NO. 52 MISSION DAM AND FLUME - After many attempts dated back to 1774 to provide a reliable source of water for crops and livestock for Mission San Diego de Alcala, a dam and flume system was finished between 1813 and 1816 by Indian laborers and Franciscan Missionaries to divert waters of the San Diego River for a distance of 6 miles. The aqueduct system continued in existence until 1831 when constant flooding caused the dam and flume to fall into disrepair. They were not repaired due to secularization of the missions.
