Elephants (almost) drowning while crossing the River

a Herd of elephants (almost) drowned while crossing the Sabie River, Kruger national park after the recent flooding in January 2017.
This was taken during the recent flooding 3 weeks ago. These Elephants tried to cross the Sabie river just north of Lower Sabie. First I thought they were swimming but soon realized the current are sweeping them away. It was nerve wrecking. I tried to keep up but with all the bushes it was not an easy task.
Some elephants on the other side of the river were very unhappy. One of them wanted to cross as well and you can hear her constantly screaming. At one point she tried to cross but turned around. Didn't have the nerve I think. It was sad to see how upset she was. All ended well and the ones I saw all arrived safely.
