Algonquin Park Ice Conditions

|||
All lakes in Algonquin Park remain ice covered. See below for the lastest satellite imagery showing signs that ice out is coming eventually.
Warmer weather conditions and recent heavy rain has reduced snow depth and increased run off. However, the only open water in Algonquin Park is in fast moving rivers, or where inflow and outflow from large rivers has eroded limited amounts of ice.
A Rainfall Warning issued by Environment Canada over Easter Weekend increased water levels in creeks and rivers. Be careful, stay away from fast moving water. Read the latest Flood Forecasting and Warning Program Statement for Pembroke District (including most of Algonquin Park).
Algonquin Park is one of the last areas to shed its ice cover in south-central Ontario. April conditions are extremely important in determining the ice out date for Algonquin Park. Heavy rainfall events, high winds, and warm temperatures all help to speed up ice removal, while cold, snowy conditions can slow the removal of ice from lakes. Watch the Algonquin Park weather forecast for conditions, which are generally colder and snowier than surrounding areas as a result of the Park’s high elevation (the highest in southern Ontario).
This webpage, provided by The Friends of Algonquin Park, tracks the progress and history of ice out in Algonquin Park. Check back frequently for updates.
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. Park visitors are encouraged to stay away from fast moving and icy cold water at this time of year.
Current Conditions at Lake of Two Rivers
Monitor the status of spring by observing conditions at Lake of Two Rivers in Algonquin Park. The image below updates about every 10 minutes during daylight hours, just refresh your browser. Lake of Two Rivers is representative of conditions on medium sized lakes in Algonquin Park. This image is brought to you by The Friends of Algonquin Park, in cooperation with Killarney Lodge. For a record of changes see recent images below.
Lake of Two Rivers is a medium sized lake located in south central Algonquin Park. Lake of Two Rivers entire lake surface, covering 315 hectares (780 acres), is easily observed from Highway 60 allowing for detailed freeze and thaw data to be recorded over the years. On average, Lake of Two Rivers freezes on December 11 and thaws on April 25. Ice out dates can vary widely and in the past 45+ years, ice out on Lake of Two Rivers has ranged from as early as March 30 (2012) to as late as May 10 (2018). On average Lake of Two Rivers sheds its ice cover 3 days earlier than Lake Opeongo, Algonquin Park's largest lake, and the basis for declaring Algonquin Park's ice out (see below for historical ice out information).
Current Snow Depth in Algonquin Park
The snow depth recorded by Environment Canada at Algonquin Park's East Gate over the last 2 weeks. During the early spring, snow depth in Algonquin Park varies greatly depending upon location. On south facing slopes that receive the strongest spring sunshine the ground can be bare, while on shaded north facing slopes snow depths can exceed the values listed below. Deep snow on lakes slows the melting of ice and lengthens the duration of ice cover remaining.
Snow remains on the ground in Algonquin Park despite the appearance of no snow depth below. Environment Canada's weather station at the East Gate of Algonquin Park is currently offline.

Latest Satellite Imagery - Spring 2026
Below is satellite imagery of the Algonquin Park area. Imagery is taken on a regular basis with the best images recorded when cloud cover is minimal, which can be infrequent during late winter/spring. Clear images are posted to highlight the overall changes in ice conditions in south-central Ontario. Ice showing white is the strongest, ice with shades of gray is of decreasing quality, while waterbodies showing black are open.
Image: Satellite image of the White Partridge Lake area of Algonquin Park on April 7, 2026. White Partridge Lake receives minimal inflow or outflow from rivers and thus shows completely ice covered conditions, typical of most Algonquin Park lakes on this date (click to enlarge).
Image: Satellite image of Lake Travers in Algonquin Park on April 7, 2026. Strong water flow from the Petawawa River is slowly eroding ice at inflow and outflow areas of Lake Travers. Some mid-lake locations with restrictions are also showing thinning ice conditions. Lake Travers is one of the first lakes in Algonquin Park to shed its ice cover as a result of the strong current from the Petawawa River.
Algonquin Park Ice Out History
For 60+ years, the average ice out date for Lake Opeongo, Algonquin's largest lake, is April 27. Given variations in winter and spring conditions, the ice out dates for Lake Opeongo have ranged from March 29 (2012) to as late as May 15 (1972). Technically, the official ice out date for Algonquin Park is recorded when a boat can safely navigate from the Lake Opeongo Access Point to the Happy Isle Portage in the North Arm of Lake Opeongo. On average, Lake Opeongo sheds its ice cover 3 days later than Lake of Two Rivers shown above.
2025 Lake of Two Rivers Time-Lapse
The four week time-lapse (below) documents ice out at Lake of Two Rivers using more than 3,220 images. This time-lapse from March 26 to April 27, 2025 is brought to you by The Friends of Algonquin Park, in partnership with Killarney Lodge. Lake of Two Rivers became ice free on April 26, 2025. This date is one day later than the average ice out date observed over the last 45+ years.
Spring and Safety
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. Park visitors are encouraged to stay away from fast moving and icy cold water at this time of year.
Water temperature in spring remains just above freezing for many days after ice out. Submersion in cold water can quickly lead to hypothermia (a potentially deadly situation). Reduce the risks, by wearing a PFD, stay close to shore, paddle according to your skill/experience level, pack the proper safety gear, and don't take unnecessary risks.
Cold Water Paddling
Even though Algonquin Park lakes will become ice free, water temperature during spring remains just above freezing for many days after ice out. Submersion in icy cold water can quickly lead to severe hypothermia, a potentially deadly situation. Reduce the risks by:
- wearing a PFD (personal flotation device) while on the water;
- staying close to shore;
- paddling according to your skill/experience level and the weather conditions;
- packing the proper safety gear; and
- not taking unnecessary risks.
- Learning more about hypothermia and cold water before you paddle.
