Here is the forecast for the lake levels in the Haliburton Region, for the period Aug 31-Sep 14. As this year's draw down gets into full swing, you'll see on the chart quite large changes in lake levels planned – over this 2 week period, the projected lake level changes range from a rise of almost 22 inches on Gull Lake (putting it above its 'full' level by almost 19 inches), to a drop of almost 23 inches on Big Glamour Lake.
