Daguerre Point Dam Hydroelectric Project

Lower Yuba River, California.

Project Profile & Applicant

FERC Project No.14432 is proposed along the southern side of the lower Yuba River, next to the U.S. Army Corps of Engineers’ Daguerre Point Dam, in Yuba County, California. This 3 megawatt Project is the first proposal in California to use “Archimedes-Screw Turbines” (Screw-turbines) to generate power. The Applicant is Archon Energy 1, Inc. (AE).

The proposed Project would consist of the following facilities:  A Water Intake/Diversion Device upstream of Daguerre Point Dam that diverts water from the lower Yuba River into a Power Canal. The Power Canal delivers water into a 115-foot by 65-foot by 35-foot Powerhouse containing an array of eight 375 kilowatt Screw-turbines. The Powerhouse would discharge into a Tailrace Canal that discharges into the lower Yuba River. The Project also proposes to develop a “natural” Fish Passage Facility between the Powerhouse and the southern abutment of the dam.

Federally Threatened - Listed Species/Species of Concern

  1. The distinct population segment (DPS) of California Central Valley (CV) steelhead (Oncorhynchus mykiss) and its critical habitat;
  2. The evolutionarily significant unit (ESU) of spring-run Chinook salmon (O. tshawytscha) and its critical habitat;
  3. The DPS of North American green sturgeon (Acipenser medirostris) and its critical habitat;
  4. The ESU of CV fall-run Chinook salmon (O. tshawytscha) [Species of Concern]; and
  5. Any resident rainbow trout (O. mykiss) (as this form may exhibit an anadromous lifestyle periodically).

FERC Relicensing Status

Preliminary Permit Application (PPA) and Traditional Licensing Process (TLP): AE filed its PPA in July 2012 and a NOI/PAD and TLP request in August 2012. NMFS and other parties provided comments in August and October 2012. FERC approved the TLP use in August 2012 and issued the Preliminary Permit in January 2013. NMFS provided study requests for the TLP in February 2013. AE filed several draft Study Plans in September and November 2013. NMFS commented on all of the draft Study Plans in January 2014. Currently, NMFS and other parties are awaiting the next version of AE’s proposed draft study plans.
