Los Vaqueros Project Facts
Purpose
Improve water quality for CCWD's 500,000 customers. This is being accomplished by storing higher-quality Delta water from wet seasons for blending with the Delta supply during dry periods.
Provide a 1-to-3 month supply of emergency water storage.
Other benefits include recreation, flood control, and protection of rare natural and historic resources within the watershed.

Vasco Road
The previously existing Vasco Road has been inundated. It has been replaced by a new road that begins at Camino Diablo, and extends east around the Los Vaqueros watershed.
The new road consists of almost 13 miles of two-lane highway, with climbing lanes where needed. It also has softer curves, and areas where drivers can pull over, if necessary.
