At the lowest level rescuers may enter the water on foot to rescue casualties and lead them to safety, obviously this will depend on conditions, ankle deep fast moving water can knock you off your feet.
Next up are unpowered craft, including small boats rowed or paddled in and inflatable rescue sleds or pathways. Again it will depend on the speed of the water.
Powered boats can overcome the energy of the water but require specialist vessels which are toughened against the impacts they take from submerged debris. They also need very experienced and skilled operators.
Rescuers may make swim rescues, usually tethered to safety lines, but this is dangerous particularly in swift moving water. Not only is there the obvious risk of drowning but flood water contains a variety of other dangers from debris (floating cars, trees etc) and waterborne diseases, floodwater often contains untreated sewage, chemicals, dead animals etc.
