In Lake Texoma, near the Texas Oklahoma border, Army corp of engineers have discovered a 8 foot wide spinning vortex in the lake.
The vortex is especially dramatic Â because of the deluge of rain the region has received over the past few weeks, which has caused massive flooding. Lake Texomaâ€™s waters reached a record-high elevation a few weeks ago of nearly 646 feet above sea level.
A whirlpool is a swirling body of water produced by the meeting of opposing currents. The vast majority of whirlpools are not very powerful. More powerful ones may be termed maelstroms. Vortex is the proper term for any whirlpool that has a downdraft.
Whirlpools in oceans are usually caused by tides. Very small whirlpools can easily be seen when a bath or a sink is draining, but these are produced in a very different manner from those in nature. Smaller whirlpools also appear at the base of many waterfalls.
The most powerful whirlpools are created in narrow, shallow straits with fast flowing water.
One of the largest reservoirs in the US, Lake Texoma lies on the border of Oklahoma and Texas and is formed by the buildup of water at Denison Dam on the Red River.

When the water levels get too high, as they have in recent weeks, the Army Corps opens sluices, called floodgates, at the bottom of the lake to drain the water into the river. The flowing water creates cyclonic action, muchÂ like a tornado, which is widest at the top and tapers down at its tip.
