The Sausal Creek, located in Oakland, California, runs from Montclair through Oakmore Highlands, Dimond, etc. all the way to the Oakland Estuary. It is fed by Palo Seco Creek which comes out of Joaquin Miller Park, and Shepherd Creek, which flows down Shepherd Canyon.
Sausal means "willow grove" in Spanish; the creek used to flow through a willow grove on the lower stretches. Over the years, various parts of the creek were put into underground culverts, but much of the creek is still above ground. In 2016, a previously undergrounded part of the creek in Dimond Park was uncovered.
The section of the creek which ran through the Dimond District was not always a "slender body of water." It appears from an old photo that there was once enough water flowing in the creek for people to swim, even in the warm summertime when the water level of most creeks sinks and/or disappears. In the photo below, this stretch of Sausal Creek south of Dimond Park was dammed to allow swimming.
