~ Duke Energy – Lake Tillery Draw Down ~
Dear Community Leader,
Good morning, I trust you are doing well today. I wanted to make you aware that Duke Energy Progress is providing notification of the potential for visitors and residents of Lake Tillery to experience lower than normal lake levels from Nov. 28 through Dec.19, 2016. This is due to water flow coordination needs resulting from required maintenance activities at Blewett Falls Hydro Station located downstream of Lake Tillery. With unusually low stream flows in the Yadkin-Pee Dee River Basin, these required maintenance activities could also result in lower than normal flow releases from Blewett Falls Hydro Station. Additional flow releases from Lake Tillery may be needed to meet the federal operating license requirements for flow releases from Blewett Falls Lake.
Without additional rainfall in the area, the level of Lake Tillery could be as low as 5 feet below full pond by the end of the outage period. Significant rainfall could increase the water availability in Blewett Falls Lake and reduce the need for additional flow releases from Lake Tillery during the outage. This notification is being provided in the event that dry conditions persist.
The drawdown limit for Lake Tillery for most of the year is 1 1/2 feet below full pond on weekends and 2 1/2 feet below full pond on weekdays. These limits change between Dec. 15 and March 1 when the minimum lake level can be as much as 3 feet below full pond under normal conditions. Drawdowns of up to 8 feet below full pond may occur during system emergencies and may be greater during periods of drought.
Please feel free to share this information with your staff or others in the community that you feel would want to be aware of this information.
Thanks in advance for your understanding as we perform this needed work. Feel free to reach out to me as well with questions.
