A thick layer of ice cover remained on Lake Winnipeg and .Lake Winnipegosis in mid-March 2025. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this true-color image of the major lakes of Manitoba, Canada on April 12. Manitoba, a province that is dotted with about 100,000 lakes, is found in central Canada.
Lake Winnipeg, which stretches across the eastern section of the image, is the tenth-largest freshwater lake in the world. It’s also a popular recreational fishery, with a vigorous ice-fishing season that, for many anglers, focuses on trophy-sized walleye. According to The Lake Winnipeg Report, a Facebook page that discusses conditions on the lake, by April 10, warming air temperatures appeared to be taking a toll on the ice cover. Ice thickness was reported at 40 inches (101 cm) and solid across most of the lake the previous week, but the mid-April discussions focused on safety as ice began to thin. One video showed an icehouse being towed off the lake with the caption, “That’s all folks! All ready for next winter.”
In this image, there are only subtle changes in the color of the ice on Lake Winnipeg that appear to suggest the possibility of thinning, such as a light gray tint on the southern basin. To the west, however, the ice on several smaller lakes, including Lake Manitoba, carries the distinct light blue hue of water-logged ice. North of Lake Manitoba, the ice on the long, thin Lake Winnipegosis and the far northern basin on Lake Winnipeg is bright white, suggesting it remains solid.
