No drought here, says RRCA
BY STEVEN WARBURTON
Staff Despite Glengarry’s hot and fairly dry summer, the county is not experiencing a drought – at least as far as the Raisin Region Conservation Authority (RRCA) is concerned.
“We’re not at drought level because we’ve had enough precipitation over the past three months,” says Phil Barnes, Project Manager for the RRCA, adding that the precipitation rate was between 87 to 100 per cent of normal and that the RRCA only starts considering a drought possibility when it falls below 80.
Rather than falling regularly and lightly, 2019 saw heavier levels of precipitation that fell less frequently. All in all, the area saw 257.1 mm of precipitation over that period. Normal is 258 mm.
But Mr. Barnes points out that precipitation isn’t the only indicator the RRCA uses to tract droughts. The authority also monitors stream flow levels. And while Mr. Barnes says that most of the watershed’s streams are in the normal range, some are in the lower range of normal.
One of those steams is the Rigaud River, which has a normal flow rate between .2 and 1.7 cubic metres per second. As of Aug. 7, that rate was right at .2.
The Raisin River, which has a normal flow rate of between .1 and .7, currently has a flow rate of .15.
