North Delta Drought Salinity Barriers Project	The Department of Water Resources is proposing the North Delta Drought Salinity Barriers Project (Project) to maintain water quality within the Sacramento-San Joaquin Delta. The proposed Project consists of installing two temporary rock barriers, on Miner and Steamboat sloughs, that are designed to control salinity intrusion from the Central and South Delta by keeping more freshwater flow in the Sacramento River. Each barrier consists of a trapezoidal embankment rock structure with a wide base that tapers up to a 12-foot-wide top set perpendicular to the channel alignment. Both barriers have a manually operated fish passage culvert that can be opened periodically to allow fish passage. The proposed Project also includes a boat ramp at the Steamboat Slough barrier site.	12/16/2022
