Lagunita Diversion Dam


Project Description

The Lagunita diversion dam was constructed in the late 1800s as one of Stanford’s original facilities to supply water to the campus. It consists of a dam, intake structure and a channel to carry water to Lake Lagunita on campus.
In the 1950s, the California Department of Fish & Game (CDFG) approached Stanford regarding fish passage at the dam and a fish ladder was installed by CDFG. The fish ladder has since undergone various modifications by both CDFG and Stanford over the years.

The facility was abandoned as a water diversion facility in 1985 and Stanford no longer relies on it for water supply. For many years, Stanford has wanted to remove the concrete from the Creek and restore the channel to a natural state. Over the last several years, Stanford has discussed the concrete dam with state and federal resource agencies and the agencies also agree that removal of the diversion dam and restoration is the best approach. This restoration will be done with bank and creek bed stabilization features consisting of large rock boulders, logs and crib walls designed to create a combination of pools and riffles patterned after those naturally occurring elsewhere in the Creek.

During construction, access will be from the Stanford/Santa Clara side of the Creek.

We currently expect construction will take approximately six months and will begin this year at the end of May.

While our construction schedule necessarily assumes appropriate creek conditions (no unusually high and/or prolonged flows in the Creek like we saw in 2017) and permits from various agencies, we are doing everything we can to complete this project in 2018 as currently scheduled.
