San Francisco is high and dry as the SFPUC cut water delivery from Hetch Hetchy for at least a month.

The shutdown is part of a planned outage to allow for maintenance on the aging water delivery system and is expected to last until mid- to late-February.

The shutdown will allow work to be undertaken on the $4.6 billion, 12-year Water System Improvement Program, which aims to upgrade and maintain the water delivery and storage system and protect it from earthquakes.

In anticipation of the shutdown, the flow of water from Hetch Hetchy into Bay Area reservoirs was dramatically increased in recent weeks.

    “500K Fish Moved for SF Pipe Fix

    The California Fish and Game Department recently transported 500,000 fish of varying sizes by tanker truck from the Moccasin Fish Hatchery to a hatchery in Fresno because of repairs to the Hetch Hetchy water system that have stopped flows.

    The fish, moved in late December, will eventually come back, but the fishery interruption is sure to reduce trout stocking numbers this spring, according to the Fish and Game Department.”
