Notice of Supplemental Initial Study/ Mitigated Negative Declaration (IS/MND) for work at Bethany Reservoir (8/14/2018)

DWR has submitted supplemental Initial Study / Mitigated Negative Declaration (IS/MND) for work at Bethany Reservoir in Alameda County.


DWR is proposing to perform additional maintenance activities at Bethany Reservoir’s earthen dams. The proposed project changes include actions to ensure the continued safe operation of the Bethany Reservoir, part of the State Water Project (SWP). These actions include: drainage ditch improvements to control vegetation, improve flow of water away from the dam faces, and for seepage monitoring; and repair damage caused by rodent burrow holes on the Bethany Dams, and prevent future burrow damage. DWR’s Division of Engineering and Division of Operations and Maintenance Dam Safety Branch has recommended these improvements in order to facilitate monitoring and prevent potential damage or failure of the dams.

Notice of Intent to Adopt a Mitigated Negative Declaration for Winter Island Tidal Habitat Restoration Project (8/10/2018) - The Department of Water Resources is the Lead State Agency under the California Environmental Quality Act and has prepared in cooperation with the California Department of Fish and Wildlife a Draft Initial Study and Mitigated Negative Declaration for the Winter Island Tidal Habitat Restoration Project.

  • The Project is located in Suisun Bay between Broad Slough and Middle Slough, just north of the City of Pittsburg, in Contra Costa County. Winter Island sits at the confluence of the Sacramento and San Joaquin Rivers, in the corridor between Browns Island and Sherman Island Waterfowl Management Area. The Winter Island Tidal Habitat Restoration Project is proposed by DWR to restore connectivity to the interior of Winter Island to create aquatic and riparian habitat to benefit native species. Winter Island was formerly managed for duck hunting and currently receives muted tidal flows. The Project will enhance up to 544-acres of tidal wetland, associated high marsh and riparian habitats benefiting listed fish species including Delta Smelt (Hypomesus transpacificus), Chinook Salmon (Oncorhynchus tshawytscha), and Longfin Smelt (Spirinchus thaleichthys).The Project is intended to partially fulfill the 8,000-acre tidal habitat restoration obligations of DWR, contained within the 2008 U.S. Fish and Wildlife Service Delta Smelt Biological Opinion and referenced in the 2009 National Marine Fisheries Service Salmonid Biological Opinion, for long-term coordinated operations of the State Water Project and the federal Central Valley Project.
