A new organization has formed to try to get our water levels managed in a more consistent and equitable manner. Click here to view their website, which has information on their aims and activities.

NEW INFORMATION FOR JUNE 2010.
Parks Canada has released this communication regarding the situation with Shadow Lake water levels. Since this is effectively a snapshot of where we are right now the value of this document will have a very short shelf life. We also have confirmation from the new superintendent for a meeting within the next 2 weeks to pursue the issue of a minimum flow commitment and reduction in lake level volatility. We will advise as to progress.

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 at
 www.pc.gc.ca/lhn-nhs/on/trentsevern
Select water levels on the right below the graph
Select “Gull River Watershed”
Select “Gull River – second red dot from the bottom”
Accept conditions
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 forecasted you can expect rising water in Shadow and visa versa.

We don’t seem to be able to directly affect changing water levels in our lake but we can  try to be prepared for it.
