No drought here, says RRCA

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.
