In 2017 Western Canal Water District celebrated the 20th Anniversary of the Butte Creek spring-run Chinook Salmon Fish Passage Improvement Project and continues to spread the word on "FunctionFlow. 

A summary of our 2017 community outreach events can be viewed here and highlights of the 20th Anniversary Celebration co-sponsored by the Gorrill Ranch and Northern California Water Association can be viewed here.

Butte Creek is one of only four Sacramento River Tributaries with remaining populations of spring-run Chinook salmon.  Resource agencies and environmental groups value Butte Creek as a keystone in preserving and recovering the spring-run.  According to Newsweek, the project is a symbol and represents a scene that will be repeated scores of times throughout the West in the future.

Construction began in May 1997 and completed November 1997.  Unprecedented partnerships developed during this project were essential to its success.; key stakeholders and participants included:

  • Western Canal Water District
  • California Urban Water Agencies
  • U.S. Department of Interior (USFWS, USBR)
  • California Department of Fish and Game
  • Ray Toney & Associates
  • T&S Construction
  • CH2M Hill

The overall cost for implementing the project was $9.5 million, including all stages of design, permitting, environmental documentation, construction, construction management, and environmental mitigation.  Project funding was provided through an innovative cost sharing partnership among Western Canal Water District, the Department of Interior, the Bay-Delta Accord’s CALFED Category III Program and Tracey Pumps Mitigation Fund.  Additionally, the California Urban Water Agencies provided funding for the Bay-Delta Category III Program.
