Facility Type Run-of-river
FERC No. 6951

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 Ga EPD 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.

Certification History

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:

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.
