About this dam

Van Arsdale Lake Dam

Van Arsdale Lake Dam, located in Spring Lake, North Carolina, is a privately owned earth dam that was completed in 1976 for recreational purposes. This dam, standing at a hydraulic height of 22 feet and a structural height of 25 feet, holds a maximum storage capacity of 36 acre-feet and covers a surface area of 4 acres. The dam is situated on the Little River-Os, within the jurisdiction of Moore County, North Carolina.

Despite being classified as having a low hazard potential and fair condition assessment during its last inspection in 2013, Van Arsdale Lake Dam is not regulated or permitted by the state of North Carolina. It does, however, undergo regular state inspections. With no associated structures and no emergency action plan in place, it is essential to ensure that this dam continues to be monitored and maintained to prevent any potential risks or hazards that may arise. Additionally, the dam's discharge capacity and spillway specifications are not provided in the data, leaving room for further investigation and evaluation of its safety and functionality.

As a recreational dam, Van Arsdale Lake Dam serves as a popular spot for outdoor enthusiasts in the area. Its construction and design are tailored towards providing a leisurely environment for visitors to enjoy water-based activities in a picturesque setting. With its relatively small size and storage capacity, the dam may not be as prominent as other structures in the region, but it still plays a significant role in offering recreational opportunities for the local community.

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 Van Arsdale Lake Dam

Where does the data for Van Arsdale 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.
