April 18, 2018 – The snow and ice accumulation over the last several days raises the possibility of flooding in parts of the Rideau system as warmer conditions arrive on Friday.
Rain and some melting has caused streamflows to increase throughout the watershed. Daytime temperatures above 10 degrees through the coming weekend and into next week can be expected to melt the remaining snow and ice. There is the potential for this meltwater to cause access issues in the low-lying communities on the Long Reach of the Rideau between Kars and Kemptville. Tributary streams such as Stevens and Cranberry Creeks in the North Gower area can be expected to overtop their banks.
The next occurrence of precipitation is not expected until next Wednesday when 20 to 30 millimetres could fall. Such rain is expected to prolong but not worsen the situation.
With water levels elevated and standing water in ditches and fields, the Rideau Valley Conservation Authority (RVCA) reminds the public to exercise extreme caution around all water bodies. Streambanks are slippery and any remaining ice cover on streams, ponds and lakes will be hazardous. Parents are advised to keep their children and pets away from all watercourses as levels fluctuate with the spring weather.
