§ 23074 Waterway Boundary Definitions

• •When a law talks about something happening 'to,' 'by,' 'along,' 'with,' 'in,' 'up,' or 'down' a creek, river, slough, strait, or bay, it means the middle of the main channel of that water body.
• •This rule helps figure out where exactly something is supposed to happen or be located in the water.
• •It applies to all kinds of waterways, like rivers, creeks, and bays.

If a law says you can't fish 'along' a river without a permit.

This means you can't fish in the middle part of the main channel of that river without a permit.
