I was wondering if you anyone had a general sense of water levels in northern Saskatchewan this summer? Whether things are higher or lower than an average year.

It seems like Manitoba/Ontario have been through a hot spell, and that Alberta/BC have got lots of rain, and that the lower Saskatchewan has had flooding. I found a high water report for La Ronge online. Just can't find good info on the area I'm actually going.

The fond du lac river is my curiousity, Wollaston, Black Lake area. So if anyone has a good sense of whether I should expect lower/higher or an average August flow, that would be great to know!

Thanks,
j.

You should be able to find a lot of what you need here: http://www.wateroffice.ec.gc.ca

Hi Bryan,
Thanks for the info, I had gone to that site earlier but had just got confused. Regarding the above graph, which of those lines should I be most interested in? I'm hoping it's not the lower thicker one, cause that is pretty low. The usual yearly August average is about 360 cu/m sec from what I've read.

Also has anyone done the Fond du Lac in a low water year? Just curious if it could still be a good trip or if I should consider something else. I'm guessing it means more lining.

Yes, that web site is a bit confusing and it can take a while to find the useful information if you don't know what to look for.

Yup, it's the lower, thicker, one (discharge = the amount of water flowing in cubic metres per second). It looks thicker in the graph shown because it's zig zagging up and down a bit every day. If you zoomed in on it (looking at a narrower date range, for instance), you would see that more clearly. The upper and lower quartile lines shown give an idea of the "normal" range of water flow. 50% of the time, the flow is between those lines on that date. The lower quartile line shows

There is a drop down box near the top that allows you to choose "discharge" rather than water level (you can also choose water temperature as a secondary parameter if you want). With that selected you can also select the other values down below to put that level in perspective.

Cheers,
Bryan

Here's a screen shot which shows the graph I see, as well as the various settings I have used to get there. After making my selections I click "Redraw" on the right side (either of the 2 buttons - they should do the same I think).

From this graph, on which I've included the minimum, the Fond Du Lac is at record lows and is redefining the minimum.

Hi Bryan, thanks a ton for posting the screen snaps and explaining the chart works. I really appreciate the help.
Hmmmm, okay so I gues I'll have some thinking to do about the choice of river this summer...
Thanks again.
