Glossons Lake Dam #2 dam
Glossons Lake Dam #2
Glossons Lake Dam #2, located in Linwood, North Carolina, serves as a crucial water resource for fire protection and as a habitat for small fish. This private dam, regulated by the NCDEQ Dam Safety Program, stands at a hydraulic height of 18.8 feet and a structural height of 21.3 feet. With a storage capacity of 36 acre-feet and a drainage area of 51 square miles, Glossons Lake Dam #2 plays a significant role in managing water flow in the region.
Despite its importance, Glossons Lake Dam #2 poses a high hazard potential and was last assessed as unsatisfactory in December 2020. The dam has not been modified since its construction and lacks certain safety features like spillways and outlet gates. Emergency action plans and risk assessments for the dam are also currently unavailable. With its critical role in water management and potential risks, it is essential for authorities to address the safety concerns surrounding Glossons Lake Dam #2 and implement necessary measures to ensure its integrity and the safety of nearby communities.
As water resource and climate enthusiasts, it is crucial to monitor the condition of Glossons Lake Dam #2 and advocate for comprehensive safety measures to address its high hazard potential. By working with regulatory agencies and dam safety programs, stakeholders can ensure the proper maintenance and management of this vital water infrastructure. Additionally, raising awareness about the importance of emergency preparedness and risk assessment for dams like Glossons Lake Dam #2 can help mitigate potential disasters and protect the surrounding environment and communities.

About Glossons Lake Dam #2
Where does the data for Glossons Lake Dam #2 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 below 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.

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.
