April 29, 2020 - Cataraqui Conservation has issued a Watershed Conditions Statement – Water Safety today in response to a significant weather system crossing the Province.
Expected rainfall amounts are uncertain, but forecasts are calling for 35-75 mm from this event before it wraps up on May 1, 2020. Higher amounts are possible.
A somewhat drier than average April, so far, has resulted in below average creek flows. The forecasted rainfall is expected to cause significant increases to current levels and flows.
Water Managers, who operate dams on inland lakes in the region, are passing high flows through water control structures to keep water levels within targets for this time of year. These flows are being managed to mitigate, as much as possible, the impacts from the expected rainfall. As a result, water levels on inland lakes and streams may rise for several days.
Cataraqui Conservation 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.
Widespread flooding is NOT expected at this time. However, localized inundation of low-lying areas is possible. 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) Thursday, May 7, 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.
