Wolfe Lake water levels slowly and sometimes drastically decrease throughout the summer and fall. These decreases are due to a combination of evaporation and the release of water to maintain navigable water levels on the Rideau Canal. Water is released through the dam located on the southeastern shore of Wolfe Lake. At the nearby boat launch automated equipment measures and transmits water level data to a central site.
Present water levels are measured weekly and can be obtained through the Internet at: Wolfe Lake Water Levels under the title ‘Water Level Stations’ when the date is available.
