Our system will evaluate the answer based on this AI-generated description.
The image is a diagram titled "Hydroelectric power station" depicting day and night operations. On the upper left, a "River" flows into a "High-level reservoir" retained by a "Dam". Water connects via a pipeline labeled with an "Intake (Day: open, Night: closed)", "Night: pump water into high-level reservoir", "Flow of water to generate electricity (day)", and "Flow of water during pumping (night)". The pipeline leads to "Reversible turbines" inside the "Power station" structure, which connects upward via a shaft labeled "Day: operate generator" to a "Generator". The generator connects to "Power lines" that lead to the "National grid". Downstream from the turbines, water flows to and from a "Low-level reservoir" marked with two water levels: "(Day)" at a higher level and "(Night)" at a lower level.
Given the complexity of the image, the above description may not be entirely accurate.

The picture illustrates how an electricity was made by a hydroelectric power plant.
Overall, this is a multi-staged process of hydroelectric power station producing electricity, beginning with pumping the water from the river and ending with generating electricity. The power station is open during the day, while at night it reduces its work and stays closed.
To produce an electricity, firstly the river is needed to be moved into a dam as a high-level reservoir during the daylight, as the water gets pumped into high-level resevoir when the night comes. The water gets transported towards the reversible turbines of power station through two high-level reservoirs, one meant for a day which is located above, and the other for the night, that is below the daylight high-level reservoir.
The water from reversible turbines move to the generator before moving through power lines. However, at night, the reversible turbines send water towards low-level reservior.
