The trip was meant to be for investigating water quality, but it soon became a day of fun by the river - several students were sunbathing, at least two were swimming, some were throwing water around and I was swimming/freediving. I did get the work done (measuring the flow rate and describing the surrounding environment), so I didn't get into trouble.

When I first started wading around, it was so cold that it hurt to keep my feet in the water. Soon I got used to it, and it didn't seem that bad! For some reason I find it much worse to get into cold water indoors than outdoors. Getting into a 27C pool is still quite bad. Maybe it is because it was a hot day and in direct sunlight, so it is easier to keep warm.
I was only holding my breath for about 10 seconds max, so it was hard to tell if it had an effect on my dive response. It was extremely difficult to hold my breath, but I was not shivering while I was in the water. When I got out, I started shivering, but still not as badly as after swimming in a cold pool. I guess this could be caused by the dive response - the shivering stops during apnea to conserve O2, then it starts afterwards.
The location was similar to this...
