Today Kongo visits the Old Mission Dam in San Diego. Embarrassingly, Kongo has lived within a few miles of this interesting site for many, many years and this was his first visit. The dam was built on the San Diego river by mission padres and indians in 1813 to provide a regular water supply to Mission San Diego de Alcalá located five miles away. It was the first major irrigation project on the Pacific Coast.The opening in the dam seen in the first photo once housed an adjustable spillway door that regulated the water in the dam and the supply downstream.
The Old Mission Dam is part of the Mission Trails Regional Park, one of the largest urban parks in the United States. You can hike or drive to the dam. Learn more about the dam and Mission Trails park here.
