Discover more about Old Mission Dam

The Old Mission Dam, also known as Padre Dam, is a significant historical landmark located within Mission Trails Regional Park in San Diego, California. This enduring structure offers a glimpse into the early days of California's colonial past, showcasing the ingenuity and collaborative efforts of Spanish missionaries and the indigenous Kumeyaay people. Constructed between 1803 and 1817, the dam was designed to provide a reliable water source for the Mission San Diego de Alcalá, the first Spanish mission in California, founded by Father Junipero Serra. Prior to the dam's construction, the mission faced significant challenges due to frequent droughts that plagued the region. Recognizing the need for a sustainable water supply, the Franciscan padres devised a plan to harness the flow of the San Diego River. The Kumeyaay people, who had inhabited the area for centuries, contributed their expertise and labor to bring this vision to life. The dam was built using locally sourced materials, including stone, brick, cobblestones, and cement, showcasing the resourcefulness of the builders. Originally, the Old Mission Dam measured approximately 220 feet in length, 13 feet in width at its base, and 12 feet in height. It impounded the waters of the San Diego River, creating a reservoir that could be drawn upon during dry periods. A sophisticated aqueduct system, stretching approximately five miles, transported the water to the mission's agricultural fields and settlements. This irrigation project was the first of its kind on the Pacific Coast, enabling the mission to thrive and support a growing community. However, the dam's period of utility was relatively short-lived. Following the secularization of the missions in 1833 by the Mexican government, the dam fell into disrepair. By 1867, it was largely in ruins, and the aqueduct system was lost to time and neglect. Despite its decline, the Old Mission Dam remained a significant landmark, a reminder of the region's early history. In the years that followed, efforts were made to preserve and restore the dam. Today, visitors can explore the remaining structure, which has been designated a National Historic Landmark and a California State Historic Landmark.
