ok, let me throw an idea in this... could it be like the rivers at water parks ? where the river flows when the pumps are on. You could maybe use solar power to pump the water from the bottom to the top...only problem might be how much solar you would need to do that on any given day. At night the river/stream would only fill the pools .
