Notice: Watershed Conditions Statement - Water Safety

Rideau Valley Conservation Authority - February 16, 2018 –  Significant rainfall forecast for Monday and Tuesday along with melting snow can be expected to cause river flows and lake levels to rise.

Going on iced over waterbodies is not advisable for the next several days until levels decline and colder temperatures can restore the integrity of the ice. As the snowmelt and rain runoff moves through the Rideau system, the ice cover can be expected to shift and, in some places, break up. This could lead to ice jamming at culverts and bridges which could cause localized flooding. Ponding water on the surface will make walking on the ice treacherous.

Parents should ensure that children understand the hazards of playing around watercourses in the winter and all watershed residents are advised to stay off of the ice on rivers and streams and avoid icy and snow covered streambanks where footing can be unpredictable. 

Conservation Authority staff will continue to monitor conditions and issue further statements as conditions warrant.

In addition, above freezing temperatures are forecasted starting Sunday, February 18th.

Environmental Conditions: Water levels across the jurisdiction are at normal conditions. The amount of snow on the landscape is normal for this time of year in most areas.

Risks:The forecasted precipitation and associated snowmelt are likely to produce high water levels and possible nuisance flooding.

ACTION: Residents are advised to exercise caution when near rivers as the forecasted weather may rapidly increase river flows and cause slippery river banks. Parents are encouraged to explain these dangers to their children.

Duration: This statement is in effect until Friday, February 23rd, 2018.

SNC monitors the water levels and weather forecasts as part of the Flood Forecasting and Warning Program. Updates are provided as conditions change.
