About this dam

Old Crescent Lake Dam

Old Crescent Lake Dam, located in Goldsboro, North Carolina, is a privately owned earth dam with a primary purpose of recreation. With a hydraulic height of 13.1 feet and a structural height of 16.5 feet, the dam sits on the Poplar Branch river and offers a serene surface area of 7 acres for water enthusiasts. The dam has a storage capacity of 47 acre-feet and serves as a popular spot for recreational activities such as fishing and boating.

Despite its recreational appeal, Old Crescent Lake Dam poses a high hazard potential with an unsatisfactory condition assessment as of December 2019. The dam has not been inspected in over a year, raising concerns about its safety and maintenance. With a drainage area of 250 square miles, the dam plays a crucial role in water resource management in the region, making regular inspections and maintenance a priority to ensure public safety and environmental protection.

As climate change continues to impact water resources, the importance of properly maintaining dams like Old Crescent Lake Dam becomes increasingly vital. With its proximity to residential areas and the potential for high hazard, stakeholders must prioritize regular inspections, risk assessments, and emergency preparedness to mitigate any potential threats posed by the dam. Investing in the upkeep and safety of this recreational structure will not only benefit the local community but also contribute to sustainable water resource management in the face of climate challenges.

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 Old Crescent Lake Dam

Where does the data for Old Crescent 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 High 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.
