What’s New in Sunol Valley?

If you frequent Sunol Regional Wilderness, you may have noticed increased activity in the park. Our crews are kicking off the Fish Passage Facilities within the Alameda Creek Watershed Project. The Alameda Creek Diversion Dam is located on SFPUC lands adjacent to the Sunol Regional Wilderness Park in Sunol and helps collect water in Calaveras Reservoir through a long tunnel. The project will develop fish passage facilities, including a fish ladder and modified screens for steelhead migration into and out of the Alameda Creek Watershed. Alameda Creek has historically supported an impressive diversity of migratory cold water fish, including steelhead trout. This work will help support the restoration of steelhead trout to the Alameda Creek watershed.  Project completion is expected in late 2018.

What to expect during construction:
  • Sunol Regional Wilderness remains open during construction
  • Park users should anticipate seeing increased construction traffic from the Geary Road entrance and along Camp Ohlone Road, which is the main construction access road
  • Temporary Trail Closures will be needed for large vehicle access and for road improvements. Please use alternative trails to Little Yosemite, such as Canyon View Trail, during these times.
  • Please pay attention to construction flaggers and park signage
  • Construction activity is expected Monday thru Friday from dusk to dawn

Calaveras Dam Team participates in the US Society on Dams Conference

Some of our Sunol Valley Project team members are visiting Colorado this week. And they are not visiting to see the snow, but taking part in the United States Society on Dams (USSD) 2016 Annual Conference representing the Calaveras Dam Replacement Project.

As you know, the Calaveras Dam Replacement Project is the largest project of the $4.8 billion Water System Improvement Program (WSIP) to repair, replace, and seismically upgrade key components of the Hetch Hetchy Regional Water System. 

Our WSIP Director Dan Wade and Calaveras Dam Project Manager Susan Hou were joined by the members of our SFPUC Engineering Management Bureau at the conference to present on the construction and challenges with the Calaveras Dam Replacement Project.

The completion of the project is important to the water supply for the Bay Area. 
Calaveras Reservoir, when full, represents nearly half of all the water storage in the Bay Area for the Hetch Hetchy Regional Water System that serves 2.6 million customers. Calaveras Reservoir is a crucial source of water supply during times of drought and when Hetch Hetchy Reservoir supplies are unavailable for any reason. 

Our project construction continues and we have moved over 7 million cubic yards of earth and rock materials to make room for the new dam. We plan to start constructing the replacement dam later this year. The project is over 70% complete.
