This is one of my favorite places in San Diego to take walks and photos. A bit of history:
The Old Mission Dam is a historic water impoundment structure built around 1803 in San Diego. It was built to impound the San Diego River to provide water for irrigation of the fields associated with the Mission San Diego de Alcalá, the first Spanish mission in what is now California. It was the first major colonial-era irrigation project on the Pacific coast of the United States. The surviving remnant of the dam was designated a National Historic Landmark in 1963.
