Water Department Meeting Recap: Addressing Concerns After Hurricane Helene

On October 25, 2024, the County held a meeting focused on providing updates from the Water Department regarding the performance of our county dams and spillways during Hurricane Helene, which impacted us in late September. This meeting was specifically called to address public concerns and questions surrounding the safety of North Fork Dam, particularly rumors about a potential failure. The meeting was attended by County officials and Water Department staff, including Clay, the Water Resources Director, who led the presentation.

The primary focus of the meeting was a detailed explanation of how North Fork Dam and its spillways functioned during Hurricane Helene. Clay explained that the reservoir was initially below full capacity, but rapidly filled to its maximum level and beyond during the storm. Crucially, when water levels reached a critical point (7.5 feet above full pool), the auxiliary spillway activated, releasing water through a mechanical system of concrete "buckets" – a design feature that Clay emphasized likely prevented the dam from failing. An emergency spillway was also activated, creating a significant flow of water that may have impacted nearby transmission lines. The performance of the Brewell treatment plant and reservoir in B-Tree was also highlighted, confirming it functioned as designed and prevented a potential dam failure there.

While the presentation provided reassurance about the current safety of both North Fork and Brewell dams, engineers will be conducting repairs on both facilities. Importantly, Clay emphasized that the Water Resources Department has no ability to manually release water from reservoirs; releases only occur through spillways, either as designed or during emergency situations like Hurricane Helene. He also underscored the potential devastation a failure of North Fork Dam would have caused, stating that it could have resulted in "complete annihilation" between Black Mountain and Biltmore Village.

The meeting included a brief period for public questions, demonstrating the County's commitment to transparency and addressing citizen concerns. Ms. Campbell acknowledged that the meeting was held specifically in response to public inquiries about North Fork Dam, highlighting the County’s responsiveness to community feedback. No formal votes or decisions were taken during the meeting, as its primary purpose was informational.

Looking ahead, residents can expect to see repairs being made to both North Fork and Brewell dams. While the County’s infrastructure performed as designed during Hurricane Helene, preventing a catastrophic failure, ongoing maintenance and improvements are essential. County officials remain available to answer any further questions the public may have regarding our water resources and dam safety. This meeting demonstrated that proactive planning and robust infrastructure, like the County's dams and spillways, played a vital role in protecting our community during a significant weather event.
