Jose,
In the northern reaches of San Francisco Bay there are rivers
flowing in from the the interior of California. Ships go all the way
to Sacrameto and Stockton. Power lines cross these waterways.

On either side of the rivers there are much higher than normal power lines
(200') needed to hold the power lines above the ships sailing
up/down river. They vary in height lbut in excess of 600' is not unusual.
These power lines love to eat low flying aircraft.

Therefore flying close along the shorlines or even along the river
can be relatively dangerous.

Never fly along the shoreline of a river used by large ships.
600' towers live there.

What towers are these? Are you referring to the masts? (Even the
original Queen Mary is only three hundred and something)

Or are you referring to the supports for wires and bridges to cross the
river high enough to let the ship pass?
