Watershed Conditions Statements
January 21, 2019 — The current very cold weather and large snow storm yesterday is creating some localized ice jams which can cause significant fluctuations in water levels as ice builds and releases. More specifically, the RVCA has received reports of ice jams in the Tay River at Port Elmsley which is causing flooding of some residential properties. There may be other areas as well where ice jams have formed and are causing localized flooding, especially along the Tay River. Since ice jams can form anywhere that there is open water, it is difficult to predict where or when they can…

“Normal” Water Levels in Rideau River Watershed
December 5, 2018 – This statement is to advise that the low water status in the Rideau River watershed is returned to “Normal” including the Kemptville Creek sub-watershed. Precipitation over the last month has brought stream flows up to historical averages throughout the Rideau watershed. Runoff from the rain and snowmelt caused levels to rise late in November. The impacts of low flows experienced throughout 2018, particularly in the Kemptville Creek subwatershed, will not be known until next spring. With inflows well below normal, fish and other inhabitants of the creek struggled to survive in the intermittent ponds left by the…

September 27, 2018 – This statement is to advise that the low water status in the Rideau River watershed has returned to “Normal” except for the Kemptville Creek subwatershed which is at “Minor” Severity, down from “Moderate” Severity.

The exception is at the Environment Canada site in Kemptville which has a 90 day total at 67% of normal, well below…

Low Water Status Continued in Rideau River Watershed
August 30, 2018 – This statement is to advise that the low water status in the Rideau River watershed remains at “Minor” Severity except for the Kemptville Creek sub-watershed which continues to be “Moderate” Severity. Flow in Kemptville Creek has continued to be very low. The amount of rain measured in the Kemptville Creek sub-watershed for the same time period is well below the historical average at both Kemptville and at the Brockville Airport near the Creek headwaters The impact of the low flow is that aquatic creatures living in the Creek are confined to smaller and smaller pools that…
