Summary
This privately owned earth dam stands at a height of 28 feet and has a storage capacity of 30 acre-feet. With a spillway width of 10 feet and a low hazard potential, the dam plays a crucial role in fire protection, stock, and small fish pond management in the area.
Although not regulated by the state, J K Runyan Dam No 1 is monitored for its risk management measures, with a moderate risk assessment rating. The dam, constructed with a stone core and resting on soil foundations, covers a surface area of 3 acres and serves a drainage area of 140 square miles. While the dam has not been formally rated for its condition, it continues to play a vital role in maintaining water resources and weather patterns in the region.
Despite its lack of formal inspections and state regulation, J K Runyan Dam No 1 remains a key structure in the water resource management of the area. As climate enthusiasts and water resource advocates, it is important to recognize the role of such dams in maintaining the ecological balance and supporting various purposes in the community, from grade stabilization to fire protection and beyond.

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.
