Sacramento River Salmonid Habitat Improvement (35-50)  - These projects fall under the Central Valley Project Improvement Act (B) (13) Program. The goal of this program is to increase and improve salmon habitat and survivability in the Sacramento River. The Bureau of Reclamation is the primary partner and funder for these projects.


Program components include:

  • Injecting spawning gravel into the Sacramento River to improve anadromous fish spawning habitat.
  • Reconnecting side channels to the main river to increase shelter and rearing habitat for juvenile salmonids.
  • Bank revegetation using native plants.

This large-scale restoration program includes:

  • Market Street Gravel Injections: 11,900 tons of spawning gravel was added to the river at the Market Street Bridge in Redding, California.
  • Keswick Dam Gravel Injections: 20,000 tons of spawning gravel was added to the river just below Keswick Dam. Gravel will continue to be added periodically to the river at this location.
  • North Cypress Side Channel Project:  The North Cypress Side Channel Project is designed to reconnect the upstream and downstream ends of old side channels to increase juvenile salmonid rearing habitat. The project is funded by the Central Valley Project Improvement Act and is being developed by the Bureau of Reclamation with Glenn-Colusa Irrigation District providing large equipment operators. The project was completed January 2, 2017.
  • North Tobiasson Deep Water Rearing Structures: 25 six ton structures were placed in a deep channel of the Sacramento River near Bonnyview Bridge. The structures, consisting of tree roots and canopies bolted to boulders, will provide deep water rearing habitat for juvenile salmonids. They were placed in an effort to restore a portion of the historical habitat complexity of the Sacramento River as part of a continuing effort to restore salmonid populations. This video provides additional information on the project. You can view a video of the construction here. This project was completed in early May 2017. A video survey was conducted using a sonar camera on August 16, 2017 by Dave Vogel. The WSRCD is providing monitoring and maintenance on the structures for up to five years.

The proposed side channel project is part of a continuing effort to help meet requirements of the Central Valley Project Improvement Act, and  would reconnect existing ponds and low-lying areas to the Sacramento River to provide juvenile rearing habitat for Chinook salmon and Steelhead trout at all flow levels.
