Watershed Conditions Statements

April 3, 2020 (WCS – R06/2020)  –The Rideau Valley Conservation Authority is terminating the FLOOD WATCH that was previously in effect and issuing a HIGH WATER SAFETY message for all areas. Water levels and flows are still high for most, but not all, of the larger waterbodies in the Rideau Valley Watershed. The short-term forecast does not indicate any significant precipitation and the snow is now melted across the Rideau Valley Watershed. As such, water levels and flows are expected to slowly decline in the days ahead. Everyone needs to be cautious around lakes and streams with the fluctuating water levels.…
March 30, 2020 — A Water Safety Statement is being issued for areas along the Lower Ottawa River. Based on current snow cover and weather forecast, it’s anticipated that levels and flows from Arnprior to Hawkesbury will remain within the normal range of fluctuations associated with the spring freshet period. The Ottawa River Regulating Committee indicates that with warming temperatures and forecasted precipitation, increases in flows and levels are expected to continue and may cause minor flooding in low-lying areas over the coming weeks depending on the temperatures and precipitation received. Levels are currently expected to remain below flood thresholds.…
Updated Flood Outlook & Flood Watch: Rain in Forecast Will Cause Water Levels to Increase Again Across the Rideau Valley Watershed (WCS – R05/2020) March 27, 2020 –The short-term forecast is calling for rainfall amounts of 35 millimetres or more on Sunday and into Monday with above zero temperatures. As such, water levels and flows across the Rideau Valley Watershed are expected to increase again. A FLOOD WATCH is being issued for properties around Christie Lake and Wolfe Lake. In these areas, residents should expect freshet like water levels and flows. Parks Canada staff are closely monitoring the water levels in…
Flood Outlook & Updated Flood Watch - Warm Temperatures and Rain in Forecast Will Cause Water Levels to Increase Across the Rideau Valley Watershed (WCS – R04/2020) March 19 ,2020 – The short-term forecast is calling for rainfall amounts of 10 to 15 mm and high temperatures near 15 degrees Celsius on Friday, followed by below zero temperatures on Saturday, and then milder temperatures in the days following. No significant rain is in the short-term forecast after Friday.  With Friday’s rain and high temperatures, water levels and flows across the Rideau Valley Watershed are expected to increase everywhere and then…
(WCS – NG01/2020) March 10, 2020 – The mild weather yesterday and today has melted a significant amount of snow in the Rideau Valley Watershed.  This snow melt together with some rainfall is causing the water levels to rise quickly in Stevens Creek and Taylor Drain. Based on new water level gauges installed in the spring of 2019, it appears that the water may breach the banks and cause localized flooding within the low-lying areas along Stevens Creek and Taylor Drain in the Village of North Gower. The timing of the potential breach will depend on the temperatures and rainfall…
March 9, 2020 (WCS – R03/2020) — The winter of 2019-20 has been warmer than average with near-average snowfall amounts. On January 11, about 50 mm of rain fell across the Rideau Valley Watershed, resulting in temporarily elevated water levels and flows in all waterways, and a noticeable ice layer within the snowpack. Current conditions at several RVCA and Parks Canada snow course sites are indicating above average water content amounts in the snow for this time of year. The current short-term forecast indicates daytime high temperatures above zero and below zero conditions at night with precipitation expected tomorrow (up to 15…
