The seven-year project features the highest raise of a concrete dam using roller-compacted concrete in the world, according to design firm MWH Global.

When completed in August, the reservoir will be able to store an additional 152,000 acre ft of water. That will better enable the San Diego County Water Authority to carry over surplus water from rainy periods to sustain the region in times of drought.
