About this dam

Gum Swamp Lake Dam

Gum Swamp Lake Dam, located in Richmond Mills, North Carolina, is a state-owned structure built in 1934 for recreational purposes along Gum Swamp Creek. The dam stands at 12 feet high with a hydraulic height of 9 feet, creating a lake with a surface area of 55 acres and a storage capacity of 173 acre-feet. Despite its age, the dam has a low hazard potential and has not been rated for its condition since an inspection in 2008.

Overlooking the scenic Gum Swamp Lake, the dam provides opportunities for fishing, boating, and wildlife observation in a tranquil setting. With a drainage area of 15,808 acres and a maximum discharge of 76 cubic feet per second, the dam serves as a key feature in the local ecosystem and offers a peaceful retreat for nature enthusiasts. Although not regulated by the state and lacking updated emergency action plans, Gum Swamp Lake Dam continues to be a beloved outdoor destination for visitors seeking a connection to water resources and climate in North Carolina.

As a vital part of the Wilmington District, Gum Swamp Lake Dam holds historical significance as a recreational oasis that has withstood the test of time. While it may not have the modern amenities or regulatory oversight of newer structures, its enduring charm and natural beauty make it a valuable asset for both the local community and water resource enthusiasts. The dam stands as a testament to the importance of preserving our natural landscapes and enjoying the wonders of water and climate in a sustainable manner.

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 Gum Swamp Lake Dam

Where does the data for Gum Swamp 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.
