When Jet had Katara and Aang use waterbending to get the water that was unsuccessfully attempting to come out of the steam geysers, the water kept coming out and filling the river that went into the reservoir. I know eventually that the water would have stopped, but this leaves me with 2 questions:
1. Since the geysers' water wouldn't stop coming (at the time) after the pressure was released with bending, wouldn't the dam have eventually been completely filled and started to flood the town anyway by going over the dam's top, even if the dam wasn't blown up and the citizens would have been able to evacuate, since the water most likely would have slowly gone over the top?
2. How soon could the town Gaipan rebuild itself, since the geysers' water was still coming into the river and its reservoir, most likely for quite a while?
