Hot, dry weather pushes Rideau Valley to a level three low water advisory, with residents urged to cut water use across Ottawa and surrounding towns.
Rideau Valley Declares Level Three Advisory
The Rideau Valley Conservation Authority (RVCA) has issued a level three low water advisory, the most severe category, urging residents and businesses to curb water use. The advisory, announced Tuesday, highlights that the watershed’s water supply is now failing to meet demand due to prolonged hot and dry weather conditions.
Weather Conditions Behind the Shortage
Officials report that rainfall deficits have dropped below 40 per cent of long-term averages, triggering the highest drought classification. This summer alone has seen 22 days with temperatures surpassing 30 C, further straining local streams and reservoirs. According to RVCA, some tributaries have already run completely dry.
Communities Impacted Across the Region
The affected watershed stretches across central Ottawa, Smiths Falls, Perth, and Westport. While Ottawa’s central drinking water system, which sources from the Ottawa River, remains secure, residents in surrounding communities face mounting pressure on groundwater and surface water supplies.
Call for Voluntary Conservation
Although the advisory does not impose legal restrictions, RVCA stresses the importance of voluntary action. “At this point we just want people to be mindful,” said Isabelle Maltais, Director of Watershed Science and Engineering at RVCA. “It’s still voluntary, but we ask people to lower their water use.”
Historical Context of Dry Spells
The current situation is not without precedent. RVCA notes that the watershed has experienced similar dry conditions in 2012 and 2016, when water supplies dropped to critical levels. This year’s extended heat, however, has accelerated impacts more quickly than in previous events.
Next Steps if Conditions Worsen
If the drought intensifies, municipalities may step in with mandatory restrictions on water use. For now, the RVCA urges households and businesses to adopt conservation measures such as reducing lawn watering, limiting vehicle washing, and cutting back on non-essential water consumption.
