There is no distance you need to be away from a house when you are on public water and abiding by local shooting laws. There is however, a 500 foot limit near livestock. Also, you can jump shoot on the river if no wider than 100 yards I believe. At 100 yards of river width, you need to be partially concealed by natural vegetation. Further, you can use a motor to move about the river, BUT before you shoot, you must come to a full stop (gray area considering there is current, but your propulsion impact must be mitigated). Further, with a motor, you also cannot travel with a loaded gun. So motor, stop, load gun and then take aim and shoot. Better be a slow bird.
