Watershed Conditions - Water Safety Statement UPDATED JAN 14, 2020

Record Rain Causes High Water Levels, Fast Flows, and Unstable Ice Throughout Rideau Watershed

January 14, 2020 Rideau Valley Conservation Authority — With high water levels and fast flows all across the Rideau Valley Watershed, the ice cover (where present) on lakes, ditches, local streams and rivers will be unstable. Extreme caution should be exercised by everyone when near local waterbodies. Parents should inform their children of the risks and provide appropriate supervision.

On average, 50mm of rain fell across the Rideau Valley Watershed last Saturday before the temperature dropped to below freezing, resulting in significantly elevated water levels and flows in all waterways. The smaller creeks and waterways were impacted the most with ‘bankfull’ conditions observed in some areas, although the water levels are now stable or receding.

Although the flow in the Rideau River, our largest river, peaked at four times its average flow for this time of year at the Carleton University gauge, the flow increase did not result in any observed ‘bankfull’ conditions along the river. With the exception of tomorrow, the weather forecast is indicating below zero temperatures for the next several days so water levels and flows are expected to decline.

Please note that the RVCA does not monitor ice conditions. The RVCA’s Flood Forecasting and Warning team will continue monitoring weather, snowpack, water level and flow conditions and issue updates as required.

This watershed conditions statement is in effect until Monday January 20, 2020 at 5 PM or until an update has been issued.

Watershed Conditions: Water Safety Statement

January 14, 2020 South Nation Conservation

Weather Forecast:
Temperatures are expected to remain below freezing for most of the week.

Environmental Conditions:
Water levels across the watershed are high for this time of the year. Precipitation gauges across the jurisdiction recorded 40 mm of rain over the weekend.

Risks:
Due to last weekend’s significant rainfall as well as snowmelt, the watershed is experiencing higher than normal water levels.

ACTION:
Residents are advised to exercise caution when near watercourses as flows may rapidly increase and cause slippery or unstable banks. Residents are also advised to stay off all frozen bodies of water. Parents are encouraged to explain these dangers to their children.

Duration:
This statement is in effect until Tuesday, January 21, 2020.

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