Holly Lake Dam dam
Holly Lake Dam
Holly Lake Dam, located in Sarecta, North Carolina, is a state-owned earthen dam that was completed in 1947 for the primary purpose of recreation. Situated on Polly Run Creek, this dam has a hydraulic height of 7 feet and a structural height of 10 feet, with a length of 1040 feet. The dam has a storage capacity of 134 acre-feet, with a normal storage level of 112 acre-feet, making it a significant water resource in the area.
Despite being a state-regulated dam, Holly Lake Dam has not been rated for its condition as of the last inspection in October 2015. The dam has a significant hazard potential, highlighting the importance of regular inspections and maintenance to ensure its safety and longevity. With a maximum discharge capacity of 66 cubic feet per second, the dam plays a crucial role in managing water flow in the region, particularly during times of heavy rainfall or flooding events.
Water resource and climate enthusiasts will be fascinated by the history and significance of Holly Lake Dam, which has been a key feature in the Duplin County landscape for over seven decades. As a critical component of the local water infrastructure, the dam provides not only recreational opportunities but also important water storage and flow management capabilities for the surrounding area. Its strategic location on Polly Run Creek underscores the importance of responsible dam management practices to ensure the safety and sustainability of this vital water resource for generations to come.

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.

About Holly Lake Dam
Where does the data for Holly 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 Significant 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.
