About this dam

Henson Lake Dam

Henson Lake Dam, also known as Henson Farm Lake Dam, is a private structure located in Guilford County, North Carolina. Built in 1954 by the USDA NRCS, this Earth core dam stands at a structural height of 30 feet and a hydraulic height of 15 feet. With a primary purpose of recreation, the dam holds a maximum storage capacity of 144 acre-feet and covers a surface area of 12 acres.

Although the dam is classified as having a low hazard potential, its condition assessment is rated as poor, indicating the need for maintenance and potential repairs. The last inspection in February 2020 revealed the dam's subpar condition, prompting concerns for its long-term stability. Despite its risk assessment being moderate, with a DSAC assigned date not available, there is a need for improved risk management measures to ensure the safety and integrity of the dam for both the surrounding community and the environment.

In light of its historical significance as a recreational dam and the potential risks associated with its current condition, the Henson Lake Dam serves as a focal point for water resource and climate enthusiasts. With its location along the Reedy Fork Creek and its impact on the local ecosystem, the dam's maintenance and management are crucial for preserving its function and mitigating any potential hazards that may arise in the future.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
Poor
A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.

FAQ

About Henson Lake Dam

Where does the data for Henson Lake Dam come from?

Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.

How often is the report updated?

NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.

What does the Low hazard rating mean?

The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.

What's "% of normal"?

The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).

Can I get alerts when storage crosses a threshold?

Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
