Summary of the Project: 

The Bureau of Land Management’s Mother Lode Field Office (BLM) proposes to restore 154 acres of valley oak (Quercus lobata) riparian forest by restoring the historic floodplain and slough channel connectivity with the Cosumnes River.  The project would breach a low-lying inactive agricultural levee in two locations along the Cosumnes River Preserve’s (Preserve) Cougar Unit, located south of Twin Cities Road in the lower, tidally influenced section of the Cosumnes River. 

Currently, the Cougar Unit is managed as a seasonal wetland unit for winter migratory waterfowl and waterbirds.  However, due to the proximity of the Unit to the river, the unpredictable natural flooding cycle of the river, the ineffectiveness of the low-lying agricultural levee, and the cost-to-benefit ratio of continuing to try to manage it as a seasonal wetland in an unmanageable area, the BLM and its implementing partners at the Preserve have determined that the most appropriate use of the area is to restore it to its natural, historic function as forested floodplain habitat.

The benefits of the restoration project will be to:

  • Protect, maintain, and restore riparian and floodplain communities in the lower Cosumnes River watershed
  • Restore the natural hydrologic processes that sustain the riparian and floodplain habitat and the native species that depend on the habitat
  • Restore a small portion of the slough channel habitat that once existed historically in the lower Cosumnes River area
  • Assist in the restoration of a viable population of fall-run Chinook salmon in the Cosumnes River with an average annual spawning run of 2,000 adults (10-year average)


In accordance with the National Environmental Policy Act of 1969, as amended, and the Federal Land Policy and Management Act of 1976, as amended, the Bureau of Land Management (BLM) has prepared a Draft Environmental Assessment (Draft EA) for its proposed Cougar Floodplain Restoration Project.

The Draft EA will be available for public comment for 30 days.  All comments received on the Draft EA by March 1, 2014, will be considered and addressed in a Final EA, as appropriate.  

The BLM will not issue a final decision on the proposed action until approximately May 2014, pending the completion of all applicable permitting requirements.  If approved, the BLM anticipates that the project would begin on or around June 1, 2014.  

Copies of the Cougar Floodplain Restoration Project Draft EA are also available for public inspection at the Cosumnes River Preserve Visitor Center.
