ok, I am a regular to the area and have been fishing bubbles for about 9 years in a row now so just to clear some things up, you can fish the tunnel underneath the highway at any given time, it is part of the tidal system because on the other side of the highway there are tidal gates that restrict the amount of water released from the park, and all other regulations apply, it is open year round and there is a 12 inch minimun size limit and you can keep 3 fish per man, hope that helps some
