California Stream Access Laws

The courts have described the reach of the California public right of navigation as “the right to navigate and to exercise the incidents of navigation in a lawful manner at any point below high water mark” on waters that satisfy California’s small craft test. Thus, property owners cannot interfere with the public’s right to navigate or use shoreline areas below the ordinary high water mark for incidents of navigation. In fact, unauthorized obstruction of the public’s right to access and use a navigable waterway constitutes a public nuisance.
