water safety

January 9, 2020

Cataraqui Region Conservation Authority has issued a Watershed Conditions
Statement – Water Safety today due to a strong storm system that is forecasted for January 10 through 12 and expected to bring rain and freezing rain to the region. Total amounts and form of precipitation is uncertain, but forecasts are calling for rainfall amounts of 25-55 mm+. Higher amounts are possible.

With frozen ground conditions and minimal snow pack to absorb rainfall, high runoff into lakes and streams is expected, followed by water level and flow increases.

As a result of recent rainfall events, Water Managers, who operate dams on area lakes, are passing above average flows through water control structures to keep water levels within targets for this time of year. These flows are being further increased to prepare for and mitigate, as much as possible, the impacts from this significant rainfall event. Water levels on inland lakes and streams may rise for several days.

The Cataraqui Region Conservation Authority is urging caution around all dams (inflow and outflow channels) and fast flowing watercourses. Respect the hazards in these areas by obeying all warning signs, keeping away from booms, buoys, and barriers. Stay well back from the water’s edge above and below dams and hydroelectric stations. Creek banks and lake shorelines may be slippery, increasing the chance of falling in.

Also, due to the high flows, ice formation on lakes can be very unsafe. The Cataraqui Region Conservation Authority does not measure ice thickness for advising the public about ice conditions for recreational activities. Ice conditions can vary considerably from one waterbody to the next and within a single waterbody.

Widespread flooding is NOT expected at this time. However, localized inundation of low-lying areas is likely. If you witness flooding and/or require assistance your first point of contact is the local municipality.

Staff will continue to monitor conditions and forecasts and will update statements as needed. This Watershed Conditions Statement will remain in effect until (or updated before) Wednesday, January 22, 2020 at 11:59 PM.

See below for watershed conditions terminology:

Normal: No flood conditions exist

Watershed Conditions Statement – Water Safety: High flows, unsafe 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.

Watershed Conditions Statement – Flood Outlook: Early notice of the potential for flooding based on weather forecasts calling for heavy rain, snow melt, high wind or other conditions that could lead to high runoff, cause ice jams, lakeshore flooding or erosion.

Flood Watch: Flooding is possible in specific watercourse or municipalities. Municipalities, emergency services and individual landowners in flood-prone areas should prepare.

Flood Warning: Flooding is imminent or already occurring in specific watercourses or municipalities. Municipalities and individuals should take action to deal with flood conditions. This may include road closures and evacuations.
