(WCS – R07/2020)

December 24, 2020 — Environment Canada is forecasting between 30 and 50 mm of rain starting today and continuing overnight throughout the Rideau Valley watershed. 

Although no significant flooding is anticipated, water levels and flows are expected to increase in all waterways in the Rideau Valley Watershed. Depending on how much rain falls, residents who are adjacent to the smaller creeks and streams are advised to keep a close watch on water levels and flows and should take the necessary precautions to protect their property, such as:

• Ensuring sump pump is clear, in good working condition and has a backwater valve
• Ensuring easy access to a portable backup generator and pump

With the expected increase in water levels and flows in the coming days, ice cover 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.

This watershed conditions statement is in effect until Monday January 4, 2020 at 5 PM or until an update has been issued.

 RVCA Watershed Conditions Statements:

• Water Safety – High flows, unstable banks, melting ice or other factors that could be dangerous for recreational users such as anglers, canoeists, hikers, children, pets, etc. Flooding is not expected.
• Flood Outlook – Early notice of the potential for flooding based on weather forecasts, calling for heavy rain, snow melt, high winds or other conditions that could lead to high runoff, cause ice jams and/or lakeshore flooding or erosion.
• Flood Watch – Flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individuals in flood prone areas should prepare.
• Flood Warning – Flooding is imminent or already occurring in specific watercourses or municipalities.

WCS – R01/2021)

January 13, 2021 – Environment Canada is forecasting mild temperatures for the remainder of this week, with daily temperatures above zero each day and some rain expected on Friday and Saturday. This follows a warmer than usual December and a mild January to date. As a result of a significant rain event on December 24 and 25, water levels are above normal for this time of year in the some of the lakes and rivers in the Rideau Lakes and Tay Valley sub-watersheds. Generally, water levels are at normal levels for the remainder of the watershed. 

Although no significant flooding is anticipated at this time, it is expected that water levels and flows will continue to fluctuate across the watershed with the continued warmer-than-normal conditions and forecasted rain later this week. As a result, ice thickness can change drastically and be unpredictable. The shoreline adjacent to lakes, rivers and creeks is also very slippery and poses a serious hazard. Falling into open water can result in hypothermia or drowning.

The RVCA reminds the public to exercise extreme caution around all waterbodies by:

• Regularly testing ice thickness and staying off ice that may cover flowing water
• Reminding children about the dangers of playing on or near ice covered surfaces and open water
• Keeping pets on leash near frozen water bodies.

RVCA does not monitor or maintain ice conditions anywhere, including its 11 public conservation areas. This includes the Rideau River and its tributaries, as well as the ponds, lakes and other bodies of water within our parks.

This watershed conditions statement is in effect until Monday, February 1, 2021 at 5 PM or until an update has been issued.

WCS - R02/2021

January 29, 2021 – Environment Canada is forecasting very cold weather beginning today and continuing into Sunday before returning to normal range on Monday. This includes night-time wind chill temperatures in the range of -20 to -30 degrees Celsius. In areas where there is a lack of ice cover along with turbulent flow, these cold temperatures can trigger the formation of frazil ice which can accumulate quickly on bridge abutments, piers and riverbanks resulting in increased water levels and flooding in low-lying areas. The small rivers and streams with open water, such as the Tay River, are considered the most vulnerable for frazil ice formation, resulting in localized flooding. Please notify RVCA if any localized flooding is observed to due frazil ice formation by sending an email to .

Residents are advised to stay away from all rivers and watercourses in the vicinity of any frazil ice and high-water areas. Parents are encouraged to explain these dangers to their children.

This watershed conditions statement is in effect until Monday February 1, 2021 at 5 PM or until an update has been issued.
