I hit a fox in my daily, busted up my bumper badly.... I wanted to take the fox to court but I cant because his lawyer tells me he was pronounced dead at the scene... gutted! (true story bar the last bit)
On a serious note... I hear what you're saying and by all means try and contact a water company if that's who caused the water... However, bare this is mind, The leak may have just happened, were you the only person that lost control of your car and how come others made it through without crashing?
