Thank you, Madam Chair. Can you -- I guess, you've identified some criteria there, but I -- can you expand on that bit because, you know, we talk about, you know, volume of snow; we may have some rain down south; we have cold weather possibly that could impact it; we might have -- you know, you say that with ice we -- you know, it makes it difficult to predict as well but, you know, if it -- it just depends what the weather's like we could have thicker ice. If we don't have a lot of snow, that could cause that as well. We have, you know, in the Hay River for instance, we got the mouth of the river and the -- you know, the channel and that's getting, you know -- I guess basically the silt is increasing, the amount of silt that's in there. Does that have -- you know, what kind of impact does that have. We've got two channels there. We've got the west channel and the east channel. And so I'm just trying to get an idea, you know, what we're looking at when we look at flooding aspects. Thank you.
