Summary
This private-owned earth dam stands at a height of 20 feet and spans 790 feet in length, with a storage capacity of 106 acre-feet. Despite being regulated by the state with permitting and inspections in place, the dam has not been rated for its condition assessment, presenting a potential hazard.
Situated on Frisco Creek, the dam lacks a spillway and poses a high risk level, according to the data provided. With no information on emergency action plans or risk management measures, the dam's safety and potential impact in case of failure raise concerns for water resource and climate enthusiasts. Additionally, the absence of updated inspection records and contact information for emergency situations adds to the uncertainty surrounding the dam's current state and preparedness for unforeseen events.
The lack of available data on Runyan Lake Dam's risk management and emergency response procedures underscores the importance of proactive monitoring and maintenance for water infrastructure. Climate enthusiasts and stakeholders interested in water resource management should advocate for improved regulation, assessment, and communication protocols to ensure the safety and sustainability of dams like Runyan Lake in the face of changing climate conditions and potential hazards.

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.
