News from: April 2018

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.

April 11, 2018 – A weather system out of the mid-west U.S. has the potential to bring several forms of precipitation in significant amounts in to eastern Canada over the next week.

Snow, rain and freezing rain may fall beginning tonight with showers or flurries. Tomorrow, rain is forecast to fall through the afternoon. Rain is expected to begin again late on Friday morning and continue into Saturday, changing to snow in the early morning finishing with as much as 20 centimetres. Rain is presently expected to resume on Sunday and continue into Monday.

If the full amount of forecast precipitation falls, there is the potential for minor flooding to occur in the Long Reach of the Rideau near Kemptville. The lower lying communities in that area may have access issues.

Water levels throughout the watershed are below average for the time of year so there is capacity to accommodate some of the runoff with little impact. Cooler than normal temperatures are forecast which could mean that the runoff process will be slowed to an extent with freezing temperatures overnight. Temperatures closer to spring-like are not expected until the end of next week.

This weather system has the potential to develop into a more significant event over the next five days. RVCA staff will continue to monitor and further statements will be issued if conditions warrant.

April 3, 2018 – Rain in the order of 20 millimetres is forecast for today and into the night that will cause water levels throughout the Rideau valley to increase beyond levels reached after rain on Saturday.

How much levels increase will be limited by dropping temperatures and the changeover from rain to freezing rain or snow overnight and tomorrow. Peak flows from this weather are still expected to be less than average for the spring freshet. These may not be the actual freshet maximum flows.

The Long Reach of the Rideau River, between Manotick and Kemptville, could have levels over the banks as a result of the rain but access is not expected to become a problem in the small river side communities such as Hilly Lane and Cedar Beach.

Rideau Valley Conservation Authority (RVCA) reminds the public to exercise extreme caution around all water bodies. Banks adjacent to rivers and creeks are very slippery at this time and, when combined with current weather conditions, pose a serious hazard. Parents are encouraged to keep their children and pets away from all watercourses and off frozen water bodies, which have been weakened as a result of the warming conditions.

 RVCA will continue to monitor conditions and will issue further statements when or if there is an indication that the situation can be expected to change significantly.
