Summary
Standing at a height of 20 feet and a length of 210 feet, this dam has a storage capacity of 73 acre-feet and a low hazard potential. Despite being regulated by the state and inspected regularly, its condition assessment remains "Not Rated," raising concerns among water resource and climate enthusiasts.
With its primary purpose being fire protection, stock, and small fish pond maintenance, Failing #4 serves as a crucial structure in the local ecosystem. However, the lack of a condition assessment and emergency action plan leaves the dam vulnerable to potential risks and disasters. As the dam is not rated for its current state, there is a pressing need for further evaluation and risk management measures to ensure the safety of the surrounding community and the preservation of water resources in the area.
As enthusiasts in water resource and climate management, it is imperative to closely monitor the condition of Failing #4 and advocate for proper maintenance and risk assessment measures to protect both the dam and the environment it serves. By addressing the gaps in inspection and emergency preparedness, we can work towards safeguarding this crucial water infrastructure and promoting sustainable water resource management practices in the region.

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.
