Summary
Completed in 1995, this earth dam serves the primary purpose of flood risk reduction along the Doyle Creek-TR river or stream. With a height of 19.8 feet and a length of 1780 feet, Dd No 4a has a storage capacity of 743.9 acre-feet, making it a crucial asset in managing water resources in Marion County.
Despite its low hazard potential, Dd No 4a plays a significant role in debris control and flood risk reduction within the region. The dam, designed by REH & Associates, has a normal storage capacity of 94.2 acre-feet and covers a surface area of 27.7 acres. While the structure has not been rated for its condition, it falls under moderate risk assessment category (3), indicating the need for ongoing risk management measures to ensure its effective functioning in mitigating flood risks and protecting the surrounding community and environment.
Overall, Dd No 4a stands as a testament to local government efforts in water resource management and climate resilience. As a key element in the flood risk reduction strategy for Marion County, this earth dam serves as a critical infrastructure asset that requires continued monitoring and maintenance to safeguard against potential risks and ensure its long-term effectiveness in protecting the community from flooding events.

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.
