Coltrane Lake Dam dam
Coltrane Lake Dam
Coltrane Lake Dam, located in Linwood, North Carolina, serves as a crucial structure for the High Rock Lake-Tr river system. This private-owned dam primarily functions as a Fish and Wildlife Pond, providing essential habitat and recreational opportunities for the local ecosystem. With a hydraulic height of 24 feet and a structural height of 28 feet, the dam spans 380 feet in length and boasts a storage capacity of 48 acre-feet.
Despite being classified as having a low hazard potential, Coltrane Lake Dam is not regulated by the state and has not undergone recent condition assessments. The last inspection in January 2015 deemed the dam's condition as "Not Rated," raising concerns about its current structural integrity. While the dam has not experienced any reported issues, the lack of regulatory oversight and assessment updates underscore the importance of maintaining and monitoring this vital water resource.
As water resource and climate enthusiasts, it is crucial to advocate for proper inspection and maintenance protocols for structures like Coltrane Lake Dam. By ensuring regular assessments and adherence to safety guidelines, we can protect not only the surrounding environment and wildlife but also the communities that rely on these water sources for various purposes. The unique ecosystem supported by the dam underscores the need for proactive stewardship to safeguard our natural resources for future generations.

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 Coltrane Lake Dam
Where does the data for Coltrane 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.
