Addressing Hydro Impacts on Yuba River Salmon: Public process brings focus on potential solutions

Public is asked to attend July 10^th Public Meeting 

On July 10^th, the Federal Energy Regulatory Commission will hold a public hearing regarding the relicensing of the Narrows 1 Project located on the lower Yuba River in Nevada County.  

Below is background on relicensing of the Narrows 1 Project and more information about the upcoming public hearing and opportunity to comment.  

What is “Relicensing”? 

The Federal Energy Commission (FERC) is charged with the licensing of non-federal hydroelectric dams. These legally binding licenses require dam operators to meet certain conditions on the river and may include additional conditions such as recreational access, minimum river flows, and monitoring of fish.     

Many of the dams in the Yuba watershed were built before modern environmental laws, and the license conditions at that time did not consider native fisheries, recreational uses, or the negative impacts associated with dam operations. As these licenses were issued for 40-50 year lifespans, many of the hydro projects in the Yuba watershed are still operating under licenses and conditions that were developed when hydroelectric operations began.   

Given that these licenses can last up to 50 years, relicensing is a once-in-a-lifetime opportunity to look at how the dam is operated and negotiate conditions that can mitigate hydroelectric operations and help restore flows and habitat for the fishery.  Relicensing can help ensure that our water resources are managed in a way that balances hydro power generation with the long-term health and resilience of our rivers and ecosystems. 

Englebright Dam and Narrows 1 

SYRCL is now engaged in a relicensing proceeding on the Narrows 1 Project that includes a powerhouse and associated infrastructure that utilizes water from the Englebright Reservoir. Initially owned by PG&E, the original Narrows license was issued in 1966; however, the license was transferred to Yuba Water Agency in 2023 and is now set to expire on January 31, 2026.    

Englebright Dam was constructed on the Yuba River as a debris dam – it was meant to catch sediment and mining debris. Now its main functions are for lake recreation and hydropower generation. Englebright does not provide any flood protection. 

At 260 feet, Englebright Dam is a towering structure that blocks access to many miles of upstream habitat that previously hosted the spawning of hundreds of thousands of salmon. The dam’s hydroelectric operations also disrupt the natural flow of water, which has significant impacts downstream. Increased flows during the summer months to meet irrigation and power demands and lower flows especially during early fall storms conflict with the natural hydrologic pattern native fish evolved with. Additional impacts from Englebright Dam, and most dams, include preventing the downstream movement of sediment, nutrients, and large wood which is an important component of rearing habitat. 

Currently, the only way for controlled water releases to exit Englebright reservoir is through the two outlets used for hydropower electricity generation, Narrows 1, and Narrows 2, which is not being considered through this process. These two outlets have a combined capacity of about 4,300cfs. When the Yuba River is high, flowing above 4,300 cfs, the water will also spill over the dam’s rim, which is part of the dam’s design. Both power outlets are under the ownership, operation, and maintenance of the Yuba Water Agency (YWA).

The Yuba River Development Project: studies reveal negative impacts to downstream habitat 

Beginning in 2006, SYRCL worked with our allies at the Foothills Water Network on a collaborative proceeding to relicense YWA’s Yuba River Development Project (YRDP). As part of the relicensing process, SYRCL advocated for studies to better understand the impacts of Narrows 2  and upstream hydroelectric projects on the North Yuba, Oregon Creek, and Middle Yuba, including New Bullards Bar. These studies were used to help guide license conditions and measures to mitigate the impact of the full hydroelectric projects. One critical study that came out of this process was an understanding of the impacts of the Narrows 2 outlet on the downstream habitat in the Lower Yuba. The environmental impacts and limitations studied as part of Narrows 2 relicensing are just as relevant to Narrows 1 licensing.

At issue is the fact that the two existing outlets (Narrows 1 and 2) can’t release enough water to inundate the floodplains of the lower Yuba River. The current combined capacity of the outlets is just over 4,000 cfs, but the release needs to be about 5,000 cfs to inundate the unrestored floodplains. 

Without flooding, the vegetation and habitat along the riverbanks struggles to grow. That habitat is necessary for the growth of young Chinook salmon and steelhead. For these fish to fully benefit, the floodplains need to be covered with water for ideally 21 days. According to the modeling and studies that were completed during YRDP relicensing, this happens about once every three years. The limitations of the outlets means that the current regulatory flows are not enough to inundate existing habitat or benefit salmon. 

Those studies and conclusions were part of the YRDP relicensing process and focused on the environmental impacts of only those YRDP projects, including Narrows 2. Narrows 1 is a wholly different project and relicensing proceeding, despite being part of the same dam infrastructure and operated jointly by the same agency. FERC sees these as different projects. The Narrows 1 relicensing is therefore an opportunity to once again make the case for flows for salmon in the Lower Yuba.  

In our past comments, SYRCL has asked that YWA study adding more infrastructure (such as another pipe or outlet) so that sufficient water can be released in a controlled manner and inundate the lower Yuba floodplain. SYRCL has also raised other issues about water temperature, monitoring juvenile outmigration, safe and legal river access to the Narrows Canyon below Englebright, and how quickly the reservoir is filling with sediment, its designed purpose. 

Englebright Dam is part of the project and under FERC jurisdiction 

In our past comments, SYRCL urged FERC to recognize and include Englebright Dam as a crucial and integral part of the Narrows 1 project.   

The operation of the Narrows projects rely entirely on the water from Englebright. If the dam were removed or changed, significant adjustments would be needed for the project to continue its operation and power generation. Despite the dam being owned by the U.S. Army Corps of Engineers (USACE), it is operated entirely by Yuba Water Agency, which also holds the sole water rights for the dam. The State Water Resources Control Board (SWRCB) and the USACE recognize that the primary purpose of Englebright Dam and Reservoir is now power generation.   

Public meetings on July 10^th  

In January of 2024, SYRCL and our allies in the Foothills Water Network filed comments with the Federal Energy Commission (FERC) requesting formal studies to help restore salmon in the lower Yuba River. Our comments also focused on the YWA’s Final License Application for the project and are part of the relicensing of the Narrows 1 Project located on the lower Yuba River.  

The next big step is scoping for the environmental review of the impacts of the proposed license.  Scoping is all about identifying what environmental impacts need to be studied, deciding how thorough that analysis needs to be, and gathering valuable input or information from the public. As part of this, FERC is holding two public meetings on July 10^th at 10:00 am and 6:00 pm.

SYRCL is planning on attending the 10:00 am meeting which will focus on the concerns of resource agencies, non-governmental organizations (NGOs), and Indian Tribes.

The evening meeting will focus on receiving input from the public.

 If you would like to attend and learn more about the issue, see FERC’s notice below.    

Comments on the FERC’s Scoping Document 1 (SD1) are due after the public meetings on August 6^th.

Fast facts about Hydropower Projects on the Yuba: 

• Outdated license requirements threaten salmon 
• Many of the hydroelectric dams on the Yuba are still operating under license requirements and conditions that were issued in the 1960s, long before the advent of our modern environmental laws.   Given that licenses are good for 40-50 years, these projects are operating with those same original requirements and conditions, with automatic annual extensions granted by FERC.
