Fish do it all the time and there are a lot big ones in DVL.. Just another reason to keep BIG Stripers..LOL
UPDATE: Diamond Valley prohibits the release or introduction of boneless browns in to the lake. Much like stripers boneless browns are found both fresh and saltwater. They are invasive species that flows in from up stream. No matter how hard they try to keep them there are always a few boneless browns that manage to make it to a lake.
