Georgia Power's Sinclair Dam
|
|
This dam, part of the Central Georgia Hydro Group, is located near
Milledgeville, GA, on the Oconee River. We saw this dam featured on the
local news recently after one of the few heavy rains we have had, with
the floodgates open. It was too late in the day for us to make it down
there to grab some pictures... maybe next time.

The dam, completed in 1952, stands 104 feet high and
2,988 feet long. It consists of concrete non-overflow and spillway
sections, flanked by reenforced earthen embankments. The spillway has 24
30 foot wide floodgates. Two turbine/generator assemblies can produce
22.5 Megawatts each, at an average head of 90 feet and flow rate of
4,000 cfs, for a total of 45 Megawatts at 8,000 cfs.
