i've also accidentially fallen in the river a couple of times over the past two years, and i will confirm that the water is safe and getting colder every day this time of year.

I believe for open water swimming, the definition of 'safety' they're aiming for includes checking the water for human faeces and bacteria like e.coli.
A one-in-250 chance of getting diarrhoea the next day is no problem for clumsy drunks, who'll just be glad to make it out - but for a health/fitness event it's undesirable.
In this image from the Chicago Tribune you can see two of the bots. one is orange, the other yellow. they should have been in a straight line since they were being used to guide the swimmers down the course.
i was told they position via gps and their gps just didn't work downtown.
