Egos above Public Safety

An AI responce to questions about public strategy following Hurricane Helene

By hejost on Dec 29 2025

Introduction

The following text is an AI responce to questions concerning the nonsensical official explanation and cover-up of the sequence of events at North Fork Reservoir over 26th-27th September 2024. Describing the tensions between the policy of so called ‘resilience’ winning over the protection of lives and infrastructure prefered by local. Resilience appears to prioritise egos over the question of dam design and what REALLY WENT WRONG.

AI Thinking

In 2025, the debate over the North Fork Dam has shifted from emergency response to a deep conflict over public trust and engineering ethics. Many local residents and community advocates in Asheville and Swannanoa have voiced precisely your concern: that the official narrative of “success” prioritizes the protection of an engineering design (and the professional reputations of those who commissioned it) over the physical safety and property of those living downstream.

The following points reflect the current state of public sentiment and official defense as of late 2025:

1. The “Trust Gap” and Information withholding

A primary source of local anger is the perceived lack of transparency regarding the morning of September 27, 2024.

The Missing Footage: The city’s refusal or inability to release time-stamped surveillance footage of the fusegate tipping has led to accusations of a “cover-up” regarding the true timing of the surge [6, 12].

Contradicting the Biltmore Gauge: Locals point to the Biltmore gauging station as an unbiased record that proves a catastrophic surge occurred hours before the official “9:30 AM” tipping time. Many feel that officials are sticking to a theoretical timeline to avoid legal liability for the early destruction [10, 11].

2. Differing Definitions of “Public Safety”

The conflict stems from two fundamentally different views of the dam’s role:

The Official View: Safety is defined as the structural survival of the dam. From this perspective, the fusegate “worked” because it prevented a 6-billion-gallon breach that would have killed thousands [7, 13].

The Community View: Safety is defined as protection from the water. Residents argue that a system designed to release a “wall of water” (a dam-break wave) directly into their neighborhoods without adequate warning or a lower trigger level is a failure of public safety, regardless of whether the dam stays standing [9].

3. Resilience as “Strategic Retreat”

The city’s $250 million plan to move water mains out of the creek bed is seen by some as a silent admission that the downstream area is now a “sacrifice zone” [1, 14].

While officials call this “resilience,” critics see it as the city protecting its own assets (the pipes) while leaving private homes and lives in the same “designed” path of destruction for the next storm [4].

The fact that the fusegate is being replaced exactly as it was for $10 million reinforces the fear that the city is more committed to its 2020 design choice than to adapting the dam to protect the valley [8].

4. Community Awareness in 2025

Local awareness of these technical “trade-offs” is at an all-time high.

Town Halls: 2025 city council meetings have been marked by intense testimony from survivors demanding to know why the gates weren’t set to trigger at a lower level, such as 7 feet, to moderate the flow [5].

Individual Preparedness: Because of the perceived “ego” and lack of transparency from officials, many families in the Swannanoa Valley have stated they will no longer wait for official sirens or alerts, but will evacuate the moment any significant rainfall begins [15].

Whether the city’s strategy is a matter of “ego” or rigid adherence to dam safety protocols remains a subject of intense debate, but by late 2025, it is clear that many local people do not feel their safety was the primary priority in the dam’s design or operation.

Texas Hill Country 4 July 2025
17 dams in Kerr County TX

200 words followed by 960 words

There are 8 dams in the water catchment on the tributaries up stream of Kerrville Texas.  Most are Run-of-the-River type dam which tend to mitigate against flash floods.  Water level data provides evidence that this event was caused by high rainwater run-off volumes over a large upland  catchment area, and not a dam breach.  The United States Geological Survey ( USGS) water level data from upstream gauges show a uniform flood pattern across the three tributaries and main river — South Fork Creek, North Fork Creek, Johnson Creek and the main Guadalupe River  i.e.  no  anomaly on one particular tributary.  All gauges show a sudden spike in water level in the early morning on the 4th of July with logical time differences.

Appalachia 26/7th Sept 2024
71 dams in Buncombe County NC

Most dams were overwhelmed on the 26/27th Sept during Helene and discharges from high elevation reservoirs and lakes were the main cause of primary flood effects  such as flash floods and debris flows that led to destructive secondary block-break-away effects (mini dams) in the main rivers. Run off over steep wooded terrain was a contributary factor towards flash floods.

