Document Title
Emergency Drought Barriers Project
Document Type
MND - Mitigated Negative Declaration
Document Description
Rock (rip-rap) barrier weir structures would be installed at three sites (Sutter Slough, Steamboat Slough, and West False River) between 2015 and 2025. During this 10-year period, the barriers could be installed up to three times, including potentially in consecutive years. The purpose of the barriers is to reduce the intrusion of saltwater into the Delta during drought conditions when stored water in upstream reservoirs available for release is insufficient to meet Delta outflow required to repel San Francisco Bay salinity, which could (1) render Delta water undrinkable and affect roughly 25 million Californians, (2) render Delta water unusable by agriculture, and (3) decrease freshwater habitat in the Delta for sensitive aquatic species.
