Summary
Built in 1962 by the USDA NRCS, this dam stands at a height of 26 feet and has a length of 199 feet. It has a storage capacity of 56 acre-feet, with a normal storage of 32 acre-feet, covering a surface area of 4 acres and draining an area of 0.43 square miles.
This low hazard potential dam features an uncontrolled spillway with a width of 40 feet. Although its condition is currently not rated and it has not been inspected recently, the risk assessment for Hayes #4 is moderate. The dam is not regulated or permitted by the state and does not have an Emergency Action Plan in place, indicating a need for further assessment and preparedness measures to ensure the safety and resilience of the structure in the face of potential climate-related challenges.
Given its location in an area prone to severe weather events and flooding, understanding the risks associated with Hayes #4 and implementing appropriate risk management measures will be crucial for protecting downstream communities and water resources. With a focus on climate resilience and emergency preparedness, stakeholders should work towards evaluating and improving the safety and functionality of this dam to mitigate potential threats and ensure the sustainable management of water resources in the region.

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.