Terrain, Infrastructure and Flood Processes on 26/27th September 2024

by Helen Steen

The terrain in Buncombe County North Carolina is a mixture of rolling hills and steep wooded slopes, interspersed with valleys some of them dammed. Prolonged heavy rainfall over the 26 and 27th of September led to run-off over steep wooded slopes, filling creeks, rivers, reservoirs and lakes. Catastrophic flooding caused complete and partial destruction of infrastructure close to creeks and rivers, and major damages in the overflowed areas away from channels. Primary flood processes - flash floods initiated on steep hillsides and from ponds, lakes and dams, while secondary flood processes occurred when debris ladened flash floods entered flooded main water courses.

Asheville’s main water supply reservoir the North Fork Reservoir (NFR) discharged when an auxiliary spillway gate activated on 27th of September. The NFR Improvement Plan, completed in 2021, involved the construction of a mechanical automated Fusegate overflow system. The manufacturer of the Fusegate describes a dilemma inherent to the system:

“Failing too early would result in frequent replacement of the Fusegates and unnecessary lowering of the reservoir. Failing too late or not failing at all could result in overtopping of the earthen embankments, and ultimately lead to a breach of the dam.”

Activation or tipping of Fusegate units occurs when the water level rises above full pool until pre-set inflow rates to the units are reached. The system consists of eight units in series designed to discharge stepwise one after another, until the water level recedes, so downstream areas are protected from a flash flood. Why only one Fusegate unit activated can be understood by way of the previously mentioned dilemma inherent to the system, however described in terms of pre-set inflow rates; too high inflow rate risks a flash flood while too low inflow rate risks a dam breach.

On the 27th of September, by the time unit No. 1 tipped over, when the pre-set inflow rate was reached, water in the reservoir had risen to a critical level. The inflow rate to the other seven units was not reached so they remained upright. A lower pre-set inflow rate to unit No. 1 was necessary for it to have activated earlier followed at intervals by units No. 2. then No. 3 and so on until the water level fell to full pool. The resulting outflow volume would have been equal to the single unit discharge but having a lower flow rate over a longer time period, avoiding flash flood conditions downstream in North Fork Creek.

Damage to terrain and infrastructure is a function of type of flood and flood type is a function of geomorphology and infrastructure. Three types of inland flood; fluvial, pluvial and flash flood have been identified. A fluvial or river flood is when a river overflows its banks and floods surrounding land but fluvial floods do not exert powerful forces. A pluvial flood or surface water flood can become a flash flood when an extreme rainfall event creates a high velocity torrent over steep terrain or when there is a sudden release of water from an upstream dam. Flash floods exert powerful forces therefore can be very dangerous and destructive under certain circumstances.

Damage to infrastructure and terrain downstream of lakes and reservoirs such as North Fork Reservoir, Bee Tree Reservoir, Flat Top Mountain Lake and Tahoma Reservoir (McDowell Co.) can be explained by flash floods due to releases, overflows or breaches of dams, in combination with pluvial flash floods due to runoff over steep terrain. Damage to infrastructure in main water courses was due to secondary flood processes, which occurred when fluvial flooding conveyed flash flood debris flows. Secondary flood processes such as block/break-away effects occurred when debris flows became held back by obstructions, such as building, bridges or natural narrows blocking the flow until forces overcame the blockage that then broke away with increased velocity. By this means secondary flood effects became compounded as more and more debris accumulated with repeated block/break-aways adding to destructive forces.

Seventy-one dams are listed on the US National Inventory of Dams (USNID) in Buncombe County 47 of which are classified high hazard potential ie. risk to life. The few dams in existence before the Great Flood of July 1916 were washed away, so all 71 on the register were either reconstructed or constructed after 1916. Flooding on the 26/27th September 2024 caused the Swannanoa River to crest at 26.1 feet, which was more than 5 feet above the old record of 20.7 feet in 1916. High rate of rainfall over an extended period up to the 27th of September led to reservoirs and lakes failing to hold very high run-off volumes generated within their catchments. Flash floods caused by their discharges were not only destructive within downstream creek systems but caused secondary flood effects raising the hazard level in main water course due to debris flows.

Operation of the emergency Fusegate system at NFR on 27th of September prevented a breach of the dam, however the pre-set inflow activation rate for unit No.1 was too high resulting in a flash flood down North Fork Creek. In the aftermath the creek was unrecognisable according to one observer. Downstream from the confluence of the creek with the main Swannanoa River there is a bend in the river. A debris ladened flash flood originating from the North Fork Reservoir entered the flooded main river and failed to take the bend sweeping away or destroying most of the homes in Beacon Village situated on the bend. According to local news reports only 11 homes were left habitable.

The consequences of concurrent flood processes over the 26th and 27th of September 2024 were catastrophic; taking lives, destroying infrastructure, altering communities and left behind a changed landscape strewn with debris.
