Pacheco Creek is a 3.4-mile-long (5.5 km)[1] waterway in central Contra Costa County, California, United States.[2] It empties into Suisun Bay. It is formed by the intersection of Walnut Creek, Grayson Creek and Pine Creek.
The creek has a run of chinook salmon and steelhead trout after periods of rain in the winter and fall.[3]
Salvio Pacheco, a Californio ranchero and military officer, was granted the Rancho Monte del Diablo in 1834, and settled there in 1844. The creek is named for him.[4]
