep, fast flowing watercourses, as well as any dams and outflow channels.
Widespread flooding is NOT expected as a result of the coming rainfall, however localized flooding of low-lying areas adjacent to creeks is a possibility.
CRCA staff will continue to monitor conditions, forecasts, and update statements as needed.
This Flood Watch will remain in effect until Friday, November 10, 2017.
