[3] A channel was cut through in the 19th century, and Codornices flows directly to San Francisco Bay by way of a narrow remnant slough adjacent to Golden Gate Fields racetrack.

Luis Maria Peralta, military governor at San Jose, divided the land grant among his sons, giving the area that now is Berkeley and Albany to Domingo, who built his home on the banks of Codornices Creek.

The Byrne family was accompanied by two freed slaves, believed to have been Berkeley's earliest African American residents.

The reservoir became part of the East Bay Municipal Utility District system and was enlarged and covered, but has been drained because of fears it might rupture in an earthquake.

In that streetcar era, both parks had busy club houses (now gone; Live Oak's was replaced by the current community center) and large picnic areas with stone fireplaces (still existing).

The overcrossing was removed in 1959-60 after the Key System ceased running its F-train here in April 1958, and more fill was added to bring the uphill portion of Eunice up to the level of Henry Street.

Downstream, Berkeley's first zoning designated the marshy area near the creek and railroad tracks for "noxious industries."

This marsh in turn empties into the Albany tide flats and San Francisco Bay via four pipes under Buchanan Street.

Upstream, water quality also improved by better sewer systems and, as the environmental movement got started, public education about keeping pollutants out of storm drains.

In the late 1990s, the volunteer group Friends of Five Creeks, planting natives at the Bay Area Rapid Transit (BART) crossing, discovered the return of the steelhead/rainbow trout.

This encouraged further restoration, notably below Albina Street adjacent to St. Mary's College High School, carried out by the Urban Creeks Council in 2007.

Stricter regulations and the need for flood control led to a collaboration with the City of Albany and, to a lesser extent, Berkeley, aimed at giving the creek a more meandering channel, with native plantings, along the south edge of University Village.

There are hopes to extend it to San Pablo Avenue, and to restore a shorter portion just upstream at Kains Street, creating a mini-park next to subsidized housing.
