narrow concrete channel in Chernushka, Russia, carrying rapidly flowing water

narrow concrete channel in Chernushka, Russia, carrying rapidly flowing water. The channel is lined with a rusty metal safety railing on both sides. Patches of snow remain on the ground adjacent to the channel. Trees are visible on one side, and a body of water is in the distance. The water in the channel is dark with white foam and turbulent flow. The photograph appears to be taken from a slightly elevated perspective, looking down the length of the channel.
