We also conduct a number of extensive water quantity monitoring activities. As shown in slides 10 and 12, we have about 2,800 sites that measure water levels and stream flow. About half of those provide data in real time. The indicator on slide 10 refers to water quantity in terms of normal, which is a reflection—and I'll let Geneviève provide more detail, if you're interested—essentially, as I understand it, of average flows between 1981 and 2010. In other words, if there's a significant variation, then we would describe it as low, or if it's higher, then it's high. So there's no standard that you look for; it's more looking to see whether there is a big change.
I've referred to the boards that we operate in conjunction with the provinces and the United States—the provinces through MOUs, and the United States through the Boundary Waters Treaty, which is the foundation statute for the International Joint Commission. The IJC boards are illustrated on slide 15, and we can provide more detail on those, if you're interested.
The final point I'll make is the one on slide 17, that all of this work is underpinned by an extensive research program that is undertaken at Environment Canada but also undertaken collaboratively with the academic community and with provinces and territories and with colleagues in the United States.
