"MISSION DAM AND FLUME
AFTER MANY ATTEMPTS DATING BACK TO 1774 TO PROVIDE
A RELIABLE SOURCE OF WATER FOR CROPS AND LIVE-
STOCK FOR MISSION SAN DIEGO DE ALCALA, A DAM
AND FLUME SYSTEM WAS FINISHED BETWEEN 1813 AND
1816 BY INDIAN LABORERS AND FRANCISCAN MISSION-
ARIES TO DIVERT WATERS OF THE SAN DIEGO RIVER FOR
A DISTANCE OF 6 MILES. THE AQUEDUCT SYSTEM CON-
TINUED IN EXISTENCE UNTIL 1831 WHEN CONSTANT FLODDING
CAUSED THE DAM AND FLUME TO FALL INTO DISREPAIR.
