Description
Scope/Content: Abstract: This document presents the findings of geotechnical studies on an existing Upper York Creek earthen dam located along York Creek approximately two miles northwest of the City of Saint Helena in Napa County, California. The primary objective of the studies is to evaluate the subsurface conditions of the dam's foundation and the nature of the embankment fill as they relate to the various options for removing the dam and the sediments that accumulated upstream. The dam is considered an impediment to the upstream passage of anadromous fish species, in turn degrading fish spawning and rearing habitat. The California Department of Water Resources (DWR) reported that in the past the dam has experienced overtopping failures releasing silt downstream.
