The MNRF participates in a cost sharing program with Environment Canada to maintain automatic water level monitoring stations on many of the larger lakes in the district. These stations are part of the Real-Time Water Level Network. This information can be accessed for the lakes listed below at http://www.wateroffice.ec.gc.ca/index_e.html.
Click on the link above and obtain the current water level value for the lake you are interested in. You must then add a unique conversion factor to the water level value obtained in order to determine the ACTUAL water level reading (elevation above sea level, in meters) for each lake. Actual water level values can then be compared to the annual lake operating plan chart of interest.
Add the Conversion Factor to the water level value from the Real -Time Water Level Network to determine the actual water level reading for one of the seven lakes listed.
Water Level Monitoring Station
|Fairy Lake (part of Huntsville Lakes Chart)||277.290|
|Go Home Lake near Potters Landing||0.0000|
|Lake Muskoka at Beaumaris||215.950|
|Lake of Bays at Baysville||304.841|
|Lake Rosseau at Port Carling||217.120|
|Mary Lake at Port Sydney||272.066|
A number of smaller lakes are not part of the real-time water level network. The MNR has built partnerships with cottager associations and volunteers to provide water level readings on their lake. These partnerships benefit both the MNR and the shoreline landowners.
