LIHI Certificate #12 - Tallassee Shoals Project, Georgia
The Tallassee Shoals Hydroelectric Project is located on the Middle Oconee River .5 miles downstream of GA Hwy 330 in Clarke and Jackson Counties, Georgia. The original dam was constructed in 1895 and the current project was constructed in 1985. Operations began in 1986.
There are two generating units, a 2.2 MW variable pitch Kaplan fed by a 400 yd headrace and a 100 KW submersible fixed pitch Kaplan built within the dam. Both are operational but the 100 KW unit is rarely used due to its relative size and the manual labor required to clean its trash rake. Operations are run of the river with a Georgia Environmental Protection Department required minimum flow between dam and tailrace of 57 cfs. The minimum flow is maintained via computer control with continuous electronic record keeping.
Total available head is 52 feet with usable flows of between 200 and 800 cfs. The dam is of concrete gravity construction is rated as low hazard.

August 13, 2019: The decision to recertify the Tallassee Shoals Hydroelectric Project is final. No appeals were received during the appeal period which closed on August 8, 2019. The new certification term for the Project is from April 23, 2019 through April 22, 2024.
July 9, 2019: The Low Impact Hydropower Institute has preliminarily approved recertification for the Tallassee Shoals Hydroelectric Project. The Certification includes two conditions:Condition 1: The Facility Owner shall provide LIHI with a copy of the agency and FERC-approved study plan for the upcoming in-stream flow evaluation and water quality studies, the final study results, and agency comments on these documents, as part of the annual compliance submittals to LIHI. Based on the PAD re-licensing schedule, it is expected that the study results will be available in 2020. LIHI reserves the right to modify conditions and/or reassess Certification in light of study results, or if a new license changes Project operations related to the LIHI criteria.
Condition 2: The Facility Owner shall notify LIHI within 90 days if state and federal fisheries resource management agencies require the Owner to undertake actions at the Project for upstream or downstream fish passage. Such notification shall include a copy of the agency(ies) requests, the Facility Owner’s response, and the plan and schedule for implementation.
This decision is preliminary pending the 30-day appeal window. Only those who commented on the initial application during the 60-day comment period are eligible to file an appeal. Such appeal needs to include an explanation as to how the Project does not meet the LIHI criteria. Appeal requests can be submitted by email to email@example.com with “Tallassee Shoals Hydroelectric Project” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, 329 Massachusetts Ave, Suite 6, Lexington, MA 02420. All requests will be posted to the website. The applicant will have an opportunity to respond and any response will also be posted. Requests must be received by 5 pm Eastern time on August 8, 2019.

April 29, 2019: The Low Impact Hydropower Institute has received a complete application for Low Impact Recertification of the Tallassee Shoals Hydroelectric Project. LIHI is seeking public comment on this application. Specifically, we are interested in knowing whether you think the Project meets the LIHI Low Impact Certification Criteria, as revised in the 2nd Edition Handbook. Please review the program and criteria in LIHI’s revised Handbook and then review the Project’s application materials below.
Comments that are directly tied to specific LIHI criteria (flows, water quality, fish passage, etc.) will be most helpful, but all comments will be considered. Comments may be submitted to the Institute by e-mail at firstname.lastname@example.org with “Tallassee Shoals Project Comments” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, 329 Massachusetts Avenue, Suite 6, Lexington, MA 02420. Comments must be received on or before 5 pm Eastern time on June 28, 2019 to be considered. All comments will be posted to the web site and the applicant will have an opportunity to respond. Any response will also be posted.
September 12, 2014: The Tallassee Shoals Hydroelectric Project has been certified for a third five year term of low impact certification, effective April 23, 2014 and expiring April 23, 2019. This certification includes the following project-specific condition:
Condition satisfied in 2017 (due to no restoration activity in the project vicinity). There are active and evolving efforts to restore migratory fish populations in the Oconee River basin that may eventually interact with the facility at some point in the future. Therefore, the owner shall monitor the progress of these efforts on a regular and continuing basis, and participate in them when appropriate. Fish species of concern include the robust redhorse, but also all anadromous, catadromous, and diadromous species in the basin as well as state-listed, riverine species such as the Althamaha shiner. Both state and federal fisheries resource management agencies are involved in the recovery efforts, so strong relations with all must be maintained between the owner and the agencies. The owner shall submit a summary report to LIHI on an annual basis, describing the current status of these efforts, the relation between those efforts and the vicinity of the Tallassee Shoals facility, and how the owner is participating in them. This report shall accompany the annual compliance statement to LIHI.
May 30, 2014: LIHI received a comment letter from the U.S. Fish and Wildlife Service regarding the recertification of the Tallassee Shoals Hydroelectric Project. The letter is available to read in full in the “Files” section below.
April 3, 2014: The Low Impact Hydropower Institute has received an application for a third term of certification of the Tallassee Shoals Project. The current certificate is scheduled to expire on April 23, 2014, but LIHI is extending the term to June 30, 2014, to allow for a period of public comment on the application.
August 27, 2009: The Tallassee Shoals Hydroelectric Project has been certified as low impact for a second five year term, effective April 23, 2009 and expiring April 23, 2014.
