California EcoRestore (EcoRestore) is a multi-agency initiative launched in 2015 to advance at least 30,000 acres of critical habitat restoration and enhancement in California’s Central Valley including the Sacramento-San Joaquin Delta (Delta), Suisun Marsh, and Yolo Bypass region. EcoRestore and its partners pursue complex multi-benefit habitat restoration projects to deliver results. The EcoRestore initiative was built on the assertion that cutting-edge science, strong partnerships, and a healthy impatience could drive more restoration than had ever been pursued in the Delta.  

The Department of Water Resources (DWR) is a lead partner on a majority of projects focused on implementing a comprehensive suite of habitat restoration actions to support the long-term health of the Delta and its native fish and wildlife species.  After five years of work, DWR and its partners are within reach of doubling the Delta’s restored and protected habitat lands. Our EcoRestore 5-Year Highlights fact sheet shows just how far we’ve come and gives a glimpse of what’s ahead.

Currently, EcoRestore includes 32 projects representing an investment of nearly $500 million to date. EcoRestore projects are funded by multiple sources, including the State Water Contractors through operation of the State Water Project, and funding allocated to restoration, multi-benefit, and flood needs through bonds, propositions, general fund, and other special funds. The overall estimated cost to complete the current list of 32 EcoRestore projects is $750-$950 million with approximately half from the State Water Project and half from other funding sources.

Specifically, the program aims to achieve:

As part of an ongoing effort to protect and restore critical habitat in the Sacramento-San Joaquin Delta, DWR has restored more than half of the 1,187 acres of former grazing and dairy lands into rich habitat for fish and wildlife as part of the Dutch Slough Tidal Marsh Restoration Project.
