Brinkley Twin Lakes Dam #1 dam
Brinkley Twin Lakes Dam #1
Located in Mount Holly, North Carolina, Brinkley Twin Lakes Dam #1 stands as a testament to water resource and climate conservation efforts. Built in 1950, this privately owned dam serves primarily for recreational purposes, offering a serene escape for visitors seeking tranquility amidst nature. With a height of 22 feet and a hydraulic height of 19 feet, the dam provides a storage capacity of 54 acre-feet, ensuring a steady water supply for the Catawba River-Os.
Despite its significant hazard potential, Brinkley Twin Lakes Dam #1 is currently assessed to be in fair condition, with the last inspection conducted in October 2020. While not regulated by the state, the dam undergoes regular inspections to ensure its structural integrity and safety for the surrounding community. With its close proximity to the Catawba River-Os and a drainage area of 77 square miles, the dam plays a crucial role in managing water resources and maintaining a balance between recreational enjoyment and environmental sustainability in Mecklenburg County.
As water resource and climate enthusiasts continue to advocate for responsible dam management, Brinkley Twin Lakes Dam #1 stands as a reminder of the importance of balancing human needs with environmental conservation. With its storied history and ongoing commitment to safety and maintenance, this dam serves as a symbol of harmonious coexistence between nature and human activity, offering a glimpse into the delicate balance required to ensure a sustainable future 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 Brinkley Twin Lakes Dam #1
Where does the data for Brinkley Twin Lakes Dam #1 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.
