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
