Despite the recent heavy rains, the crews at the Calaveras Dam Replacement Project have been pouring concrete for an important feature of the future Dam – the stream maintenance building, pictured below. The new building stands 25 feet tall and is located downstream at the toe of the future replacement dam.
We at the SFPUC will be releasing water from the future Calaveras Dam to support fish in the Southern Alameda Creek Watershed. What’s that have to do with this building? A lot, actually. The stream maintenance structure provides a place for water discharged out of the future Dam to be collected and then discharged in a controlled manner to the nearby Creeks to support fish habitat. Water will flow from the reservoir to the structure via two 30 inch diameter pipes. Water will exit the structure over grouted rip rap to prevent erosion.
The Calaveras Dam Replacement project is more than 80% complete and expected to be completed in mid-2019.
