ZOCs over rivers?

Zone-of-Control

The six hexagons immediately surrounding an occupied hex make up that unit’s Zone of Control (ZOC). Zones of Control affect the movement and supply of the other side. When a unit enters an enemy Zone of Control it may be fired upon. The cost to move from a hex that is an enemy Zone of Control to another hex that is also an enemy Zone Of Control will be greater than normal and could be prohibited if the Optional Rule, Locking Zones-of-Control is in use. Refer to the Main Program Help File.

There are a few units which do not exert a Zone-of-Control:
• HQ units do not exert a Zone-of-Control.
• Supply units do not exert a Zone-of-Control.
• Broken units do not exert a Zone-of-Control.
• Towed Anti-Tank units do not exert a Zone-of-Control.
• Towed Heavy AA units do not exert a Zone-of-Control.
• Units which have a Facing do not exert a Zone-of-Control in the hexes they are not facing.
• Partisan and Irregular units do not exert a Zone-of-Control.
Commando, Irregular and Partisan units have the ability to move from one enemy ZOC to another.

As the manual mentions, there are no exceptions to ZOCs for normal condition and Disrupted infantry and vehicle units.

ZOCs are projected across a river or other hexsides a unit can't move through (like a Cliff), and also into terrain a unit can't legally enter (say, a motorized infantry or tank unit adjacent to a Marsh hex).
