Shadow Lakes Daily Water Levels

If you are interested in finding the specific water level in Shadow Lake, or any other site, at any time you may do so by accessing the following link http://www.wateroffice.ec.gc.ca.

Accept the disclaimer.
Choose My Station List.
The first time you do this, agree to the cookie store so you can easily return to view the same water quantity location next visit.
Choose 'edit list' from Watch List the first time, select province of Ontario, then select and add 'Gull River at Norland' to your list.
You will now see 4 boxes on the right for the water quantity data for Last Month, Last Week, Last Day, and the Current Value.
Clicking on any of these boxes will bring up a graph showing either the Gull River “discharge rate” in cubic meters/sec or you can move from that and select the “primary water level” and redraw the graph.
In either case make sure that the dates you want (underneath) are covered, and if not, change them.
The level is a depth measurement in meters at the river near Norland and can be compared to a mean annual measurement of approx 3.8 meters. So, if for example the reading is 3.3 meters, it is meter or approx. 20 inches below normal.
You can store the link in “favourites” so you can access it easily whenever you want.

Predicting Shadow Lakes Water Level Changes.

There is a relatively simple way, using readily available internet data, to gain some insight as to probable immediate future water level changes on Shadow Lake. The procedure is as follows.
Go to Parks Canada Water Levels for the Trent-Severn Waterway at:

From “Gull River Watershed” list, select “Gull Lake”.
You are now looking at how full the nearest major lake above us is. If high, it cannot absorb much rainfall; if low, it can. You can also check Horseshoe Lake to see how full the next major lake above Gull Lake is.

Go to The Weather Network at www.theweathernetwork.com/weather/caon0438 to see how much rainfall is expected in the next few days.

Now you have it all. With high (say much above 4m) readings at Norland, high water already in the Gull lake system above us and lots of rain in the forecast you can expect rising water in Shadow Lake, and visa versa.
