How can the presence of vegetation surrounding a stream cause daily fluctuations in the stream’s water level?

		In cold temperatures, vegetation can physically block the movement of water from the riparian zone to the stream.
		Leaves can clog the streambed and reduce groundwater flow into the stream.
		Vegetation can increase moisture in the air during the day, which can later precipitate and increase the water level.
		Trees can pull water from the stream for photosynthesis, thus lowering the water level during the day.
