Summary
This private dam has a hydraulic height of 17 feet and a structural height of 20 feet, with a length of 250 feet. The dam has a storage capacity of 52 acre-feet, with a normal storage level of 23 acre-feet.
While Pyron Lake Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, it is not regulated or inspected by the state. The dam is primarily earth-filled and situated on Flat Creek-TR. Despite its historical significance and multiple uses, the dam does not have a spillway and is not equipped with outlet gates.
For water resource and climate enthusiasts, Pyron Lake Dam provides an interesting case study in the management of small-scale dams for various purposes. Its location in a rural setting and lack of state regulation raise questions about the monitoring and maintenance of such structures in terms of safety and environmental impact. Further research and attention to the management of dams like Pyron Lake Dam are crucial for ensuring the sustainable use of water resources in the future.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
