Old Tryon Water Suppy Dam dam
Old Tryon Water Suppy Dam
The Old Tryon Water Supply Dam, located in Polk, North Carolina, is a vital structure managed by the local government for water supply purposes. This rockfill dam, with a structural height of 20 feet and a hydraulic height of 18 feet, impounds the Big Fall Creek (tr) and has a storage capacity of 15 acre-feet. The dam, regulated by the NCDEQ Dam Safety Program, is deemed to have a high hazard potential but is currently in fair condition as of the last inspection in April 2013.
Despite its age and high hazard potential, the Old Tryon Water Supply Dam continues to serve its primary purpose effectively. With a history dating back to an unknown completion year, the dam stands as a critical piece of infrastructure for water resource management in the region. Although details on its spillway type, volume, and discharge capacity are not provided, the dam's presence ensures a reliable water supply for the surrounding community.
As water resource and climate enthusiasts marvel at the engineering behind the Old Tryon Water Supply Dam, they also acknowledge the importance of regular inspections and maintenance to ensure its continued safety and functionality. With a designated inspection frequency and a fair condition assessment, this dam serves as a reminder of the essential role such structures play in providing water security for local populations and the need for ongoing oversight to mitigate potential risks.
Dam data reference
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 Old Tryon Water Suppy Dam
Where does the data for Old Tryon Water Suppy 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.
