Milliken Creek is an 11.9adj=midNaNadj=mid[1] stream in Napa County, California, that is a tributary to the Napa River.[2] There are approximately 7300acres in this watershed, of which 90acres are developed as vineyards.[3] Milliken Creek rises on the western slopes of the east side of the Napa Valley and flows through the Silverado Country Club property. Much of this watershed property had once been part of the Mexican land grant Rancho Yajome, which had been granted to General Mariano G. Vallejo. Most of this watershed was wilderness area to at least 1869, and thereafter the lower watershed was begun to be developed as pasture and grazing agricultural uses. In a 1989 stream survey by Earth Metrics, the steelhead fishery was found to be robust up to and including the Silverado Country Club.[4]
