San Diego Creek Tributary
San Diego Creek is the main tributary to Newport Bay. Its headwaters lie about a mile east of the I-5 - I-405 intersection, at an elevation of about 500 feet. The creek flows westerly from its headwaters and empties into Newport Bay one mile west of the campus of the University of California at Irvine. Portions of San Diego Creek were channelized in 1968 for flood protection purposes.
