Where to get out?

I am currently at my moms place here in bremgarten and I went down to the reuss at this spot on the photo. I saw a lot of people started to swim downstream. But where can you get out? I would also be interested to do that downstream swim but dont want to start without knowing where to get out. I am a good swimmer and I also so a lot of elderly people going down so I dont think its that dangerous but any information is welcome
