Appalachian Power has announced that it will hold its annual capacity testing of generators at Leesville Dam on Thursday, July 13, beginning at approximately 3 p.m.
It will have an impact on areas downstream from Leesville Dam. The test is not expected to create hazards downstream, but Appalachian urges recreational and commercial users of the Staunton River to be aware of the higher and faster temporary water flows that could increase the water level by up to 8 feet.
As testing of the generators ramps up, there will be an increased water flow downstream that peaks at the dam between 10 and 11 p.m.
Appalachian expects the maximum river levels at Altavista to gradually increase by 8 feet, peaking at around 1 to 2 a.m. on Friday, July 14, and then gradually decreasing to normal levels during the remainder of Friday.
As an example, if normal river levels remain where they were on Tuesday, July 11 (3.6 feet or so), Altavista could expect to see the river rise to a level of 11.6 feet early Friday morning before dropping back off as the water dissipates.
Warning sirens at the dam will be sounded before each period of power generation. The public fishing area below the dam will be affected as water height rises.
Weather or other circumstances could change the time of the test.
