Current Conditions in Algonquin Park

Topics Below

The majority of Algonquin Park’s lakes remain ice covered but some lakes with significant inflow and outflow, and those at lower elevations, are open or partially open. Anglers coming to Algonquin Park for the opening of trout fishing season (April 22, 2017) are expected to find limited amounts of open water and unsafe ice conditions. Large lakes are showing many signs of weakening ice, with the majority of large lakes predicted to shed their ice sometime next week (April 24 to 28, 2017). The last lakes to shed their ice are expected to be large lakes with little inflow/outflow at high elevations in Algonquin Park.

ImportantEven though ice may disappear from lakes, snow covered/muddy roads, high water levels, fallen trees, and washed out roads can prevent access to some backcountry access points near the end of April (and possibility into early May). Ontario Parks is reporting that the spring 2017 opening dates for some areas of Algonquin Park will be delayed. High water and flooding from recent rain and spring snow melt has also closed some Algonquin Park facilities. For the latest closures/restrictions see Algonquin Park Advisories.

Live Views of Algonquin ParkSnow depth in Algonquin Park varies greatly depending upon location. On south facing slopes that receive the strongest spring sunshine, snow has all but disappeared with bare ground conditions. Shaded north facing slopes have snow depths that currently exceed calf-deep (more than 20 centimetres or 8”) in some locations. Overall most ground in Algonquin Park is nearly bare.

Watch this webpage for updates and new images as conditions warrant. For live views of Algonquin Park see the Algonquin Park Webcam providing live streaming video.

Please remember that The Friends of Algonquin Park advises against ice travel due to a range of environmental variables and the difficulty in detecting hazards. Be safe, stay off the ice.
