The short answer is no you cannot. There are no signs anywhere saying this but it is a river with a moving current. There are many underwater obstructions not to mention people's fishing lines and hooks that someone could get entangled in. Is not a safe place to be getting in the water especially for kids
I personally have no interest in swimming, but I'm gonna say there's not a whole lot saying you can't. But I've also seen a video on YouTube off someone encountering a snake in the water. So use your own judgement.
