Lack of Rain Brings Minor Drought Conditions

With no rain over the last ten days and less than 30% of normal for the last 30 days, the Rideau River watershed is on the verge of minor drought conditions.

Precipitation measured at Environment Canada climate stations in and around the watershed show that about 80% of normal for the time of year has fallen in the last 90 days. This means that minor drought status has been reached. Municipal watering restrictions could be imposed to limit the volume of water extracted from groundwater and surface water sources. It is recommended that those living in residences served by private systems also reduce their water taking.

Some rain is forecast for the end of the week and through the weekend but the amount presently estimated is unlikely to be sufficient to do more than slow the decline of water levels throughout the watershed.

Streamflows in unregulated watercourses are about half of normal for the time of year and lake levels are declining. The Rideau Canal system is at full navigation level but, if drought conditions deepen, boaters on all lakes will need to keep an eye open for shoals and rocks as levels continue to drop.

RVCA will monitor conditions and will issue further statements as warranted.
