Duke Energy continues moving water through its river basins, urges caution as Helene increases flood risks in the Carolinas, particularly along the Catawba-Wateree River Basin

Rhea-AI Summary

Duke Energy is urging caution as Tropical Storm Helene increases flood risks in the Carolinas, particularly along the Catawba-Wateree River Basin. The company expects lake levels to rise sharply due to heavy rains from Helene, adding to the significant rainfall the region has already received this week.

Duke Energy manages 11 lakes and 12 hydroelectric stations in the basin and has been aggressively moving water through the system in preparation for Helene's arrival. Despite these efforts, historic flooding is possible in several areas. The company is collaborating with local emergency management officials and advises residents in flood-prone areas to stay informed and alert.

Real-time lake level information is available on Duke Energy's website, mobile app, and through a dedicated phone line. Residents are encouraged to follow instructions from state and county emergency management and monitor emergency notifications on their mobile phones.

Negative

• Increased risk of flooding, particularly along the Catawba-Wateree River Basin
• Potential for historic flooding in several areas despite preparatory measures

• Lake levels expected to rise sharply as heavy rains from Helene add to the many inches of rain the region already received this week
• Those living along lakes, rivers and in flood-prone areas should exercise caution, stay informed and remain alert

CHARLOTTE, N.C., Sept. 26, 2024 /PRNewswire/ -- Helene's projected rainfall in the Carolinas has increased significantly, raising concerns about potential flooding, particularly along the Catawba-Wateree River Basin.

"The western Carolinas region has received heavy rains this week unrelated to Helene," said Jason Hollifield, Duke Energy's storm director in the Carolinas. "Meteorologists believe Helene will bring more precipitation than previously forecast, leading to an increased risk of flooding."

Duke Energy oversees the chain of 11 lakes and 12 hydroelectric stations that make up the Catawba-Wateree River Basin. It manages the lakes' water levels by moving water through its generating units and, where possible, operating spillway gates. Water management in one lake often impacts others.

The company began aggressively moving water through the Catawba-Wateree River Basin earlier this week in anticipation of Helene's arrival. Even with these preparations, lake levels are expected to rise sharply and may not be able to store excess water from the expected rain and increased inflows from upstream. This could lead to historic flooding in several areas.

Although rainfall amounts can be unpredictable, Duke Energy encourages communities along the Catawba-Wateree River Basin to prepare for flooding conditions and to closely monitor local lake levels.

"We strongly urge those living along lakes, rivers, and in flood-prone areas to exercise caution, stay informed and remain alert to changing weather and streamflow conditions," said Hollifield. "Residents should follow the instructions of state and county emergency management and keep an eye on emergency notifications sent to their mobile phones."

Duke Energy is actively collaborating with local emergency management officials to ensure they are informed of any changes in water levels. Local authorities will notify residents should evacuations or electrical disconnects be necessary.
