California Code, Government Code - GOV § 66672

The Legislature further finds and declares that the area of White Slough was not within the jurisdiction of the San Francisco Bay Conservation and Development Commission from the time the commission was established in 1965 until the winter of 1976-77, when storms and other natural forces caused levees along the Napa River to breach, allowing greater and more frequent inundation by the tides into much of the area of White Slough. Because neither the owners of the property in the area of White Slough, nor any public agency repaired the levees in a timely manner, subsequently in 1977, most of the area of White Slough became subject to the jurisdiction of the commission and thereby subject to this title.
