Welcome to the Water Authority's Photographic Tour of the Olivenhain Dam and
Reservoir
The Olivenhain
Dam is the first major dam built in San Diego County in 50 years. At 318
feet tall, it is the largest roller-compacted concrete dam of its kind in North
America. The reservoir holds 24,000 acre-feet of water – enough water
for a year for about 50,000 families. On August 6, 2003, the first
water flowed from the San Diego County Water Authority’s Second Aqueduct
into the Olivenhain Reservoir.
Project construction was a very exciting
process. The Olivenhain Dam was built in
four main phases. This photographic tour will take you
through the phases and provide an explanation of the work involved.
