Sacramento Valley Water Users – Advancing Innovative and Comprehensive Projects to Benefit Salmon
July 02, 2018
Sacramento Valley water users have completed dozens of projects in recent years to benefit fish. From restoration of spawning habitat to fish screens to fish food, water districts and agencies have been focused on implementing innovative and comprehensive projects. The visual element to many of these projects, as well, hearing directly from the partners involved, helps put the size and scope of the projects into perspective. Listed below are some examples of those projects with links to videos detailing the projects.
As part of ongoing efforts to address all stages of the fish life cycle on the Sacramento River, Glenn-Colusa Irrigation District was part of a collaborative group of local, state and federal agencies that completed a project to restore side channel rearing habitat in the Sacramento River, immediately upstream of the Cypress Avenue Bridge on the east side of the river, in Redding.
Market Street Salmon Spawning Habitat Restoration Project
March 01, 2016
In partnership with local, state and federal agencies, Glenn-Colusa Irrigation District (GCID) constructed the Market Street Bridge gravel project in Redding, CA to restore salmon spawning habitat. The project was completed in March 2016.
The project, carried out over several weeks, placed salmonid spawning gravel in the Sacramento River, immediately below the Anderson Cottonwood Irrigation District Diversion Dam and Market Street Bridge in Redding.
Painter’s Riffle Anadromous Fish Habitat Enhancement Project
December 01, 2014
As part of ongoing efforts to protect fisheries, GCID was part of a unique partnership that developed and designed the Painter’s Riffle Anadromous Fish Habitat Enhancement Project to enhance salmon habitat that was obstructed by a major storm. The restoration project was designed to reopen Painter’s Riffle, a historic salmonid spawning side channel on the Upper Sacramento River, downstream of the Highway 44/299 Bridge.
Glenn-Colusa Irrigation District (GClD) has historical water rights on the Sacramento River dating back to 1883, and was one of the first large-scale agricultural water users. The District conveys Sacramento River water through irrigation canals to approximately 141,000 acres of valuable, productive agricultural land. In addition, GClD delivers water to 20,000 acres of critical wildlife habitat comprising the Sacramento, Delevan, and Colusa National Wildlife Refuges.
Sacramento River Channel Gradient Restoration Facility
June 01, 2003
A major flood in January 1970 significantly changed the shape and flow of the Sacramento River downstream of the Glenn-Colusa Irrigation District (GClD) intake channel . Approximately 4 miles north of Hamilton City, a meander was cut off, which reduced the river reach by approximately 2 .5 miles (RM 202.5 to RM 205) . The riverbed gradient within this reach continued to degrade with seasonal flood events. The degraded river gradient decreased water surface elevations by 3 feet at the GClD diversion, leaving much of the fish screen out of the water. The lower water elevations contributed to unacceptable fishery losses at the existing drum screen facility.
The fish screen and gradient restoration facility were designed and constructed to benefit fish, particularly protected species of anadromous (i .e. migratory) fish, such as Chinook salmon and steelhead trout. These facilities enable GClD to divert its full entitlement of water with minimal impact to fish. This benefits people by helping farmers to grow the food that feeds our country and keeping the Sacramento Valley economy vibrant. The facilities also allow GClD to deliver a reliable water supply to three national wildlife refuges to maintain and enhance critical habitat for waterfowl and other wildlife.
