Lake is drained - level 2
Lake Texoma is one of the largest man-made lakes in the United States. It lies on the border between Texas and Oklahoma. People use it to control floods, control river flows and make power. Something interesting happened on the lake – something formed a vortex.
The vortex was approximately 2.4 metres across, so it could not suck in a full-sized boat.
Someone filmed the vortex and it looked pretty cool. The lake was being drained like a bathtub!
Difficult words: vortex (a mass of water that spins quickly and pulls things into its centre), approximately (around), drain (to make water run out).
