It's that time of year again – the TSW begins its annual draw down of the lakes. Parks Canada has kindly agreed to provide CEWF with their two-week forecasts of the reservoir lake levels. These will be updated weekly, and published on this site. Stay informed – be prepared.
Here is the forecast for July 26 – August 9:

Hints for reading the forecast:
- To see the amount that your lake level is forecast to change through the two-week period, simply look at the 'Target Differential' columns – shown, for each lake, is the number of metres or inches by which the lake is forecast to change over the two weeks (a negative number is a drop in level, a positive number is an increase).
- If you wish further information, the other columns:
- 'Full Level' is a reference point, indicating the height of the water above the dam sill level* (in metres/inches), when the lake is considered 'full'.
- 'Start Date' shows the measured height of the water above the dam sill level* on that date (in metres), and how many inches that level is down from the full level reference.
- 'End Date' shows the forecast height of the water above the dam sill level* on that date (in metres), and how many inches that level is down from the full level reference.
* dam sill level – the base level of a dam, with all logs removed.
