A small, dark-furred mammal, possibly a muskrat or nutria, swims across a calm body of water from left to right. Its head is visible above the waterline, and it leaves a distinct V-shaped wake behind it. The water reflects an overcast sky, creating a muted, silvery surface. The banks of the water are densely covered with lush green vegetation, including tall grasses, weeds, and some plants with small yellow and white flowers. Some darker rock-like structures are visible in the foreground on the bottom right. The scene depicts a peaceful natural setting, likely in Chaikovsky, Russia, during daytime under cloudy conditions.
