Even if the university "condones" the behavior, it was still likely negligent on your daughter's part to wade barefoot in a fountain, since there could be any number of things in there (rocks; broken bottles; etc.) that would injure her. The fact that it is negligent to have done this will at the minimum reduce what she might otherwise have been able to recover, since a plaintiff's (the person suing) own negligence proportionately reduces what she can recover. In addition, she could be viewed as having "assumed" (or accepted) the risk of injury by wading in a fountain, and this, too, can reduce or eliminate what she could recover. For these reasons, your daughter is unlikely to recover the full value of her injuries, and it's debatable whether it would be worth the cost and trouble of a lawsuit. That's not to say that she should not ask for compensation, since the school may elect to pay something; but if they refuse to pay, or don't want to pay as much as she or you want, you should think carefully about whether it's worth suing over an activity which, condoned or not, has certain risks and which your daughter voluntarily did.
